TPS61161QDRVRQ1 General Description

With a 40-V rated integrated switch FET, the TPS61161-Q1 is a boost converter that drives up to 10 LEDs in series. The boost converter runs at 600-kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allow for the use of small external components.

The default white LED current is set with the external sensorresistor Rset, and the feedback voltage is regulated to 200 mV, as shown in the typicalapplication. During the operation, the LED current can be controlled using the 1-wire digital interface(EasyScale protocol) through the CTRL pin. Alternatively, a pulse width modulation (PWM) signal can be applied to the CTRL pin through whichthe duty cycle determines the feedback reference voltage. In either digital or PWM mode, theTPS61161-Q1 does not burst the LED current; therefore, it does not generate audible noises on the outputcapacitor. For maximum protection, the device features integrated open LED protection thatdisables the TPS61161-Q1 to prevent the output from exceeding the absolute maximum ratings duringopen LED conditions.

The TPS61161 is available in a space-saving, 2-mm × 2-mm QFN (DRV) package with thermal pad.
