UC3863A Datasheet - UTC

UC3863A - LOW COST POWER-SAVING MODE PWM CONTROLLER

The UC3863A is a high performance current mode PWM controller ideally suited for low standby power. The PWM switching frequency is programmable externally at normal operation. Low VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup ci.

* UTC proprietary frequency hopping technology for Improved EMI performance.

* Power-saving mode for high light-load and standby efficiency

* Dynamic peak current limiting for constant output power

* Built-in synchronized slope compensation

* OLP with automatic recovery

* OTP
