MP2147
5.5V, 4A, 1.2MHz, High-Efficiency, 40μA IQ Constant On-Time
Synchronous, Step-Down Switcher
DESCRIPTION
The MP2147 is a monolithic, step-down, switchmode converter with internal power MOSFETs. It can achieve up to 4A continuous output current from a 2.8V-to-5.5V input voltage 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 MP2147 is available in a small QFN2×3mm package and requires only a minimal number of...
