LTC1922EG-1#PBF

DC DC Switching Controllers Overview

The LTC1922EG-1#PBF is a synchronous full-bridge DC/DC switching controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.8V to 10.3V and supports switching frequencies up to 1MHz. The device features a maximum duty cycle of 99% and includes clock synchronization capabilities. It provides positive, isolated output configurations via a single transistor driver stage. The component is housed in a 20-SSOP package with a width of 5.30mm and functions as a boost/buck regulator. It incorporates slope compensation and soft-start control characteristics for stable operation.

DC DC Switching Controllers Feature Summary

• Synchronous full-bridge topology with integrated ramp compensation and soft-start functionality
• Clock synchronization capability for noise reduction and multi-phase alignment
• Positive isolated output configuration suitable for transformer-coupled applications

DC DC Switching Controllers Applications

• Isolated power supplies requiring full-bridge conversion
• Industrial DC/DC converter designs
• Telecommunications power systems

DC DC Switching Controllers Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as this part may be subject to limited supply conditions. Confirm that the specific suffix #PBF indicates RoHS compliance and lead-free construction. Ensure the 20-SSOP package dimensions match your PCB footprint requirements before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a synchronous full-bridge architecture with external MOSFETs. It is suitable for designs needing clock synchronization to minimize EMI or align multiple phases. Consider the 3.8V to 10.3V supply range when designing the Vcc rail. Verify that the required operating temperature range of -40°C to 85°C meets your environmental specifications.

DC DC Switching Controllers Part Context

This component belongs to the LTC1922 family of full-bridge controllers from Analog Devices. It is designed for high-efficiency isolated power conversion. The EG-1 variant specifies the commercial temperature grade and SSOP packaging. It serves as a direct replacement for the non-PBF version in terms of function, differing primarily in compliance and packaging details.
