Overview
Data Sheet Digital Controller for Isolated Power Supply with PMBus Interface ADP1051 FEATURES GENERAL DESCRIPTION Versatile digital voltage mode controller High speed input voltage feedforward control 6 pulse-width modulation (PWM) logic outputs with 625 ps resolution Switching frequency: 49 kHz to 625 kHz Frequency synchronization as master and slave device Multiple energy saving modes Adaptive dead time compensation for efficiency optimization Low device power consumption: 100 mW typical Direct parallel control for power supplies without OR’ing devices Accurate droop current share Pre-bias startup Reverse current protection Conditional overvoltage protection Extensive fault detection and protection PMBus compliant Graphical user interface (GUI) for ease of programming On-board EEPROM for programming and data storage Available in a 24-lead, 4 mm × 4 mm LFCSP −40°C to +125°C operating temperature APPLICATIONS High density isolated dc-to-dc power supplies Intermediate bus converters High availability parallel power systems Server, storage, industrial, networking, and communications infrastructure The ADP1051 is an advanced digital controller with a PMBusTM interface targeting high density, high efficiency dc-to-dc power conversion.
This controller implements voltage mode control with high speed, input line feedforward for enhanced transient and improved noise performance.
The ADP1051 has six programmable pulse-width modulation (PWM) outputs capable of controlling most high efficiency power supply topologies, with added control of synchronous rectification (SR).
The device includes adaptive dead time compensation to improve efficiency over the load range, and programmable light load mode operation, combined with low power consumption, to reduce system standby power losses.
The ADP1051 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability or parallel connection.
The device provides sy...
