LTC3703IGN-5#PBF

DC DC Switching Controllers Overview

The LTC3703IGN-5#PBF is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.1V to 15V and supports output currents up to 20A. The device features a fixed switching frequency of 600kHz, though it allows for external synchronization. It utilizes a 16-SSOP package and includes integrated soft-start, current limit, and enable functions. The component is designed for high-efficiency DC-DC conversion in power management applications.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology with integrated gate drivers
• Fixed 600kHz switching frequency with clock sync capability
• Integrated soft-start and cycle-by-cycle current limiting
• Shutdown mode for low standby power consumption

DC DC Switching Controllers Applications

• Telecom equipment power distribution
• Industrial control system power supplies
• Point-of-load regulation modules
• High-density DC-DC converter designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the SSOP-16 package dimensions match your PCB footprint requirements. Check the latest datasheet revision for any updates to electrical characteristics or thermal performance data before finalizing the design.

DC DC Switching Controllers Selection Notes

Select this controller when a fixed 600kHz frequency is required for EMI filtering optimization. Ensure the external MOSFETs can handle the 20A output current and the 60V transient voltage if used in telecom environments. Consider the thermal dissipation capabilities of the SSOP-16 package for the intended application load.

DC DC Switching Controllers Part Context

This part belongs to the LTC3703 family of synchronous buck controllers. It is distinct from other variants like the LTC3703IG-5 which may offer different pinouts or frequency options. The IGN-5 designation specifically identifies the industrial temperature grade and the 16-SSOP package configuration.

DC DC Switching Controllers Replacement Considerations

Direct replacements include the LTC3703IG-5#PBF for identical functionality in alternative packages. Verify compatibility with existing PCB layouts when substituting between SSOP-16 and other package types such as QFN.
