Analog Devices intros next gen of digital power controllers with PMBus interface

APEC 2013, USA: Analog Devices Inc. (ADI) has 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.

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.
