Description

General part information

NCP81599 Series

The NCP81599 USB Power Delivery (PD) Controller is a synchronous buck boost that is optimized for converting battery voltage or adapter voltage into power supply rails required in desktop, docking station, hubs, and car charging accessory applications. The part is capable of delivering power to meet USB-PD standard for type C applications. The buck boost operates in a seamless manner when transitioning between buck to boost or boost to buck operation. The device is capable of operating at a 100% duty cycle. The NCP81599 drives 4 external NMOS switches, allowing for external selection of mosfets to optimize the trade offs between size, cost, and performance. The internal drivers of the device is capable of driving mosfets to meet the 100W requirement.The NCP81599 operates with a 4.5V to 28V input supply and is offered in a 5mm by 5mm 32 QFN package.
