Monolithic Power Systems MP2144

Beschreibung

The MP2144 is a monolithic, step-down, switchmode converter with internal power MOSFETs. It can achieve up to 2A continuous output current from a 2.5V–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 condition protections include cycle-by-cycle current limiting and thermal shutdown.The MP2144 is available in small TSOT23-8 package and requires only a minimal number of readily available standard external components.The MP2144 is ideal for a wide range of applications including high-performance DSPs, FPGAs, smartphones, portable instruments, and DVD drivers.
