ADP1883 - Synchronous Current-Mode

Download the ADP1883 datasheet PDF. This datasheet also covers the ADP1882 variant, as both devices belong to the same synchronous current-mode family and are provided as variant models within a single manufacturer datasheet.

General Description

The ADP1882/ADP1883 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 as low as 2.75 V to 20 V Bias supply voltage range: 2.75 V to 5.5 V Minimum output voltage: 0.8 V 0.8 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 (ADP1883 only) Resistor-programmable current-sense gain Thermal overload protection Short-circuit protection Precision enable input Integrated bootstrap diode for high-s.
