LT8302HS8E-3#PBF

Overview

The LT8302HS8E-3#PBF is a high-voltage isolated flyback switching regulator from Analog Devices, designed for ultra-low quiescent current applications. It operates with an input voltage range of 3V to 42V and delivers up to 3.6A switch current. The device features a low 12.7kHz switching frequency and supports output voltages up to 65V. Packaged in an 8-SOIC with exposed pad, it offers adjustable frequency down to 12kHz and functions as a no-optocoupler isolated converter.

Feature Summary

Ultra-low quiescent current operation enables extended battery life in portable systems
Integrated high-voltage switch eliminates external MOSFET requirements
No-optocoupler design simplifies transformer design and reduces component count
Adjustable switching frequency allows optimization for efficiency or size

Applications

Battery-powered medical devices requiring long standby times
Industrial sensor nodes with isolated communication interfaces
Portable test equipment needing compact isolated power supplies
Automotive subsystems requiring AEC-Q100 qualified components

Procurement Notes

Verify the suffix E-3 corresponds to the specific pin configuration and thermal performance required for your layout. Confirm that the HS grade meets your operating temperature range specifications. Ensure compatibility with your transformer design given the no-optocoupler feedback architecture. Check for moisture sensitivity level requirements during storage and reflow processes.

Selection Notes

Select this part when ultra-low shutdown current is critical for battery-operated applications. Choose the HS variant if automotive-grade reliability or extended temperature performance is needed. Consider the 8-SOIC package constraints for thermal management at higher load currents. Verify that the 42V maximum input voltage aligns with your system's supply rails.

Part Context

This component belongs to the LT8302 family of ultra-low quiescent current isolated flyback converters. It shares core functionality with variants like LT8302IS8E-3#PBF but differs in temperature grade and packaging options. The HS designation indicates automotive qualification under AEC-Q100 standards, distinguishing it from standard industrial grades within the same product line.
