Overview

19-2555; Rev 1; 12/02 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 a constant-frequency, pulse-width modulated (PWM) boost topology combined with a unique architecture that maintains regulation with an optional RC or LC post filter inside its feedback loop.
A precision reference and error amplifier maintain 0.
5% output voltage accuracy.
The MAX1932 protects expensive APDs against adverse operating conditions while providing optimal bias.
Traditional boost converters measure switch current for prot...
