Typical Application Circuit Using SC4502 High Voltage Application

Typical Application Circuit Using SC4502 High Voltage Application. The SC4502 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 at 32V making the converter suitable for high voltage applications such as Boost, SEPIC and Flyback
