Diodes Incorporated introduces the AP72200, a high-current synchronous buck / boost DC-DC converter with integrated high-side and low-side H-bridge MOSFETs. This device can provide up to 97% efficiency, 1% voltage regulation accuracy, low quiescent current and very low output ripple.
The device uses the company's proprietary buck / boost current mode control technology to achieve excellent voltage regulation and constant output current up to 2A. This design provides a seamless transition between buck and boost operation, while a wide input voltage range from 2.3V to 5.5V provides power supply flexibility and an output voltage from 2.6V to 5.14V.
The high integration, low quiescent current, and wide input voltage range make the device ideal for a variety of portable applications including tablets, smartphones, and other battery-powered consumer devices.
