Description
The MP4235 is a synchronous, four-switch buck-boost converter with integrated MOSFETs. The device can deliver up to 6A of output current (IOUT) at certain input supply ranges with excellent efficiency.
The MP4235 is suitable for USB power delivery (PD) and wireless charging applications. It can work well with external PD or wireless charging controllers through the I2C interface.
The I2C interface and one-time programmable (OTP) memory provide flexibility for configurable parameters.
Fault condition protections include constant-current (CC) limiting, output and input over-voltage protection (OVP), and thermal shutdown (TSD).
The MP4235 requires a minimal number of readily available, standard external components, and is available in a small QFN-19 (4mmx5mm) package with wettable flanks.
