G1513 High Performance Current Mode PWM Controller ANALOG PWM IC 1.0 General Description The G1513 is a high performance AC/DC power supply controller for battery charger and adapter applications requirements up to 40W.It can meet less than 80 mW standby power. G1513 is a current mode PWM controller ,It operates in fixed frequency which is precisely set internally. It could operate in Extended Burst Mode at no load or light load, in which mode switching loss is minimized and the frequency is adjusted internally. To ensure that power supplies work quietly, the frequency is set beyond 22 KHz. Small current is needed when G1513 starts up and works, thus a large value resistor could be used in the startup circuit to minimize the standby power.
