LT8494HFE#PBF

Overview

The LT8494HFE#PBF is a monolithic switching regulator from Analog Devices, housed in a 20-lead TSSOP package with an exposed pad. It supports SEPIC, boost, and flyback topologies with an input voltage range of 1V to 32V and an adjustable output up to 70V. The device features a programmable switching frequency 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 includes an internal charge pump for driving high-side switches.

Feature Summary

Supports multiple converter topologies including SEPIC, boost, and flyback configurations.
Features ultra-low quiescent current consumption with shutdown capability via SWEN pin.
Integrates a charge pump switch driver to facilitate high-side N-channel MOSFET control.
Allows flexible switching frequency programming across a wide range.

Applications

Automotive electronics requiring wide input voltage tolerance
Battery-powered systems needing extended runtime
Industrial power supplies with variable input sources

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure the component meets automotive qualification standards if required by the design. Cross-reference the datasheet revision date to confirm compatibility with existing design parameters.

Selection Notes

Select this component for designs requiring a single-inductor solution for non-inverting or inverting outputs. Consider the thermal performance of the TSSOP-EP package for high-current applications. Evaluate the external component count relative to alternative multi-switch solutions.

Part Context

This part belongs to the LT8494 family of wide input range switching regulators. It shares functional similarities with other Analog Devices DC/DC converters but is distinct in its integrated charge pump and multi-topology support. The HFE suffix denotes the specific temperature grade and package variant.
