Product Description

The MP2148 is a monolithic, step-down, switch-mode converter with built-in internal power MOSFETs. It achieves 1A continuous output current from a 2.3V-to-5.5V input voltage 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 MP2148 is available in an ultra-small QFN-6 (1.0mmx1.5mm) package and requires a minimal number of readily available standard external components.

The MP2148 is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
