1 High-Voltage, 5mA, Adjustable Linear General Description The current regulator operates from a 6.5V to 4V input voltage range and delivers up to a total of 5mA to one or more strings of high-brightness LEDs (HB LEDs). The output current of the is adjusted by using an external current-sense resistor in series with the LEDs. An enable input allows widerange pulsed dimming. Wave-shaping circuitry reduces EMI. The differential current-sense input increases noise immunity. The is well suited for applications requiring high-voltage input and is able to withstand automotive load-dump events up to 4V. An on-board pass element minimizes external components while providing ±.5% 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, 16-pin TQFN package and is specified over the automotive -4 C to +125 C temperature range.

Drive EN high to enable the output. THERMAL SHUTDOWN Detailed Description The is a high-current regulator capable of providing up to a total of 5mA of current to one or more strings of high-brightness LEDs. A wide operating input voltage range of +6.5V to +4V makes the ideal for automotive applications. A +5V regulated output provides up to 4mA 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 4V. 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 Maxim Integrated 5
6 High-Voltage, 5mA, Adjustable Linear power series pass device (see the Functional Diagram). The regulation point is factory set at (V - V ) = 2mV ±.5%. The regulated current is user defined by the value of R SENSE. The is a current controller internally optimized for driving the impedance range expected from one or more HB LEDs. +5V Regulator The includes a fixed +5V output regulator that delivers up to 4mA of load current for low-power applications 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 EN is low, is off. Thermal Protection The enters a thermal-shutdown mode in the event of overheating. This typically occurs in overload or output short-circuit conditions. When the junction temperature exceeds T J = +159 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 24 C (typ). The part therefore protects itself by thermally cycling in the event of a short-circuit or overload condition. Shorting to ground disables the thermal shutdown. 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 SENSE provides ground-loop immunity and low-frequency noise rejection. The LED current is given by the equation below: I LED = V SENSE /R SENSE Input Voltage Considerations For proper operation, the minimum input voltage must always be: V (M) V SENSE(MAX) + V FT(MAX + V DO(MAX) where VFT(MAX) is the total forward voltage of all seriesconnected LEDs. The minimum operating voltage of the device is +6.5V. The device operates below +6.5V; However, the output current may not meet the full regulation specification. Low-Frequency PWM at the Output The provides pulsed or chopped current dimming. Generally, HB LEDs are binned to match at their full-rated current; however, LEDs from the same bin exhibit poor matching at currents other than fullrated current. To achieve uniformity, HB LED manufacturers recommend PWM pulsing of the LED current at their full-rated value. There are two methods for producing a PWM output. One method is by pulsing the enable input (EN) while having a constant voltage at. The other method is to connect EN to and pulse both EN and. Both methods generate a regulated-amplitude PWM current (variable duty cycle) that can provide control over the LED brightness (see Figures 1 and 2).
