UCS1705S数据手册UTC中文资料规格书

描述 Description

The UTC UCS1705S is an integrated PWM controller and PowerMOSFET specifically designed for switching operation with minimalexternal components. The UTC UCS1705S is designed to provideseveral special enhancements to satisfy the needs, for example,Power-Saving mode for low standby power, Frequency Hopping ,Constant Output Power Limiting , Slope Compensation ,Over CurrentProtection (OCP), Over Voltage Protection (OVP), Over LoadProtection (OLP), Under Voltage Lock Out (UVLO), Over TemperatureProtection (OTP), etc. IC will be shutdown or can auto-restart insituations.
