New PMBus Controller Targets High Density, Isolated Power Conversion Applications (Graphic: Business Wire)

Stocks in this article: ADI

Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced the ADP1051 advanced digital power controller with PMBus™ interface targeting ultra-compact, high density isolated DC-to-DC power supply systems with parallel/redundant capability. The ADP1051 is an extremely versatile digital controller with six PWM (pulse width modulation) logic outputs that can be programmed using an easy-to use graphic user interface (GUI) via the PMBus interface. The device enables high energy efficiency topologies including full bridge and active clamp forward variants with precision drive timing and control of secondary synchronous rectifiers. Energy efficiency is further optimised using adaptive dead-time compensation to improve the efficiency over the load range and programmable light load mode operation combined with low device power consumption (<100mW) to reduce system low power standby losses. The ADP1051 implements an extensive PMBus command set including the ability to accurately read input and output power measurements and enable the end-user to make intelligent system management decisions to optimize energy efficiency. The tiny size 4 x 4 mm LFCSP package makes the ADP1051 ideal for high density, ultra-compact isolated DC-to-DC power module or embedded designs for networking, communications and industrial applications ranging typically from 100 W upwards.

The ADP1051 power controller is easily programmed using an intuitive graphical-user interface which enables customers to design and store settings in the high reliability, internal EEPROM memory. The ADP1051 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability for increased current scaling. The device includes master/slave synchronization, reverse current protection and pre-bias start-up, accurate passive or droop current sharing between power supplies and a patented technique to identify and safely shutdown an erroneous power supply in parallel operation mode.
