MP2192 - Synchronous Step-Down Converter

Description

The MP2192 is a monolithic, step-down switchmode converter with built-in internal power MOSFETs.

The MP2192 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 to as low as 0.6V.

MP2192 2A, 2.5V to 5.5V, Synchronous Step-Down Converter with 25µA IQ in CSP Package DESCRIPTION The MP2192 is a monolithic, step-down switchmode converter with built-in internal power MOSFETs. The MP2192 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 to as low as 0.6V. Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MP2192 is well-suited for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems.
