SC4503 - 1.3MHz Step-Up Switching Regulator

General 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 components.

Key Features

  • a combined shutdown and soft-start pin. The optional soft-start function eliminates high input current and output overshoot during start-up. The internal compensation network accommodates a wide range of voltage conversion ratios. The internal switch is rated at 34V www. DataSheet4U. com making the device suitable for high voltage.
