Texas Instruments LMG2650 | Demoboard LMG2650EVM-100

Beschreibung

The LMG2650EVM-100 is designed to provide a quick and easy platform to evaluate TI integrated GaN devices in any half-bridge topology. The board is designed to be interfaced with a larger system using the 6 power pins and 12 digital pins on the bottom edge of the board in a socket-style external connection. Power pins form the main switching loop consisting of a high-voltage DC bus, switch node and power ground. The digital pins control the LMG2650 device with PWM gate inputs, provide auxiliary power with low-voltage supplies, and report faults as a digital output. Evaluating the LMG2650EVM-100 performance is most easily demonstrated using a synchronous buck/boost motherboard from TI (LMG342X-BB-EVM). The daughtercard easily plugs into the motherboard and interfaces all power and digital control in an open-loop configuration for full system control. Additionally, a recommended footprint is provided to interface the daughtercard with a custom system for further testing.
