General Description
L2355 is a current mode PWM power switch IC. It combines a current mode PWM controller and a power MOSFET. It is optimized for high performance off-line flyback converter application in sub 18 W range. For lower the standby power
and higher RoHS compliant, the IC offers a Burst Mode control feature and ultra-low start-up current and operating current, that is, at the condition of no load or light load,L2355 can reduce the switch frequency linearly which minimize the switching
power loss; the ultra-low startup current and operating current make a reliable power for startup design, and also large resistor can be used in the startup circuit to improve switching efficiency.
The internal synchronous slope compensation circuit reduces the possible subharmonic ...
