U3848C - HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

Download the U3848C datasheet PDF. This datasheet also covers the U3848 variant, as both devices belong to the same high performance current mode pwm controllers family and are provided as variant models within a single manufacturer datasheet.

General 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

Key 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, suitable for driving N-Channel MOSFETs, can operate to duty cycles approach 70%. The U3848/A/B/C are fully pin-to-pin compatible with UC3842. But pin RT only connected a resistor to ground to.
