Digital Controller for Isolated Power Supply with PMBus Interface ADP1050
GENERAL DESCRIPTION
The ADP1050 is an advanced digital controller with a PMBus interface targeting high density, high efficiency dc-to-dc power conversion. This controller implements voltage mode control with high speed, input voltage feedforward operation for enhanced transient and noise performance. The ADP1050 has four programmable pulse-width modulation (PWM) outputs capable of controlling most high efficiency power supply topologies, with the added control of synchronous rectification (SR). The ADP1050 implements several features to enable a robust system of parallel and redundant operation for customers who require high availability. The device provides synchronization, prebias startup, and conditional overvoltage techniques to identify and safely shut down an erroneous power supply in parallel operation mode. The ADP1050 is ba……
