描述 Description

Enhanced Off-line SMPS Controller The IN-PLUG IPS15 is an enhanced off-line switcher version of the IPS10. It includes additional features such as soft start and over-voltage limiting. Like the IPS10, the IPS15 was designed for low-cost, high-efficiency, low-power flyback off-line switching power supplies. It contains a shunt-regulator, a precision oscillator, a PWM with its associated comparator and loop compensation components as well as all the necessary biasing and protection circuitry (thermal shutdown, under-voltage, over-voltage and over-current).Features Low cost solution for low-power off-line flyback applicationsSimple, less critical, lower cost transformerWide range PWM for stable operation at any load and line voltageSuitable for constant-power applicationsOperates with optocoupler or bias winding for constant voltage applicationsPower shut-down for stand-by modesCycle-to-cycle over-current protectionUnder-voltage and over-voltage protection ApplicationsStandby power supplies for TV, VCR and IR remotely-controlled appliancesCordless phones and cellphone chargersPower tools fast chargers with trickle and on/offLaptops and personal digital assistantsUtility metersReplacements for bulky plug-in transformers
