UC3863 Datasheet - UTC

LOW COST POWER-SAVING MODE PWM CONTROLLER

UC3863 Features

* 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

* OTP,OLP,OVP and VDD clamp for higher

UC3863 General Description

The UC3863 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.
