LT8495IUF#TRPBF

Overview

The LT8495IUF#TRPBF is a monolithic switching regulator featuring SEPIC, boost, and buck-boost topologies. It operates with an input voltage range of 3V to 60V and supports output voltages up to 70V. The device integrates adjustable frequency control from 250kHz to 1.5MHz and includes internal charge pump switches for high-frequency operation. Key features include a power-on reset generator and a watchdog timer for system reliability. It is housed in a 20-pin QFN EP package and is qualified for automotive applications.

Feature Summary

Integrates power-on reset and watchdog timer for enhanced system monitoring
Supports wide input voltage ranges suitable for diverse power sources
Features adjustable switching frequency to optimize efficiency and component size
Includes internal charge pump switches for high-frequency SEPIC operation

Applications

Automotive electronics requiring wide input voltage tolerance
Battery-powered systems with varying cell counts
Industrial equipment needing isolated or non-isolated DC-DC conversion
Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm automotive qualification status if required for your application. Ensure compatibility with the 20-pin QFN EP footprint during PCB layout. Check for any recent product change notifications that may affect pinout or specifications. Validate thermal performance requirements for the chosen operating conditions.

Selection Notes

Select this component when a single IC must handle buck, boost, and SEPIC modes across a wide voltage range. The integrated charge pump allows for higher switching frequencies, reducing passive component size. Consider the automotive grade rating for harsh environment reliability. Evaluate the need for external feedback resistors to set the desired output voltage within the supported range.

Part Context

The LT8495 belongs to Analog Devices' family of high-performance switching regulators designed for complex power conversion needs. It combines multiple converter topologies into one chip, simplifying design for applications where input voltage may rise above or fall below the output voltage. The IUF variant denotes industrial temperature range and automotive qualification.
