LT3002ES8E#PBF

Overview

The LT3002ES8E#PBF is a micropower no-opto isolated flyback converter manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 36V and delivers up to 1W of output power. The device integrates a 36V switch and utilizes the secondary-side reference current to regulate output without an optocoupler. It is housed in an 8-lead SOIC package (ES8) with an exposed pad for thermal management.

Feature Summary

• Eliminates the need for optocouplers and feedback resistors through secondary-side regulation
• Integrates a high-voltage switch for simplified circuit design
• Supports wide input voltage ranges suitable for various DC-DC applications

Applications

• Isolated DC-DC conversion for industrial sensors
• Power supplies for communication equipment
• Battery-operated devices requiring isolation

Procurement Notes

Verify the specific suffix ES8E against the manufacturer's datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with the required operating temperature range and packaging standards before integration into the final design.

Selection Notes

Select this component when a compact, low-component-count solution for low-power isolated conversion is required. It is suitable for designs where cost and board space are critical constraints, provided the power requirements do not exceed its 1W limit.

Part Context

This part belongs to the LT300x family of no-opto isolated converters. It shares functional similarities with the LT3001 but offers higher power capability. The ES8 package variant provides a standard surface-mount footprint compatible with common PCB fabrication processes.

Replacement Considerations

LT3001ES8E#PBF offers similar functionality with lower power output. LT8302 series devices provide higher power capabilities but differ in architecture and pinout.
