The MP2110 is a monolithic step-down switch mode converter with integrated input current limit switch. The step-down converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The input average current limit can be externally programmed. It is ideal for powering portable equipment that is powered by an USB port. The MP2110 can supply 3A of load current from a 3.3V to 5.4V continuous input voltage with excellent load and line regulation. The MP2110 input can support up to 12V transient and clamp the current limit switch output at 5.65V (Typical). The Constant-On-time (COT) control scheme provides fast transient response high light-load efficiency and easy loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown. The MP2110 is available in a space saving 14 pin 3mmx3mm QFN package.
