ADP1879 - Synchronous Buck Controller

Download the ADP1879 datasheet PDF. This datasheet also covers the ADP1878 variant, as both devices belong to the same synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
