Highly configurable DC-DC converter features integrated H-bridge

Diodes Incorporated has introduced the AP72200, a high-current synchronous buck/boost DC-DC converter with integrated high-side and low-side H-Bridge MOSFETs. The device provides up to 97% efficiency with 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 superior voltage regulation and a constant output current of up to 2A. The design provides for a seamless transition within buck and boost operation while the broad 2.3V to 5.5V input voltage range offers flexibility of supply and provides between 2.6V to 5.14V output voltage. The high level of integration, along with low quiescent current and wide input voltage range, make the device ideal for an extensive range of portable applications including tablets, smartphones, and other battery-operated consumer devices.
