LTC3813IG#TRPBF

DC DC Switching Controllers Overview

The LTC3813IG#TRPBF is a synchronous boost DC/DC controller from Analog Devices, designed for high-voltage applications. It operates with an input voltage range of 6.35 V to 14 V and supports a maximum input voltage of 100 V. The device features a fixed switching frequency and integrates current mode control for precise regulation. Key electrical parameters include an operating supply current of 3 mA and a junction temperature range of -40°C to +125°C. It is housed in a 16-lead SSOP package and is RoHS compliant.

DC DC Switching Controllers Feature Summary

• Synchronous boost topology for efficient step-up conversion
• Current mode control architecture for fast transient response
• Integrated soft start and power good monitoring functions
• Clock synchronization capability for multi-phase or parallel systems

DC DC Switching Controllers Applications

• Industrial sensor power supplies
• Battery-powered equipment requiring voltage boosting
• Automotive electronics within specified voltage ranges
• Telecommunications infrastructure power management

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the 100V rating applies to the absolute maximum input voltage limits rather than continuous operating conditions. Ensure compatibility with the required thermal dissipation for the SSOP-16 package under expected load conditions. Check for any regional distribution restrictions or lead time variations directly with authorized Analog Devices partners.

DC DC Switching Controllers Selection Notes

Select this component when a synchronous boost solution is required for inputs between 6.35 V and 14 V. It is suitable for designs needing clock synchronization or integrated protection features like soft start. Compare against non-synchronous alternatives if efficiency is critical. Ensure the external inductor and capacitor selections align with the 100V input stress ratings and desired output voltage specifications.

DC DC Switching Controllers Part Context

This part belongs to the LTC3813 family of high-voltage synchronous boost controllers. It shares architectural similarities with other members of the series but is distinct in its specific pinout and parameter set optimized for the 100V input class. The IG suffix denotes the industrial temperature grade, ensuring reliable operation across the full -40°C to +125°C junction temperature range.

DC DC Switching Controllers Replacement Considerations

Direct replacements may include other Analog Devices synchronous boost controllers with similar input voltage ranges and pinouts. Verify functional equivalence regarding control loop stability and switching frequency before substitution.
