Semtech SC2440A
Dual 30V Step-Down Switching Regulator with 2A Switches
The SC2440A is a constant frequency dual current-mode step-down regulator with integrated 30V switches. It produces two independent outputs from a common input power supply. Channel switching frequency can be programmed up to 2.5MHz. The two regulators switch in opposite phase, reducing input ripple current. As a result, a smaller input filtering capacitor can be used.
