The MP4236A is a buck-boost converter with four power switches. The device can deliver up to 60W of output power (POUT) at a certain input supply voltage (VIN) range with excellent efficiency.
The MP4236A is suitable for battery pre-regulators, USB Power Delivery (PD), and wireless charging applications. It can work well with external USB PD or wireless charging controllers via the I2C interface.
The I2C interface and one-time programmable (OTP) memory provide flexibility for configurable parameters.
The adjustable switching frequency (fSW, up to 2MHz) during continuous conduction mode (CCM) greatly reduces external inductor and capacitor requirements. Fault protections include constant-current (CC) limiting, output and input over-voltage protection (OVP), and thermal shutdown (TSD).
The MP4236A requires a minimal number of readily available, standard external components, and is available in a small QFN-18 (3mmx4mm) package with wettable flanks.
