DESCRIPTION  
The TPS61060/61/62 is a high-frequency, synchronous boost converter with constant current output to drive up  
to 5 white LEDs. For maximum safety, the device features integrated overvoltage and an advanced short-circuit  
protection when the output is shorted to ground. The device operates with 1-MHz fixed switching frequency to  
allow small external components and to simplify possible EMI problems. The device comes with three different  
overvoltage protection thresholds (14 V/18 V/23 V) to allow inexpensive and small-output capacitors with lower  
voltage ratings. The LED current is initially set with the external sense resistor Rs, and the feedback voltage is  
regulated to 500 mV or 250 mV, depending on the ILED pin configuration. Digital brightness control is  
implemented by applying a simple digital signal to the ILED pin. Alternatively, a PWM signal up to 1 kHz can be  
applied to the enable pin to control the LED brightness. During shutdown, the output is disconnected from the  
input to avoid leakage current through the LEDs.
