Dallas, Texas, US: The latest synchronous buck converter from Texas Instruments occupies just 125mm² of board space and features 90% efficiency and low noise performance. According to the company, the 50mA, 60V TPS54062 can save 20mm² more board space than other competing solutions.

The converter integrates both high- and low-side power MOSFETs. Thus, power conversion and transient protection is efficient for noise-sensitive industrial-automation, sensor-control, smart-meter, telecom, computing, and consumer designs.

This TPS54062, part of TI’s SWIFT series, can withstand high-voltage transients up to 65V while maintaining 90%efficiency at 24V^IN, 5V^OUT at 150kHz. It can be synchronised to a clock via fixed frequency to boost noise performance. Switching frequency range is 100 to 400kHz. The converter operates at 89µA; shutdown current is 1.7µA.
