ADP2381 - 6 A Synchronous Step-Down Regulator

General Description

The ADP2381 is a current mode control, synchronous, stepdown, dc-to-dc regulator.

It integrates a 44 mΩ power MOSFET and a low-side driver to provide a high efficiency solution.

The ADP2381 runs from an input voltage of 4.5 V to 20 V and can deliver 6 A of output current.

Key Features

  • Input voltage: 4.5 V to 20 V Integrated 44 mΩ high-side MOSFET 0.6 V ± 1% reference voltage over temperature Continuous output current: 6 A Programmable switching frequency: 250 kHz to 1.4 MHz Synchronizes to external clock: 250 kHz to 1.4 MHz 180° out-of-phase synchronization Programmable UVLO Power-good output External compensation Internal soft start with external adjustable option Startup into a precharged output Supported by ADIsimPower design tool 20 V, 6 A Synchronous Step-Down Regulator.
