NCP1381 Datasheet | onsemi

features several efficient protection options like a) a short--circuit / overload detection independent of the auxiliary voltage b) an auto--recovery brown--out detection and c) an input to externally latch the circuit in case of Overvoltage Protection or Over Temperature Protection. Features - Current--Mode Quasi--Resonant Operation - Adjustable Line Over Power Protection - Extremely Low Startup Current of 15 m A Maximum - Soft--Skip Cycle Capability at Adjustable Peak Currents - Plateau Sensing Overvoltage - Brown--Out Protection - Maximum t ON Limitation - Overpower Protection by current Sense Offset - Internal 5 ms Soft--Start Management - Short--Circuit Protection Independent from Auxiliary Level - External Latch Input Pin for an OTP Signal - Go--To--Standby Signal for the PFC Front Stage - True Frequency (t ON + t OFF) Clamp Circuit - Low and Noiseless, No--Load Standby Power - Internal Leading Edge Blanking - +500 m A / --800 m A Peak Current Drive Capability - 5 V / 10 m A Reference Voltage - These are Pb--Free Devices Typical Applications - High Power AC/DC Adapters for Notebooks, etc - Offline Battery Chargers - Set--Top Boxes Power Supplies, TV, Monitors, etc http://onsemi.
