SC4501EVB

The SC4501STDEVB is an evaluation board to evaluate SC4501 step up switching regulator with soft start. The SC4501 is a high frequency current mode step up switching regulator with an integrated 2A power transistor. Its high switching frequency (programmable up to 2MHz) allows the use of tiny surface mount external passive components. Programmable soft start eliminates high inrush current during start up. The operating frequency of the SC4501 can be set with an external resistor. The ability to set the operating frequency gives the SC4501 design flexibilities. A dedicated COMP pin allows optimization of the loop response. The SC4501 requires a minimum input of 1.4V to operate.
