The EV4255-VE-00A is an evaluation board designed to demonstrate the capabilities of the MP4255, a dual-channel, monolithic, step-down converter with an I2C interface. Each channel can deliver up to 3A (or a shared 6A) of output current (IOUT) across a wide 4V to 36V input voltage (VIN) supply range, with excellent load and line regulation.
The MP4255 is suitable for USB dedicated charging ports (DCP) and USB power delivery (PD) applications. Both channels are compatible with external USB PD controllers.
The I2C interface and one-time programmable (OTP) memory provide flexible configuration options.
The MP4255’s fault protections include constant current (CC) limiting, output over-voltage protection (OVP), short-circuit protection (SCP), and thermal shutdown (TSD).
The MP4255 requires a minimal number of readily available, standard external components, and is available in a QFN-21 (4mmx5mm) package.
