Monolithic Power Systems MPQ4263 | Demoboard EVQ4263-QVE-00A

Beschreibung

The EVQ42463-QVE-00A evaluation board is designed to demonstrate the capabilities of the MPQ4263, a buck-boost converter with two integrated low-side MOSFETs (LS-FETs). The device can deliver up to 140W of peak output power (POUT) across a certain input voltage (VIN) supply range with excellent efficiency.The MPQ4263 is well-suited for USB power delivery (PD) applications. It can work well with an external USB PD controller through the I2C interface.It is recommended to read the MPQ4263 datasheet prior to making any changes to the EVQ4263-QVE-00A.
