RT8541 Datasheet (Richtek) - Boost DC/DC Converter

RT8541, Boost DC/DC Converter

The RT8541/A is a constant frequency current mode PWM step-up DC/DC converter designed to bias avalanche photodiodes (APD) at high voltage in optical receivers.

It includes a voltage doubler charge pump to significantly reduce the noise level at output up to 90V.

The RT8541A switching frequency can

RT8541 Features

* a built-in 9ms soft-start function to eliminate the inrush current during start-up interval. The RT8541/A provides a low cost optical receiver solution and can fit in very small PCB area. The RT8541/A is available in the WQFN-16L 3x3 package. Features

* Integrated Schottky Diodes for Charge Pum
