The TPS61061 is a high-frequency, synchronous boost converter with constant current output designed to drive up to four white LEDs. It features a 1-MHz fixed switching frequency, integrated overvoltage and advanced short-circuit protection, and allows for digital or PWM brightness control. During shutdown, the output is disconnected from the input to prevent leakage current through the LEDs.
