The MP2148GQD-25-Z is a monolithic, step-down, switchmode converter with built-in internal power MOSFETs. It achieves 1A continuous output current from a 2.3V-to-5.5V input voltage with excellent load and line regulation. The output voltage can be regulated to as low as 0.6V.The Constant-On-Time control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-bycycle current limiting and thermal shutdown.The MP2148GQD-25-Z is available in an ultra-small QFN-6 (1.0mmx1.5mm) package and requires a minimal number of readily available standard external components.The MP2148GQD-25-Z is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile devices, and other low-power systems. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
