LTC3829IFE

DC DC Switching Controllers Overview

The LTC3829IFE is a synchronous step-down switching regulator controller from Analog Devices. It operates with an input voltage range of 4.5V to 38V and supports a programmable switching frequency between 250kHz and 770kHz. The device provides three independent outputs with voltages adjustable from 600mV to 5V, capable of delivering up to 90A total output current. It functions within a temperature range of -40°C to +125°C TJ and utilizes a 38-lead TSSOP package.

DC DC Switching Controllers Feature Summary

• Supports PolyPhase operation for high-current applications by driving multiple external N-channel MOSFET stages out of phase.
• Integrates true remote sensing via an internal differential amplifier for accurate regulation at the load point.
• Features OPTI-LOOP compensation to optimize transient response across varying output capacitance and ESR values.

DC DC Switching Controllers Applications

• High-density server power distribution networks
• Industrial equipment requiring multi-rail power supplies
• Telecommunications infrastructure systems

DC DC Switching Controllers Procurement Notes
