UC3875A Datasheet (UTC) - LOW COST POWER-SAVING MODE PWM CONTROLLER

UC3875A, LOW COST POWER-SAVING MODE PWM CONTROLLER

The UTC UC3875A 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 start

UC3875A 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 FBensation

* OTP,OLP,OVP and VDD clamp for higher s
