MPQ8633B - Synchronous Step-Down Converter

General Description

The MPQ8633B is a fully integrated, highfrequency, synchronous, buck converter.

It offers a very compact solution that achieves up to 20A of output current with excellent load and line regulation over a wide input supply range.

Key Features

  • include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP). The MPQ8633B requires a minimal number of readily available, standard, external components and is available in a QFN-21 (3mmx4mm) package.

MPQ8633B 16V, 20A, Synchronous, Step-Down Converter with Adjustable Current Limit, Programmable Frequency, and Voltage Tracking DESCRIPTION The MPQ8633B is a fully integrated, highfrequency, synchronous, buck converter. It offers a very compact solution that achieves up to 20A of output current with excellent load and line regulation over a wide input supply range. The MPQ8633B operates at high efficiency over a wide output current load range. The MPQ8633B adopts an internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization. The operating frequency can be set to 600kHz, 800kHz, or 1000kHz easily with MODE configuration, allowing the MPQ8633B frequency to remain constant regardless of the input and output voltages.
