MAX17149, MAX17129, (MAX17129 / MAX17149) 6-String WLED Drivers

The MAX17129/MAX17149 are high-efficiency drivers for white LEDs.

They are designed for small- to mediumsized LCDs that employ an array of LEDs as the light source.

An internal switch step-up controller with QuickPWM™ drives the LED array, which can be configured for up to 6 strings in parallel and

* to protect the controller from fault conditions. Separate voltagefeedback loops limit the output voltage to safe operation. The open- and short-LED detection shuts down the faulty string while keeping other strings operating normally. The devices feature cycle-by-cycle current limit on the internal
