Overview

PMP10726 is a synchronous 4-switch buck-boost converter which utilizes the LM5175 controller for USB Type-C car charger adapter applications. The output voltage can be selected for 5V, 9V, 15V, or 20V with a maximum output power of 50W by using I2C to adjust the TPL0401A-10 digital potentiometer. This design also uses the TPS70933 LDO to power the digital potentiometer. The LM5175 average current loop sets a maximum output current of 6.25A. Additional pulse-by-pulse current limiting is inherent in the current-mode controller.

Features
  • 6V to 30V input, output 5V @ 4.5A to 20V @ 2.5A
  • LM5175 buck-boost controller to achieve over 90% efficiency over all operating conditions
  • Compact size, slim form factor, suitable for car charger adapters
  • Solution size: 14mm x 39mm
  • 97.5% peak efficiency
