Overview
The LT8494EFE#TRPBF is a monolithic switching regulator from Analog Devices, housed in a 20-lead TSSOP-EP package. It supports SEPIC, boost, and flyback topologies with an input voltage range of 1V to 32V and an adjustable output voltage up to 70V. The device delivers a continuous switch current of 2A and operates at frequencies between 250kHz and 1.5MHz. Quiescent current is less than 7µA during operation and drops to 0.3µA when the SWEN pin is low. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Configurable as a SEPIC, boost, or flyback converter for versatile power conversion needs
- Ultra-low quiescent current consumption enhances efficiency in battery-powered applications
- Integrated charge pump switches enable wide input and output voltage ranges
- Adjustable switching frequency allows optimization for size and performance
Applications
- Battery-powered industrial equipment requiring high step-up ratios
- Automotive systems operating with varying input voltages
- Portable devices needing extended battery life through low standby current
- Sensor nodes and remote monitoring units with limited power budgets
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging rather than tube packaging. Confirm the component meets automotive qualification standards if used in vehicle applications. Check for RoHS compliance documentation relevant to your region. Ensure the supplier provides valid traceability records for quality assurance purposes.
Selection Notes
Choose this part when input voltages vary significantly below the required output level. The 2A switch current rating suits moderate power applications. Consider the thermal performance of the exposed pad in the TSSOP-EP package for heat dissipation. Verify that the external component selection supports the desired switching frequency range.
Part Context
This component belongs to the LT8494 family of wide input/output range converters. It shares architectural similarities with other Analog Devices regulators but offers specific topology flexibility. The device integrates control logic, drivers, and protection features into a single compact solution.
Replacement Considerations
LT8494IFE#TRPBF serves as a direct equivalent with identical electrical specifications and functionality. Both variants share the same pinout and operational characteristics. Verify package compatibility before substitution.
