H970
Switching Power Controller IC
General Description
H970 is a high performance current mode PWM controller. It’s specifically designed for AC/DC adapter, providing as high as 12W continuous power output in a wide input voltage range from 85V AC to 265V AC. The peak

output power can reach as high as 18W.The controller can be typically used in fly-back circuit topology,
formed a simplicity AC/DC adapter. The distinctively start-up circuit, by using bootstrap circuit and the
amplified of power transistors, significantly decreases the power dissipation of the start-up resistor.
