Product Description

The MP2172C is a monolithic, step-down, switch-mode converter with built-in internal power MOSFETs. It achieves 2A of continuous output current from a 2.5V to 5.5V input voltage range, with excellent load and line regulation. The output voltage can be regulated to as low as 0.6V. The constant-on-time control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown.

The MP2172C is available in an ultra-small UTQFN package, and requires a minimal number of readily available, standard external components.

The MP2172C is ideal for a wide range of applications including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
