High Performance Current Mode Controllers

high performance current mode controllers U3848 The UTC UC3848 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. UVLO featuring typical start-up current 20A, and VCC(ON) 12.6V, VCC(OFF) 8.1V. 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 UC3848 are fully pin-to-pin compatible with UC3842 except VREF-pin and NC-pin. VREF-pins application as application circuits. Pin FB with an 4k pull up resistor to internal reference voltage. The UC3848 also have soft-start function avoiding overshoot, and controlled driver output rise edge time t for low EMI By LianShun Electronics Co., Ltd
