ADP1874 Product details

Description

The ADP1874/ADP1875 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 (ADP1875 only) Resistor programmable current limit Power good with internal pull-up resistor Externally programmable soft start Thermal overload protection Short-circuit protection Standalone.
