JW15328B High Efficiency Off-line CV Regulator DESCRIPTION The JW15328B is a high efficiency low cost off-line constant voltage regulator for Buck and Buck- Boost topology with 650V MOSFET. JW15328B can output 12V default voltage with few external components, which decreases the system cost. In light load condition, JW15328B operates in green mode, in which the inductor peak current and the switching frequency is lower than that of full load to improve the system efficiency and the reference voltage is decreased to ensure good load regulation.
