LTC3722IGN-1#PBF

DC DC Switching Controllers Overview

The LTC3722IGN-1#PBF is a synchronous full-bridge DC/DC switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports output voltages from 800mV to 14V. The device features a fixed switching frequency of 1MHz and delivers up to 25A of output current across two phases. It utilizes a 24-SSOP package and functions reliably within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Synchronous full-bridge topology with integrated phase modulation for high efficiency
• Clock synchronization capability for noise reduction in multi-unit systems
• Built-in protection mechanisms including over-current limiting, slope compensation, and soft-start

DC DC Switching Controllers Applications

• Industrial power supplies requiring isolated outputs
• Telecommunications infrastructure equipment
• Point-of-load conversion modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the IGN variant matches the required SSOP-24 package dimensions for PCB footprint compatibility. Ensure the design supports the specified 1MHz switching frequency constraints regarding layout and component selection.

DC DC Switching Controllers Selection Notes

Select this controller when a synchronous full-bridge architecture is required for isolated or non-isolated buck applications. It is suitable for designs needing precise current mode control and synchronization capabilities. Consider the 24-SSOP package size and thermal performance relative to the 25A output requirement during the initial schematic capture phase.

DC DC Switching Controllers Part Context

This component belongs to the LTC3722 series of high-performance switching controllers. It is designed for applications demanding high efficiency and tight regulation. The part is often evaluated using the DC607A demonstration circuit board, which provides a reference design for implementing the controller in a 12V @ 35A configuration.

DC DC Switching Controllers Replacement Considerations

LTC3722EGN-1#PBF: Same functional specifications but in an EG package variant. LTC3722IGN-2#PBF: Different pinout or feature set; verify datasheet compatibility before substitution.
