Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community TPS61169 SNVSA40A – OCTOBER 2014 – REVISED MARCH 2016 TPS61169 38-V High Current-Boost WLED Driver With PWM Control.

General Description

With a 40-V rated integrated switch FET, the TPS61169 is a boost converter that drives LEDs in series.

The boost converter has a 40-V, 1.8-A internal MOSFET with minimum 1.2-A current limit;

thus it can drive single or parallel LED strings for small- to largesize panel backlighting.
