Микросхемы и комплектующие LT8315IFE#PBF

Импульсный обратноходовой DC-DC стабилизатор , регулируемый, 18В-560В вход, 630В/300мА коммутация

The LT8315IFE#PBF from Linear Technology is a 560VIN micropower no-opto isolated flyback converter with 630V/300mA switch in 20 pin TSSOP package. The device samples the output voltage from isolated flyback waveform appearing across a third winding on the transformer. Quasi-resonant boundary mode operation improves load regulation, reduces transformer size and maintains high efficiency. At start-up, the LT8315 charges its INTVCC capacitor via a current source attached to the DRAIN pin. During normal operation current source turns off and the device draws its power from a third winding on the transformer. It is used in isolated auxiliary/housekeeping power supplies, electric vehicles and battery stacks.
