LTC1629CG-PG#PBF

DC DC Switching Controllers Overview

The LTC1629CG-PG#PBF is a synchronous step-down switching regulator controller from Analog Devices, designed for high-efficiency power delivery. It operates within an input voltage range of 4V to 36V and supports a fixed switching frequency of 220kHz. The device features a maximum duty cycle of 0.995 and includes two output stages with positive output configuration. Packaged in a 28-SSOP housing, it provides control characteristics such as enable, phase control, power good indication, and soft start functionality.

DC DC Switching Controllers Feature Summary

• Supports PolyPhase architecture for multi-phase buck converter applications
• Includes integrated soft start and power good monitoring capabilities
• Features phase control for synchronized multi-phase operation

DC DC Switching Controllers Applications

• High current low voltage power supplies
• Server and workstation motherboard VRMs
• Industrial equipment power distribution

DC DC Switching Controllers Procurement Notes

Verify the specific suffix PG against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range of 0°C to 85°C. Confirm RoHS compliance status through manufacturer documentation before integration into production designs.

DC DC Switching Controllers Selection Notes

Select this controller when designing synchronous buck converters requiring precise phase alignment and high efficiency. It is suitable for applications needing adjustable output voltages via external feedback networks. Consider the 28-SSOP package constraints for PCB layout and thermal management requirements during the design phase.

DC DC Switching Controllers Part Context

This component belongs to the LTC1629 series of PolyPhase controllers. It is distinct from the LTC1628 dual-phase variant and the LTC1629EG-6 six-phase version. The CG grade indicates commercial temperature performance, while the PG suffix specifies the SSOP package configuration.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC1629EG-6#PBF for higher phase count applications or the LTC1628IUH#PBF for dual-phase requirements. Verify pin compatibility and control logic similarities before swapping components in existing designs.
