RT8541A, 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
