Description
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.
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 Pump Voltage Doubler.
- 50V, 400mA Internal Switch.
- High Side Low Noise and Accurate APD Current
Monitor.
- 650kHz Fixed Switching Frequency for RT8541 and
Adjustable Switching Frequency for R.
