DC-DC Converter from Diodes Incorporated Boosts Light Load Efficiency

Designed to help meet energy efficiency standards under light load and standby conditions, the AP65200 synchronous DC-DC buck converter from Diodes Incorporated achieves efficiency as high as 96% for a light load of 200mA and maintains efficiency above 70% down to 20mA. Its high level of integration and minimal external component count suits distributed power architectures in consumer electronics products, including TVs, monitors and set-top boxes.

Offering an input voltage range from 4.75V to 18V, the AP65200 provides asingle device solution for both 5V and 12V bus systems, and delivers up to2A continuous output current with a 3A peak. Using a simple external resistor divider, the converter output voltage can be set from as low as 0.925V up to a maximum of 16V.

With its integrated low on-resistance high- and low-side MOSFETs, the SO-8 packaged AP65200 helps reduce board space and optimizes trace layouts. In addition, externally programmable soft-start and on-chip over-current and thermal shutdown protection features ensure system stability and long-term reliability. The AP65200 synchronous DC-DC buck converter from Diodes Incorporated is priced at US$0.35 each in 10k unit quantities.
