Overview
The LT8495EFE#PBF is a monolithic switching regulator supporting SEPIC and Boost topologies with an adjustable frequency range of 250kHz to 1.5MHz. It features wide input voltage capabilities up to 60V and output voltages up to 70V, delivering output currents ranging from 0.08A to 1A depending on the configuration. The device integrates a power-on reset function and a watchdog timer for system reliability.
Feature Summary
- Supports both SEPIC and Boost conversion topologies for flexible input-output voltage relationships
- Integrates power-on reset and watchdog timer functions for enhanced system monitoring
- Features adjustable switching frequency allowing optimization between efficiency and component size
Applications
- Wide input range DC-DC conversion systems
- Battery-powered applications requiring SEPIC topology
- Industrial control circuits with variable input sources
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the TSSOP-EP-20 package type matches your PCB footprint requirements. Ensure the selected application circuit aligns with the desired topology (SEPIC or Boost) as performance characteristics vary significantly between configurations.
Selection Notes
Select this component when a single IC must handle both step-up and buck-boost scenarios within the same design family. Consider the adjustable frequency range to optimize external inductor and capacitor sizes. Verify that the required output current falls within the 0.08A to 1A operational window defined by the specific circuit implementation.
Part Context
This part belongs to the LT8495 series of multi-configurable DC-DC converters manufactured by Analog Devices (formerly Linear Technology). It shares architectural similarities with the LT8494 but offers distinct electrical specifications tailored for wider input ranges and higher voltage outputs in compact surface-mount packages.
Replacement Considerations
LT8495EFE#TRPBF serves as the tape-and-reel alternative to the tube-packaged LT8495EFE#PBF. Both variants share identical electrical characteristics and pinouts, differing only in shipping packaging format.
