Overview
The LT8495IFE#TRPBF is a monolithic switching regulator featuring SEPIC topology with integrated charge pump switches operating at 400kHz. It supports an input voltage range of 6V to 38V and provides an adjustable output voltage from 20V to 60V. The device delivers up to 0.08A output current. Key features include an adjustable switching frequency between 250kHz and 1.5MHz, power-on reset functionality, and a watchdog timer for system reliability.
Feature Summary
- Integrated charge pump switches enable wide input and output voltage conversion ranges within a single IC.
- Includes built-in power-on reset and watchdog timer mechanisms to ensure robust system operation.
- Offers flexible switching frequency adjustment across a broad spectrum to optimize design requirements.
Applications
- Wide input and output range SEPIC converter designs
- Systems requiring adjustable switching frequencies
- Applications needing integrated power-on reset and watchdog protection
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the IFE package variant matches your PCB footprint requirements. Ensure the selected frequency setting aligns with external component specifications for optimal performance. Cross-reference the datasheet for thermal considerations associated with the specified current load.
Selection Notes
Select this component when a SEPIC topology is required to handle input voltages that may rise above or fall below the desired output level. The integrated charge pumps simplify design by eliminating external inductors for boost/buck transitions. Consider the 0.08A current limit and the adjustable frequency range when determining external passive component values.
Part Context
This part belongs to the LT8495 family of monolithic switching regulators. It is distinct from other LT8495 variants by its specific package type and packaging format. The device integrates control logic with power stages to provide a compact solution for DC-DC conversion applications requiring high flexibility in voltage conversion ratios.
Replacement Considerations
LT8495EFE#TRPBF: Different output current capability (0.5A) and typical application configuration (Boost). LT8495EUF: Same electrical specifications but different package style (UFBGA vs MSOP). Verify pinout compatibility and thermal performance before substitution.
