Texas Instruments LM851772Q1EVM-PD Evaluation Module

Texas Instruments LM851772Q1EVM-PD Evaluation Module evaluates the performance of the LM851772-Q1 wide-input-voltage buck-boost controller for USB-PD applications. The module supports adjustable output voltage via a feedback resistor divider or I2C interface, current monitor or limiter configuration, cable drop compensation, output disconnect, programmable input undervoltage lockout, and constant-voltage and constant-current options.

The TI LM851772Q1EVM-PD Evaluation Module provides jumper-adjustable device settings and an I2C interface for additional power-supply configuration. The module can connect directly to the TPS26742EQ1EVM Type-C Power Delivery controller evaluation module for a complete USB-PD application. Applications include USB Type-C® power delivery, wireless charging, industrial and rugged PCs, and DC/DC modules.
