SC4503: 1.3MHz Step-Up Switching Regulator With 1.4A Switch In ThinSOT | Semtech

The SC4503 is a 1.3MHz current-mode Step-up switch- ing Regulator with an integrated 1.4A Power Transistor Its high switching frequency allows the use of tiny sur- face-mount external passive components. The SC4503 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 com- pensation network accommodates a wide range of volt- age conversion ratios. The internal Switch is rated at 34V making the device suitable for high voltage applications such as Boost and SEPIC. By Semtech Corporation
