JW1501A - JoulWatt

JW1501A Multi-Mode Primary-Side Regulation

JW1501A/B is a high performance Primary Side Regulation (PSR) power switch with high precision CV/CC control ideal for charger applications. In CV mode, JW1501A/B adopts Multi Mode Control which uses the hybrid of AM (Amplitude Modulation) mode and (Frequency Modulation) FM mode to improve system efficiency and reliability. In CC mode, the IC uses PFM contro.
