General Description

The highl y i ntegrated F SBH-series c onsists of an integrated curr ent-mode Puls e W idth Mod ulator (PW M) and an av alanche-rugged 700V S enseFET.

It is specifically designed for high-p erformance offlin e Switched-Mode Po wer Su pplies (SMPS) with minimal external components.

The integrate d PW M controller featur es includ e a proprietary green-mode function that provi des off-time modulation to line arly decrease the s witching frequency at lig ht-load conditions t o minimiz e sta ndby power consumption.
