Datasheet Summary
1.3MHz Step-Up Switching Regulator with 1.4A Switch
POWER MANAGEMENT Description
The SC4503 is a 1.3MHz current-mode step-up switching regulator with an integrated 1.4A power transistor. Its high switching frequency allows the use of tiny surface-mount external passive ponents. The SC4503 Features a bined shutdown and soft-start pin. The optional soft-start function eliminates high input current and output overshoot during start-up. The internal pensation network acmodates a wide range of voltage conversion ratios. The internal switch is rated at 34V .. making the device suitable for high voltage applications such as Boost and SEPIC. The SC4503 is available in...
