Datasheet

概要

The MP2152 is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs. The MP2152 achieves 2A of continuous output current from a 2.5V 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 eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MP2152 is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile devices, and other low-power systems.

The MP2152 requires a minimal number of readily available, standard external components, and is available in ultra-small SOT563 or UTQFN (1.2mmx1.6mm) packages.
