LTC1629CG#PBF

DC DC Switching Controllers Overview

The LTC1629CG#PBF is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4 V to 36 V and supports output voltages from 0.6 V to 5 V. The device delivers up to 60 A or 90 A output current depending on the specific configuration. It utilizes a 28-SSOP package with a width of 5.30 mm. The switching frequency is fixed at 220 kHz, and the maximum duty cycle reaches 0.995. Operating temperatures span from 0°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports high-current applications through integrated synchronous rectification control
• Enables precise power management via phase control and soft-start capabilities
• Provides system status monitoring through power good signal output

DC DC Switching Controllers Applications

• Evaluation of high-current DC/DC step-down converter designs
• Development of non-isolated output power supplies
• Testing of PolyPhase controller performance under varying load conditions

DC DC Switching Controllers Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm package integrity upon receipt, as the SSOP form factor requires careful handling during inspection. Ensure storage conditions comply with moisture sensitivity level requirements to maintain solderability and electrical reliability before assembly.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring robust synchronous buck regulation with fixed frequency operation. The 28-SSOP package suits space-constrained layouts needing multiple driver outputs. Consider thermal management strategies given the high current capabilities supported by the internal architecture and external MOSFET selection.

DC DC Switching Controllers Part Context

This component belongs to the PolyPhase series of power management ICs from Analog Devices. It functions specifically as a controller rather than a complete regulator, requiring external power stages. The device integrates essential drive logic for multi-phase configurations while maintaining compatibility with standard synchronous buck topologies used in industrial and computing applications.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC1709-9 for similar buck controller functionality. Evaluation boards such as DC311A are associated with both parts for comparative testing. Verify pinout compatibility and control feature alignment when transitioning between these specific controller variants.
