The MP28258 is a 3A, 20V fully-integrated, synchronous, switch-mode, step-down converter in an ultra-small 2x3mm QFN package. The MP28258 is ideal for converting power from a wide 4.25V-20V input range to a 0.815V-13V output range with load current of up to 3A. It targets point-of-load designs for a wide range of space-constraint applications in consumer, storage, and networking. The MP28258 features adaptive constant on-time (COT) control method, integrated power FETs with low on-resistance Rds(on), and power-good indicator. Adaptive COT control eliminates complicated loop compensation to simplify design and increase flexibility with output capacitor selection. It also provides ultra-fast transient response and high light-load efficiency. With low Rds(on) and MPS's proprietary switching loss reduction technique, the MP28258 achieves up to 95% peak efficiency at 12V input and 5V output. "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.
