DESCRIPTION

The UTC US4657 is an integrated PWM controller and Power MOSFET specifically designed for current mode operation with minimal external components. The UTC US4657 is designed to provide several special enhancements to satisfy the needs, for example, Power-Saving mode for low standby power (<0.1W), Frequency Hopping , Constant Output Power Limiting , Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Lock Out (UVLO), and Over Temperature Protection (OTP) etc. IC will be shutdown or can auto-restart in certain situations.

FEATURES

* Internal High Voltage Start-up Circuit

* Internal 650V Power MOSFET

* Lower than 0.1W Standby Power Design

* Gate Output Maximum Voltage Clamp(15V)

* Over temperature protection

* Over voltage protection

* Leading edge blanking

* Cycle-by-Cycle current limiting

* Under Voltage Lock Out
