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
▪ Built-in start-up circuit of 500V break-down voltage that is cut off after start-up (input current after cutoff: 25µA (typ.))
▪ Low power dissipation due to adoption of high break-down voltage CMOS process
▪ Built-in frequency-decreasing function at light load
▪ Oscillating frequency
▪ Built-in latch-mode cutoff function of overload ( over current ) for FA5526/5527/5528
▪ Built-in Auto-Recovery cutoff function of overload ( over current ) for FA5536/5537/5538
▪ Built-in latch-mode cutoff function of over-voltage for 28V(typ.) at VCC pin for FA5526/5527/5528.
▪ Built-in Auto-Recovery-mode cutoff function of over-voltage for 28V(typ.) at VCC pin for FA5536/5537/5538.
▪ Built-in Under Voltage Lock-Out for VCC pin (15V : ON, 9V : OFF)
▪ 8 pins package(DIP / SO)
