LT8494EUF#TRPBF

Overview

The LT8494EUF#TRPBF is a monolithic switching regulator from Analog Devices, packaged in a 20-lead TSSOP with an exposed pad. It supports adjustable switching frequencies ranging from 250kHz to 1.5MHz and operates with input voltages between 1V and 32V. The device delivers up to 2A output current and can generate output voltages from 1.202V to 70V. Quiescent current is less than 7uA during operation and drops to 0.3uA when the SWEN pin is low. It is configured for SEPIC, boost, or flyback topologies.

Feature Summary

Configurable as a SEPIC, boost, or flyback converter topology
Adjustable switching frequency range from 250kHz to 1.5MHz
Ultra-low quiescent current of 0.3uA in shutdown mode

Applications

Wide input and output range SEPIC converters
Boost converter configurations
Flyback converter designs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube. Confirm the E variant meets automotive qualification requirements if applicable. Ensure the 20-lead TSSOP EP package footprint matches the target PCB layout. Cross-reference the manufacturer datasheet for exact thermal and electrical specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring flexible topology support including SEPIC, boost, and flyback. The wide input voltage range accommodates various source conditions. Consider the adjustable frequency feature for optimizing efficiency and component size. Verify that the 2A output capability aligns with load requirements and thermal constraints within the TSSOP package.

Part Context

This part belongs to the LT8494 family of monolithic switching regulators designed by Analog Devices. The series offers versatile configuration options for different power conversion needs. The UF designation typically refers to the specific package type and temperature grade within the product line.
