Typical Application Circuit Using SC4502H 1.5-MHz Triple-Output TFT Power Supply

Typical Application Circuit Using SC4502H 1.5-MHz Triple-Output TFT Power Supply. The SC4502H is a high-frequency current-mode step-up switching regulator with an integrated 1.4A power transistor. Its high switching frequency (2MHz) allows the use of tiny surface-mount external passive components. Programmable soft-start eliminates high inrush current during start-up. The internal switch is rated 40V for the SC4502H making the converter suitable for high voltage applications such as Boost, SEPIC and Flyback
