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 for the use of 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.
