JW1532A
High Efficiency Off-line CV Regulator
DESCRIPTION
The JW1532A is a high efficiency low cost off-line constant voltage regulator for Buck and BuckBoost topology with 650V MOSFET.
JW1532A can output 18V/12V default voltage with few external components, which decreases the system cost. In light load condition, JW1532A 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.
