DESCRI PT I ON

The UTC US1652 is an integrated PWM controller and Power

MOSFET specifically designed for switching operation with minimal

external components. The UTC US1652 is designed to provide

several special enhancements to satisfy the needs, for example,

Power-Saving mode for low standby power, Frequency Hopping ,

Constant Output Power Limiting , Slope Compensation ,Over

Current Protection (OCP), Over Voltage Protection (OVP), Over

Load Protection (OLP), Under Voltage Lock Out (UVLO), Over

Temperature Protection (OTP), etc. IC will be shutdown or can

auto-restart in situations.
