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 200 mA and maintains efficiency above 70% down to 20 mA. 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 4.75 to 18 V, the AP65200 provides a single device for both 5- and 12-V bus systems, and delivers up to 2 A continuous output current with a 3-A peak. Using a simple external resistor divider, the converter output voltage can be set from as low as 925 mV up to a maximum of 16 V. 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 10,000 unit quantities. Diodes Incorporated
