UCC25702D Datasheet PDF - TI

●DESCRIPTION

●The UCC35701/UCC35702 family of pulse width modulators is intended for isolated switching power supplies using primary side control. They can be used for both off-line applications and DC/DC converter designs such as in a distributed power system architecture or as a telecom power source. The devices feature low startup current, allowing for efficient off-line start ing, yet have sufficient output drive to switch power MOSFETs in excess of 500kHz.

●FEATURES

●Optocoupler Interface

●Fault Counting Shutdown

●Fault Latch off or Automatic Shutdown

●Soft Stop Optimized for Synchronous Rectification

●1A Peak Gate Drive Output

●130A Start-up Current

●750A Operating Current
