MP4248 - Buck-Boost

General Description

The MP4248 is a buck-boost converter with two integrated low-side MOSFETs (LS-FETs).

The device can deliver up to 140W of peak output power at a certain input voltage (VIN) range with excellent efficiency.

The MP4248 is suitable for USB power delivery (PD) applications.

Key Features

  • Fault condition protections include constant current (CC) current limiting with a high-side (HS) current sense, output over-voltage protection (OVP), and thermal shutdown (TSD). The MP4248 requires a minimal number of readily available, standard external components, and it is available in a QFN-20 (3mmx5mm) package.

MP4248 36V, 140W, Buck-Boost with Integrated Low-Side MOSFETs, Supports High-Side Current Sense and I2C Interface DESCRIPTION The MP4248 is a buck-boost converter with two integrated low-side MOSFETs (LS-FETs). The device can deliver up to 140W of peak output power at a certain input voltage (VIN) range with excellent efficiency. The MP4248 is suitable for USB power delivery (PD) applications. It can work with external USB PD controllers via the I2C interface. The I2C interface and one-time programmable (OTP) memory provide flexibility for configurable features. Fault condition protections include constant current (CC) current limiting with a high-side (HS) current sense, output over-voltage protection (OVP), and thermal shutdown (TSD).
