ADP2387 Datasheet Step-down DC-to-dc Regulator

Manufacturer: Analog Devices

Overview: Data Sheet 20 V, 6 A, Synchronous, Step-Down DC-to-DC Regulator ADP2387.

General Description

The ADP2387 is a synchronous step-down, dc-to-dc regulator with an integrated 44 mΩ, high-side power, metal oxide semiconductor field effect transistor (MOSFET) and an 11 mΩ, synchronous rectifier MOSFET to provide a high efficiency solution in a pact 4 mm × 4 mm LFCSP.

This device uses a peak current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response.

The switching frequency of the ADP2387 can be programmed between 200 kHz to 1400 kHz.

Key Features

  • Input voltage range: 4.5 V to 20 V Integrated MOSFET: 44 mΩ typical/11 mΩ typical Reference voltage: 0.6 V ± 1% Continuous output current: 6 A Programmable current-limit threshold Programmable switching frequency: 200 kHz to 1400 kHz Precision enable and power good External compensation Internal soft start with external adjustable option Startup into a precharged output Supported by ADIsimPower design tool.
