LTC3722IGN-2

DC DC Switching Controllers Overview

The LTC3722IGN-2#PBF is a synchronous full-bridge DC/DC switching controller manufactured by Analog Devices Inc. It operates at a fixed 1 MHz switching frequency and supports phase-modulated dual-output configurations for enhanced power density. The device features an integrated shutdown function and draws a typical operating supply current of 7 mA. It is designed to drive external N-channel MOSFETs in a full-bridge topology, providing isolated positive output capabilities. The component is housed in a 24-lead SSOP package with a width of 3.90 mm, suitable for surface-mount assembly.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF to confirm lead-free compliance and RoHS status. Confirm availability as Mouser indicates limited stock or special order requirements. Ensure the SSOP-24 footprint matches the PCB layout. Cross-reference the datasheet revision to verify electrical characteristics against the latest Analog Devices documentation before finalizing the bill of materials.

DC DC Switching Controllers Selection Notes

Select this controller when a fixed 1 MHz frequency is required for full-bridge applications. Compare against the LTC3722IGN-1#PBF variant if different pinout or control features are needed. Evaluate thermal performance within the -40°C to +85°C range. Consider the 800 uA output driver current capability for gate drive requirements. Use the DC607A evaluation board for initial circuit validation and performance testing.

DC DC Switching Controllers Part Context

This component belongs to the LTC3722 series of synchronous switching controllers from Analog Devices. It is specifically engineered for full-bridge converter topologies. The part is often evaluated using the DC607A demonstration board, which supports input voltages from 36V to 72V and delivers a 12V output at 35A. This context highlights its role in medium-to-high power isolated conversion scenarios.

DC DC Switching Controllers Replacement Considerations

The LTC3722IGN-1#PBF is a related variant within the same family. Verify functional equivalence regarding pinout and control logic before substitution. No other direct cross-model replacements are documented in the provided source material.
