LTC3810EUH-5#TRPBF

DC DC Switching Controllers Overview

The LTC3810EUH-5#TRPBF is a synchronous buck switching regulator controller from Analog Devices, designed for high-voltage applications. It accepts input voltages up to 60V and steps them down to adjustable output voltages ranging from 0.8V to 93% of VIN. The device utilizes a constant on-time valley current mode control architecture, enabling low duty cycle operation and fast transient response without requiring a sense resistor. It features precise per-cycle current limiting and operates within an extended temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports direct conversion from high input voltages up to 60V to lower regulated outputs
• Employs constant on-time valley current mode control for rapid transient response
• Provides accurate per-cycle current limiting without external sensing resistors
• Integrates a precision voltage reference for stable regulation

DC DC Switching Controllers Applications

• Telecommunications power distribution systems
• Automotive always-on electronic loads
• Industrial distributed DC power architectures
• High-voltage battery-powered equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the EUH package designation matches your PCB footprint requirements. Ensure the component meets RoHS compliance standards for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit inventory.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high input voltage tolerance and efficient synchronous rectification. The absence of a current sense resistor simplifies the bill of materials and reduces conduction losses. Consider the thermal performance of the QFN package for high-current implementations. Validate that the required output voltage range aligns with the 0.8V minimum specification.

DC DC Switching Controllers Part Context
