FS6824PG
General Description
FS6824PG is a current mode PWM controller with integrated high voltage power MOSFET. It could be used in sub 21W(Note 1) applications.
In PWM mode, FS6824PG operates in fixed frequency which is precisely set internally.FS6824PG 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 in Extended Burst Mode. Small current is needed when FS6824PG starts up and works, thus a large value resistor could be used in the startup circuit to minimize the standby power.
