MPS Presents Ultra-Compact 1A, Fixed-Frequency Synchronous Step-Down Solution

Monolithic Power Systems Inc. (MPS) announced the MP2112, a highly integrated step-down solution which requires only 5 external components for full functionality. In addition, a 1MHz operating frequency combined with a space-saving, RoHS compliant 3mm x 3mm QFN package provides designers with an ultra-compact 1A synchronous step-down solution.

The MP2112 achieves up to 95% efficiency without an external Schottky diode. With a maximum duty cycle of 100%, output can be regulated at any voltage between VIN to a low 0.6V. A wide 2.5V-6V input voltage range makes this device ideally suited for personal communications and networking products as well a handheld devices.

Additional features of the MP2112 include short circuit and thermal fault protection, a low shutdown current, integrated power MOSFETs, and an internal compensation network. Pricing for the MP2112 is $1.39 in 1K piece quantities.
