Overview

This reference design demonstrates a low-noise, efficient, bidirectional power supply that achieves less than ±0.02% full-scale (FS) current and voltage control accuracy. The design utilizes an analog feedback loop for precise current control and implements a voltage tracking circuit to minimize the power dissipation in linear stage for the source mode. This implementation enables 120W output power and can sink up to 25W with external cooling.

Features

Low-noise linear output stage, 3mVpp output noise in 20MHz bandwidth
Precise current and voltage control with accuracy better than ±0.02% full scale
Maximum power during source operation: 120W
