46 High Frequency Inductors for Core Power Applications The trend in modern power conversion is for high power density, reduced volume and increased efficiency. The drive for smaller, more efficient solutions presents a number of challenges for circuit design and component selection. Inductor selection in high current core power applications is based on a need for high peak current ratings and low high frequency losses. These two requirements lead designers in different directions resulting in a compromise solution. Designers are forced to select low inductance values to reduce inductor size (and ensure fast transient responses which results in high ripple currents needing to be absorbed by the inductor increasing losses) or select higher inductance values to reduce the ripple current and losses - but at a sacrifice of inductor size, efficiency and transient responses. The material of choice for core power multi-phase uncoupled inductors is ferrite. Core power applications require a high saturation, high frequency, low loss, wide temperature range ferrite material to be selected. The reduced core loss at high frequency (coupled with a very low Direct Current Resistance - DCR - single turn rectangular conductor) ensures high efficiency (see Figure ). Figure -Typical Three-Phase Voltage Regulator Module (VRM) Current Sensing When accurate current sensing is required, a low value resistor is commonly used to generate a voltage proportional to the output current. The introduction of such a current sense resistor increases the circuit losses along with overall converter size and cost. Using an output inductor with a tight DCR tolerance will eliminate the need for the current sense resistor. Figure Inductor Current Sensing Circuit PWM Driver Q Q V IN Coiltronics Inductor R L + C R L C s + - R l Sense PWM Sense PWM Sense Driver Driver Q Q Q Q Coiltronics Inductor R L Coiltronics Inductor L R + C + C Micro- Processor Load Figure shows a typical inductor current sense circuit, where the voltage across Cs is equal to the volt drop across the inductor DCR when the RC time constant is equal to the inductor time constant (R*C=L/RI). The low DC resistance at tight tolerance enables the inductor to also function as a current sensor (DCR Sensing). The Cooper Bussmann Coiltronics Flat-Pac Series of inductors offers the largest variety of sizes, ratings, DCR options, and stands out as the industry leader in multi-phase uncoupled core power applications. Comparing the performance of traditional ferrite inductors (such as the FP with the new DCR current sense inductors from Cooper Bussmann) it can be seen that the benefits go beyond the elimination of sensing resistors. 46

47 High Frequency Inductors for Core Power Applications From Table it can be seen that in addition to offering three different DCR values and tolerances the FP0705 has better performance over the traditional FP inductor. The FP0705 also has greater core loss stability over a wide temperature range, which is a consideration that is often overlooked during converter design. Almost all inductor specifications show room temperature values. However, the effects of increased temperature need to be accounted for as peak current ratings are reduced and losses increased at elevated temperatures. The Cooper Bussmann Coiltronics Flat-Pac Series of DCR current sensing inductors is available in footprints of 7 x 7mm, 7 x 8mm, 0 x 7mm, 0 x 8mm and x 8mm with many inductance value ranges and DCR tolerances. All parts exhibit low DCR, high peak current ratings and very low high frequency core losses that remain stable over a wide temperature range. The Flat-Pac inductors are also RoHS compliant and Halogen Free. The combination of these characteristics make the new Flat-Pac inductors ideal for high frequency, high efficiency voltage regulation modules used in computer core power applications. See Table for a detail reference of the new core power inductor solutions available from Cooper Bussmann.

49 Power Inductors Improve Reliability in High Temperature Designs Cooper Bussmann Coiltronics high current FP3 power inductors are designed for high density, medium current applications using a high temperature iron powder core material. These inductors do not exhibit the thermal aging issue frequently associated with iron powder core inductors. In fact the FP3 core is rated for 00 C without thermal degradation. The FP3 family is rated for 55 C operation. The calculations below will allow users to take advantage of this high temperature capability. 5V 4.5A V Input PWM In this example, a buck regulator will be used to convert a V input to a 5V output with a load current of 4.5A. The operating frequency was chosen to be 600 khz to reduce the size of the filter components, while still maintaining good efficiency. The converter is designed to have 0% ripple current, so a relatively low ESR output filter capacitor will be used, as is typical in switching power supplies. First calculate the needed inductance value V = L * di/dt where: V = V in - V out (voltage across the inductor) dt = On time of drive = V out /V in /frequency ΔI = Chosen above to be 0% Calculate the required inductance: L = V * dt / ΔI = (-5)*(/5/600k)/(0.*4.5) L= 4.8 μh Choose 4.7 μh, the nearest standard value. Recalculate ripple current at 3% using 4.7 μh. Second determine peak to peak flux density, B p-p : B p-p = K * L * ΔI where: K: K-factor from the adjacent table L: Inductance μh ΔI: Peak to peak ripple current (Amps) B p-p = 05*4.7*0.3*4.5 = 50 Gauss Next determine the total losses in the inductor: Total losses = DC loss + AC loss DC loss = I *DCR = 4.5 * = 0.8 W (DCR from FP3 data sheet) AC loss from table at Bp-p of 50 = 0.5 W Total Loss = DC loss + AC loss = 0.96W Finally determine the temperature rise. Total loss = 0.96W, using the table, Temperature rise is 80 C Assuming an ambient temperature of 70 C, The temperature of the inductor is T = = 50 C Application Notes - High Temp.

51 Inductor Selection for Switching Regulators Introduction/Basic Operation In switching regulator applications the inductor is used as an energy storage device. When the semiconductor switch is ON, the current in the inductor ramps up and energy is stored. When the switch turns OFF, energy is released into the load. The amount of energy stored is calculated by the formula Energy = ½L.I² (Joules), where: L is the inductance in Henrys I is the peak value of inductor current The amount by which the current changes during a switching cycle is known as the ripple current. Ripple current is defined as Vl = L.di/dt: V l is the voltage across the inductor di is the ripple current dt is the duration for which the voltage is applied I load di 0 I inductor V out ESR The following parameters need to be defined or calculated to select an inductor: Maximum input voltage Output voltage Switching frequency Maximum ripple current SD384 Duty cycle Figure : Buck Inductor Inductor current is made up of AC and DC components (Figure ). The AC component is high frequency and will flow through the output capacitor because it has a low HF impedance. A ripple voltage is produced due to the capacitor Equivalent Series Resistance (ESR) that will appear at the output of the switching regulator. This ripple voltage needs to be sufficiently low as not to effect the operation of the circuit the regulator is supplying, normally in the order of 0-500mV pk-pk. Selecting the correct ripple current impacts the size of the inductor and output capacitor. The capacitor needs to have a sufficiently high ripple current rating or it will overheat and dry out. To achieve a good compromise between inductor and capacitor size a ripple current value of 0-30% of maximum inductor current should be chosen. The current in the inductor will be continuous for output currents greater that 5-5% of full load. Application Notes - Switching 5
