JW1532B High Efficiency Off-line CV Regulator Parameters Subject to Change Without Notice DESCRIPTION The JW®1532B is a high efficiency low cost off-line constant voltage regulator for Buck and Buck- Boost topology with 650V MOSFET. JW1532B can output 18V/12V default voltage with few external components, which decreases the system cost. In light load condition, JW1532B 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.
