L2264
L2264 is Current Mode PWM Controller manufactured by LIZE.
Description
L2264 is a current mode PWM power switch IC. It bines 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 Ro HS pliant, 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,L2264 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.
