Datasheet Summary
UNISONIC TECHNOLOGIES CO., LTD U3848/A/B/C
HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS
DESCRIPTION
The UTC U3848/A/B/C is designed to provide several special enhancements to satisfy the needs: Power-Saving mode for low standby power, Over Current Protection (OCP), Over Voltage Protection (OVP), Over Load Protection (OLP), Over Temperature Protection (OTP) etc protection Features
. IC will be shutdown when either protection arise and can auto-restart. Its frequency may be defined by user through resistor RT to external ground. UVLO featuring typical start-up current 20µA, and VCC(ON) 12.6V, VCC(OFF) 8.1 . Lower typical operation current Icc 3.7mA at inactive output. The output stage,...
