MP2151
DESCRIPTION
The MP2151 is a monolithic, step-down, switchmode converter with built-in, internal power MOSFETs. The MP2151 achieves 1A of continuous output current from a 2.5V to 5.5V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.
The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Full protection features include cycle-by-cycle current limiting and thermal shutdown.
The MP2151 is ideal for a wide range of applications including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
The MP2151 requires a minimal number of readily available, standard, external ponents and is available in ultra-small SOT563 or UTQFN (1.2mmx1.6mm) packages.
