MPQ4236-AEC1

MPQ4236-AEC1

36V, 8A, Switching Current Buck-Boost Converter with Four Integrated MOSFETs and I²C-Adjustable OCP, AEC-Q100 Qualified

概要

The MPQ4236-AEC1 is a buck-boost converter with four power MOSFETs. The device can deliver up to 60W of output power at certain input supply ranges with excellent efficiency.

The MPQ4236-AEC1 is suitable for battery pre-regulators, USB power delivery (PD), and wireless charging applications. It can work well with external 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 (f_SW) (up to 2MHz) during continuous conduction mode (CCM) greatly reduces the external inductance and capacitance. Fault condition protections include constant-current (CC) limiting, output and input over-voltage protection (OVP), and thermal shutdown (TSD).

The MPQ4236-AEC1 requires a minimal number of readily available, standard external components. It is available in a small QFN-18 (3mmx4mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.
