1.1 Introduction

The LM851772Q1EVM-PD evaluation module (EVM) is designed to conveniently evaluate the performance of the LM851772-Q1 wide-VIN buck-boost controller.

The EVM is optimized for USB-PD applications and configured to operate from an input voltage range of 9V to 60V and to produce a regulated 5V to 48V output with up to a 5A load current. The EVM operates with a switching frequency of 320kHz. Most of the device settings are easily adjusted or set through jumpers, like operation mode (PSM or fPWM), bias supply, and external clock synchronization.

Through the usage of the I2C interface, the EVM covers additional parameters for configuration and adjustments of the switch mode power supply operation.

The EVM can be directly connected to the Type-C Power Delivery (PD) controller, TPS26742EQ1EVM evaluation module, for a complete USB-PD application.
