3A, 20V sync buck regulator in 2x3mm QFN package

Monolithic Power System has announced MP28258, a synchronous, switch-mode step-down converter in an ultra-small 2x3mm QFN package. It targets point-of-load designs for space-constraint applications in consumer, storage, and networking.

Key features of MP28258 include:
4.25V-20V input voltage range
0.815V-13V output voltage range
load current of up to 3A
adaptive constant on-time (COT) control method
integrated power FETs with low on-resistance Rds(on)
power-good indicator
ultra-fast transient response
high light-load efficiency

"Delivering a high-performance device in an ultra-small footprint such as the MP28258 is a testament to MPS's leading-edge process technology and design capabilities. The MP28258 is more than 50% smaller than the competition. Many MPS customers benefit from not only the performance, but also from overall system size reduction due to the miniature IC size and minimal external components, which results in more space and cost savings", said Katherine Hoang, product marketing manager at Monolithic Power Systems (MPS).

The MP28258 is available in volume from MPS and its distributors. Retail price for 1000 pieces is $1.49 each.
