DESCRIPTION
The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-bycycle current limiting and thermal shutdown. The MP2172C is ideal for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems. The MP2172C requires a minimal number of readily available, standard external components, and is available in ultra-small 1.2mmx1.6mm UTQFN packages. TYPICAL APPLICATIONFEATURES
