5V to 50V Low Noise APD Bias Power Supply with Temperature Compensation

View Full Size Image View Original Datasheet 5V to 50V Low Noise APD Bias Power Supply with Temperature Compensation

The LT3571 is a current mode step-up DC/DC converter designed to bias avalanche photodiodes (APDs) in optical receivers with an output voltage up to 75V. The LT3571 features a high side fixed voltage drop APD current monitor with better than 10% relative accuracy over the entire temperature range. The integrated power switch, Schottky diode and APD current monitor allow a small solution footprint and low solution cost.
