1. DESCRIPTION
The MP2147GD-P 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 MP2147GD-P is available in a small QFN2×3mm package and requires only a minimal number of readily-available, standard, external components. MP2147GD-P is ideal for a wide range of applications, including storage (SSD, HDD), highperformance DSPs, FPGAs, and distributed power systems.
