UCS1651S中文资料HIGH PERFORMANCE CURRENT MODE POWER SWITCH数据手册UTC规格书

描述 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.
