DESCRIPTION

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 20µA, and V_CC(ON)12.6V, V_CC(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 V_REF-pin and NC-pin. V_REF-pin’s application as

application circuits. Pin FB with an 4kΩ pull up resistor to internal

reference voltage. The UC3848 also have soft-start function avoiding

overshoot, and controlled driver output rise edge time t_Rfor low EMI.

FEATURES

* Low startup and operation current

* 68kHz switching frequency

* Max duty cycle 70%

* Power-saving mode for low power

* Under voltage lockout with hysteresis

* Over temperature protection

* Overload protection

* Over voltage protection

* Leading edge blanking

* Soft start
