Digitally Controlled, 0.5% Accurate, Safest APD Bias Supply

General Description The MAX1932 generates a low-noise, high-voltage output to bias avalanche photodiodes (APDs) in optical receivers. Very low output ripple and noise is achieved by constant-frequency, pulse-width modulated (PWM) boost topology combined with a unique architecture that maintains r
