MP2174C 2.7V-5.5V,4A, High-Efficiency, Synchronous Step-Down Converter with Forced CCM in 2×2mm QFN DESCRIPTION The MP2174C is a monolithic, step-down, switch mode converter with built-in, internal power MOSFETs. It achieves 4A of continuous output current from a 2.7V 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 easy loop stabilization. Fault condition protections include cycle-by-cycle current limit and thermal shutdown. The MP2174C requires a minimal number of readily available, standard external components, and is available in an ultra-small QFN-12 (2mmx2mm) package.
