DC/DC Converter Boosts Light Load Efficiency
Designed to help meet energy efficiency standards under light load and standby conditions, Diode Inc.'s 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 a single device solution for both 5V and 12V bus systems, and delivers up to 2A 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.
