ADP1871 - Synchronous Buck Controller

Download the ADP1871 datasheet PDF. This datasheet also covers the ADP1870 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 ADP1870/ADP1871 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable currentlimit, 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 (ADP1871 only) Resistor-programmable current-sense gain Thermal overload protection Short-circuit protection Precision enable input Integrated bootstrap diode for high-side drive Starts into.
