1 Introduction

The USB Power Delivery (PD) 3.1 Extended Power Range (EPR) allows up to 240W of power delivery through USB-C. This is achieved through the EPR contracts that extend beyond the Standard Power Range (SPR) of USB PD 3.0, with options such as 28V/5A, 36V/5A, and 48V/5A.

The TPS26750EVM is an evaluation module for the TPS26750 IC. The TPS26750 IC is a highly integrated stand-alone USB Type-C and PD controller optimized for USB-C PD EPR applications. The TPS26750EVM supports sourcing and sinking up to 48V at 5A, in accordance with the USB-PD specification, as well as supporting battery charging applications when paired with the BQ25756EVM.

The BQ25756EVM is an evaluation module for the BQ25756 IC. The BQ25756 IC is a buck-boost battery charge controller with a wide input range of 4.2 V - 70 V, a wide output voltage range of up to 70 V, and bi-directional capabilities. The BQ25756EVM has a maximum input and output voltage of 55V, a maximum charge current of 10A, so it can be evaluated for the full 240 W range of USB Extended Power Range (EPR).
