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.
