LT8302ES8E#PBF

Overview

The LT8302ES8E#PBF is a monolithic no-optocoupler isolated flyback converter from Analog Devices. It operates with an input voltage range of 2.8 V to 42 V and delivers up to 3.6 A output current at 65 V switch rating. The device features a low quiescent current of 380 uA and supports adjustable switching frequencies down to 12.7 kHz. It utilizes a proprietary control loop to regulate the secondary side without requiring an optocoupler or feedback transformer, simplifying design while maintaining high efficiency in compact SOIC-8 packages.

Feature Summary

Eliminates the need for optocouplers and feedback transformers through proprietary primary-side regulation technology
Supports wide input voltage ranges suitable for various industrial and automotive power architectures
Integrates high-voltage startup circuitry to enable operation from low initial supply voltages

Applications

Industrial power supplies requiring galvanic isolation
Automotive electronics systems needing robust voltage conversion
Battery-powered equipment utilizing primary-side regulation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tin termination compliant with RoHS standards. Confirm package type matches SOIC-Narrow-EP-8 requirements for thermal management. Ensure ordering documentation specifies tube packaging rather than reel formats. Cross-reference manufacturer part numbers against distributor listings to avoid counterfeit components.

Selection Notes

Select this component when designing isolated flyback converters that require simplified feedback loops. Consider the 42 V maximum input limit for system compatibility. Evaluate thermal performance within the SOIC-8 EP package for high-current applications. Compare against non-isolated alternatives if galvanic separation is not required by the system architecture.

Part Context

This part belongs to the LT8302 family of no-opto isolated flyback controllers. It shares core regulation architecture with variants like LT8302MPS8E but differs in temperature grades and packaging options. The ES8E designation identifies the commercial grade version housed in an eight-pin narrow surface-mount package with exposed pad for heat dissipation.
