G1552
G1552 is High Performance Current Mode PWM Switch manufactured by Global Semiconductor.
High Performance Current Mode PWM Switch
ANALOG PWM IC
1. General Description
The G1552 is a high performance AC/DC power supply Switch for battery charger and adapter applications requirements up to 8W in an open frame design.It can meet less than 80 mW standby power.
G1552 is a current mode PWM Switch with a high voltage power MOSFET. 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 20 KHz.
Small current is needed when G1552 starts up and works,...
