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.

In addition, these devices offer optimum performance at low duty cycles by utilizing valley current-mode control architecture.

This allows the ADP1870/ ADP1871 to drive all N-channel power stages to regulate output voltages as low as 0.6 V.

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.
