ADP1879 - Synchronous Buck Controller

This page provides the datasheet information for the ADP1879, a member of the ADP1878 Synchronous Buck Controller family.

Datasheet Summary

Description

The ADP1878/ADP1879 are versatile current-mode, synchronous step-down controllers.

They provide superior transient response, optimal stability, and current-limit protection by using a constant on time, pseudo fixed frequency with a programmable current-limit, current control scheme.

Features

  • Power input voltage range: 2.95 V to 20 V On-board bias regulator Minimum output voltage: 0.6 V 0.6 V reference voltage with ±1.0% accuracy Supports all N-channel MOSFET power stages Available in 300 kHz, 600 kHz, and 1.0 MHz options No current sense resistor required Power saving mode (PSM) for light loads (ADP1879 only) Resistor programmable current limit Power good with internal pull-up resistor Externally programmable soft start Thermal overload protection Short-circuit protection Standalon.
