Product Description

The MP2145 is a monolithic, step-down, switch-mode converter with internal power MOSFETs. It can achieve up to 6A of continuous output current from a 2.8V to 5.5V input voltage range, with excellent load and line regulation. The output voltage can be regulated to as low as 0.6V. Constant-on-time control provides a fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.

The MP2145 is available in a small QFN (2mmx3mm) package and requires a minimal number of readily available, standard external components.

The MP2145 is ideal for a wide range of applications, including storage (SSD, HDD), high-performance DSPs, FPGAs, and distributed power systems.
