LT8302IS8E#WPBF

Overview

The LT8302IS8E#WPBF is an isolated flyback switching voltage regulator manufactured by Analog Devices Inc. It operates with a wide input voltage range from 3V to 42V and delivers up to 3.6A of switch current. The device supports output voltages up to 65V and features adjustable switching frequency down to 12kHz. Designed for automotive applications, it holds AEC-Q100 qualification and functions within a junction temperature range of -40°C to 125°C. The component utilizes an 8-SOIC package with an exposed pad (SOIC-EP) for surface mount installation.

Feature Summary

Provides galvanic isolation between input and output without requiring an optocoupler
Supports positive or negative output configurations with single output capability
Features integrated boost/buck functionality for flexible topology implementation

Applications

Automotive power management systems requiring AEC-Q100 compliance
Isolated DC-DC conversion in industrial control circuits
Battery charger power stages utilizing EVAL-CN0509-EBZ reference designs

Procurement Notes

Verify the specific suffix #WPBF against official Analog Devices documentation to confirm tube packaging and commercial/automotive grade specifications. Confirm that the requested part matches the exact pinout and thermal pad requirements for the 8-SOIC-EP footprint. Ensure compatibility with the intended operating temperature range and input voltage constraints before finalizing procurement orders.

Selection Notes

Select this component when designing isolated flyback converters requiring high input voltage tolerance up to 42V. Consider the 3.6A switch current limit for power stage sizing and the minimum 12kHz frequency for low-noise applications. Evaluate the SOIC-EP package for thermal dissipation needs and ensure the design accommodates the required external passive components for stable regulation.

Part Context

This part belongs to the LT8302 series of no-opto isolated flyback converters. It shares architectural similarities with other members like the LT8302IS8E#WTRPBF but differs in packaging format. The series is designed for applications needing simple, compact isolated power solutions with minimal external component count compared to traditional optocoupler-based designs.
