UC3875 Product details

Description

The UTC UC3875 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 SOP-8 VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power.At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light

Features

S.
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 security.
