LTC2955CDDB-2#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2955CDDB-2#TRPBF is a micro-power pushbutton on/off controller manufactured by Analog Devices Inc. It manages system power by generating a clean enable output from supply monitor inputs and debounced pushbutton signals. The device operates within an input voltage range of 1.6V to 36V and features a low operating supply current of 1.2µA. It is housed in an 8-lead DFN (3x2mm) package with exposed pad, suitable for surface mount applications.

Power Supply Controllers, Monitors Feature Summary

• Integrates automatic turn-on functionality triggered by valid power supply presence
• Provides debounced pushbutton input for reliable manual control
• Generates clean enable output signals for downstream power management

Power Supply Controllers, Monitors Applications
