Design files

Overview

This reference design is for USB Power Delivery (PD) battery charging applications, such as power banks or other portable devices. It employs the Buck-Boost charger BQ25713 for a wide input and output range for USB PD charging. The USB PD controller card (PMP40442) can configure the charger to run both charging or OTG via the same power path. The PMP40441/2 is compatible with PD2.0. It also demonstrates BQ25713’s capability to support PD’s Programmable Power Supply (PPS) standard. In the OTG direction (i.e. the power bank as a power source), the USB port can output a fixed USB PD voltage – 5/9/15/20 V and USB PD PPS voltage from 3.3 V to 5.9/11/21 V with smaller than 20 mV step. A USB-A port is also included as a dedicated OTG source.

Features
  • Bidirectional buck-boost operation, supports PD DRP sink and source ode
  • Supports PD up to 45 W
  • Four voltage set 5/9/15/20 V supported
  • PD PPS from 3-5.9/11/21 V with 20 mV step supported
