HIGH PERFORMANCE CURRENT MODE POWER SWITCH
DESCRIPTION
The UTC UCS1651S is an integrated PWM controller and Power
MOSFET specifically designed for switching operation with minimal
external components. The UTC UCS1651S 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-restartin
situations.
