The Future of Analog IC Technology MP2148 1A Synchronous Step-down Converter with 11µA Iq in Ultra-small 1x1.5mm QFN DESCRIPTION The MP2148 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 MP2148 is available in an ultra-small QFN6 (1.0mmx1.5mm) package and requires a minimal number of readily available standard external components.
