FA5526/27/28/36/37/38 series are current-mode switching power control ICs that can directly drive power MOSFETs. Low-power dissipation is achieved due to adoption of high break-down voltage CMOS process. In addition, stand-by power consumption can substantially be reduced due to a built-in start-up circuit. Many functions are incorporated in an eight pin package, reducing the number of external parts and allowing compact and high cost performance power supply.
