Typical Application Circuit Using SC4501 5V to 12V Boost Converter

Typical Application Circuit Using SC4501 5V to 12V Boost Converter. The SC4501 is a high-frequency current-mode step-up switching regulator with an integrated 2A 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
