MP2144 2A, 5.5V, 1.2MHz, 40μA IQ, COT Synchronous Step Down Switcher The Future of Analog IC Technology R DESCRIPTION The MP2144 is a monolithic, step-down, switch- O mode converter with internal power MOSFETs. It can achieve up to 2A continuous output F 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. D The constant-on-time control scheme provides E fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal D S shutdown. N 2 The MP2144 is available in small TSOT23-8 E N 8 package and requires only a minimal number of readily available standard external components.
