FAN5026 Description
The FAN5026 PWM controller provides high efficiency and regulation for two output voltages adjustable in the range of 0.9V to 5.5V required to power I/O, chip-sets, and memory banks in high-performance puters, set-top boxes, and VGA cards. Synchronous rectification and hysteretic operation at light loads contribute to high efficiency over a wide range of loads. Efficiency is enhanced by using MOSFET RDS(ON) as a...
