Overview
Description
The EBC10320 is a 700V GaN‑SiP 24V/100W evaluation board designed to demonstrate the performance of the RRW22101 operating with a generic shunt regulator such as the TL431, as well as other third‑party secondary‑side controllers. This configuration supports a wide range of industrial and consumer power‑supply applications.
The RRW22101 is optimized to work with our synchronous rectification (SR) controllers, RRW43010/iW610, to significantly improve efficiency (up to 95%) and meet CoC V5 Tier 2 and DOE Level VII requirements.
Power supplies designed with the RRW22101 and a generic shunt regulator—or a third‑party secondary‑side controller—can achieve high‑accuracy constant‑voltage regulation (and constant‑current capability when using a third‑party controller), fast dynamic load response, and low system cost. Typical designs using RRW2210x and TL431 can also meet no‑load power consumption below 75mW.
Features
- Up to 95% efficiency at 230VAC and 93.9% at 115VAC (full load)
- Low no‑load power consumption (<75mW at 230VAC)
- Compact design and higher power density enabled by 270kHz continuous‑conduction mode (CCM) and discontinuous‑conduction mode (DCM) operation
- Strong dynamic load response with low electromagnetic interference (EMI) and low audible noise
- Adaptive multi‑mode control (MMC) supporting both DCM and CCM for optimized transformer design
