The Future of Analog IC Technology MP2141Q 1.5A, Synchronous Step-Down Converter with VSEL Pin DESCRIPTION The MP2141Q is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs. The MP2141Q achieves 1.5A of continuous output currents from a 2.3V to 5.5V input voltage with excellent load and line regulation. 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 MP2141Q is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
