Description for the TPS40040EVM-001
The TPS40040EVM-001 evaluation module (EVM) is a synchronous buck converter providing a fixed1.8 V output at up to 10 A from a 5 V input bus. The EVM is designed to start up from a single supply, so no additional bias voltage is required for startup. The module uses the TPS40040 reduced pin count, low-voltage, synchronous buck controller.
