US4657 Overview
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.
