1 General Description The current regulator operates from a 5.5V to 4V input voltage range and delivers 35mA to 35mA to one or more strings of high-brightness (HB ). The output current of the is set by using an external current-sense resistor in series with the. A dual-mode pin and on-board 2Hz ramp generator allow PWM dimming with an analog or PWM input signal. The analog control signal at dimming input allows for a theater-dimming effect to be implemented. Fast turn-on and turn-off times ensure a wide-range PWM operation, while wave-shaping circuitry minimizes EMI. The differential current-sense input increases LED current accuracy and noise immunity. The is well suited for applications requiring high-voltage input and is able to withstand load-dump events up to 45V. An on-board pass element minimizes external components while providing 3% output-current accuracy. Additional features include a 5V regulated output and short-circuit and thermal protection. The is available in a thermally enhanced, 5mm x 5mm, 2-pin TQFN package and is specified over the automotive -4 C to +125 C temperature range.

6 Functional Diagram REGULATOR TRIMMED BANDGAP 1.25V I_ REG DIFFERTIAL SSE AMPLIFIER THERMAL SHUTDOWN 21mV 2Hz RAMP GERATOR MUX POR PULSE DETECTOR Detailed Description The is a high-current regulator that operates from a wide input voltage range of 5.5V to 4V and is capable of providing up to 35mA of current to one or more strings of HB. A +5V regulated output provides up to 2mA of current to power external circuitry. In addition, the features thermal and output short-circuit protection. The wide operating voltage range helps protect the against large transients such as those found in load-dump situations up to 45V. The uses a feedback loop to control the output current. The differential voltage across the sense resistor is compared to a fixed reference voltage, and the error is amplified to serve as the drive to the internal pass device (see the Functional Diagram). The regulation point is factory-set at (V - V ) = 198 ±6mV. The regulated current is user-defined by the value of R SSE. The is a current controller internally optimized for driving the impedance range expected from one to ten or more HB. Dimming Input () The s dimming input functions with either an analog or PWM control signal. If the pulse detector detects three edges of a PWM signal with a frequency range between 8Hz and 2kHz, the synchronizes to external PWM input signal and pulse-width modulates the LED current. If an analog control signal is applied to, the compares the DC input to an internally generated 2Hz ramp to pulse-width modulate the LED current. The output current duty cycle is adjustable from % to 1% (.21V < V < 3.1V). Use the following formula to calculate the output current duty cycle: Duty cycle = (V -.21V)/(2.895V) (1) Maxim Integrated 6
7 The dimming feature can be used for LED brightness adjustment (see the Simplified Diagrams) and theater dimming. If an external PWM signal is used, the theaterdimming effect can be achieved by varying the PWM duty cycle. Figure 1 shows a simple circuit that implements theater dimming with a DC input signal. +5V Regulator The includes a fixed +5V output regulator that delivers up to 2mA of load current throughout the 6.5V to 4V input voltage range. Connect a.1μf compensation capacitor from to ground. Shorting to ground disables the thermal shutdown. When is low, is off. stays on during PWM dimming. Thermal Protection The enters a thermal-shutdown mode in the event of overheating. This typically occurs in overload or short-circuit conditions on the output. If the junction temperature exceeds T J = +155 C (typ), the internal thermal-protection circuitry turns off the series pass device. The recovers from thermal-shutdown mode once the junction temperature drops by 23 C (typ). The part therefore protects itself by thermally cycling in the event of a short-circuit or overload condition. Applications Information Programming the LED Current The uses a sense resistor across and to set the LED current. The differential sense amplifier connected across R SSE provides groundloop immunity and low-frequency noise rejection. The LED current is given by: I LED = V SSE /R SSE (2) Input-Voltage Considerations For proper operation, the minimum input voltage must always be: V (M) V RSSE(MAX) + V FT(MAX) + ΔV DO(MAX) (3) where V FT(MAX) is the maximum forward voltage of all series connected and ΔV DO(MAX) is the maximum drop output voltage. The minimum operating voltage of the device is +5.5V. Two Brightness Levels for TAIL/STOP Lights Figure 2 shows two-level brightness adjustment using the with minimum external components. Set the dimming level with a resistive divider connected to. See Equation 1 for details. V STOP D1 THEATER MG SIGNAL +5V REG.1µF RSSE TAIL R1 R2 D2 D4 D3 R SSE Figure 1. Theater Dimming Figure 2.

8 LED Current Thermal Foldback With a minimum number of external components, the provides LED current thermal foldback using a negative temperature coefficient (NTC) thermistor. Figure 3 shows a thermistor connected to and the of the. As the temperature increases, the voltage drop across R2 increases causing the LED current to decrease. I LED = [V SSE - [R2/(R2 + RT)] x ]/R1 (4) Other Applications Figure 4 shows an application circuit with the using a single BJT to provide high output current. For proper operation: V (M) > V CESAT(MAX) + V FT(MAX) + V RSSE (5) where V CESAT(MAX) is the maximum saturation voltage of the external BJT. V C1 PWM MG C2 RT R2 R1 Figure 3.
