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 (
