HIGH PERFORMANCE CURRENT MODE POWER SWITCH WITH ZERO CURRENT DETECTION
DESCRIPTION
The UTC UPS4602 is an integrated PWM controller and PowerMOSFET specifically designed for switching operation with
minimal external components. The UTC UPS4602 is designed to provide several special enhancements to satisfy the needs, for example, Power-Saving mode for low standby power (<0.3W), 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), Short Circuit Protection (SCP) , Over Temperature Protection (OTP), etc. IC will be shutdown or can auto-restart in situations.
