NEB-D Series

264~300 W Intermediate Bus Eighth Brick Dc-Dc Converter with Digital Control

NEB-D Series

The NEB-D is a series of fully regulated 1/8 brick intermediate bus dc-dc converters with advanced digital control. The converters incorporate a 32-bit ARM-based microcontroller with power-optimizing firmware designed to maximize and flatten the efficiency curve, providing peak performance across a much wider range of loading conditions. In addition, the NEB-D series provides users with a range of configurable power management features via PMBus™, including output voltage, voltage margining, fault management, precision delay ramp-up, and start/stop.
