High Efficiency Battery Charger Using Power Components
An off-line battery charger - using the Unitrode UC3906 battery charger controller chip
and a Vicor 2nd Generation DC-DC converter module - provides design flexibility, small
size, and high efficiency.
Power Components Simplify 1 kW Power Design
High-density power components simplify the design process. This document outlines a
step-by-step design example using off-the-shelf Vicor modular power components as
the primary building blocks.
Wide Range Trimming with Variable Loads
The output of Vicor 2nd Generation DC-DC converter modules can be programmed from
10 to110% of their nominal output voltage. Trimming down is easily accomplished with a
small low power resistor or potentiometer connected between the SC pin and the -S pin.
Phased Array Controller
The Phased Array Controller (PAC) Integrated Circuit enhances the performance of
power-sharing arrays of modular DC-DC converters.
