Description
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 (fSW) (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.

CHOOSING THE PROPER PARAMETERS IN FREQUENCY SPREAD SPECTRUM (FSS) DESIGNARTICLEThe frequency spread spectrum (FSS) technique has been widely applied in power converters to reduce electromagnetic interference (EMI) noise. However, in practice, there are multiple parameters in FSS design that must be considered to optimize EMI performance with minimal side effects. This article introduces FSS parameters such as modulation shape, frequency, and depth, and analyzes their impact ...
