Description

General part information

LM5036 Series

The LM5036 PWM controller, with integrated auxiliary bias supply, offers high power density for industrial isolated power applications. It contains all the features necessary to implement half-bridge power converters, using voltage-mode control, with input voltage feed-forward. This controller is intended to operate on the primary side of an isolated converter with DC input voltage up to 100 V. The controller includes features that improve power density and reliability while reducing system cost:
