PA1692NLT

Overview

The PA1692NLT is a surface mount flyback transformer manufactured by Pulse Electronics. It utilizes an EFD20 core configuration and employs Non-Potting Bonded (NPB) technology for structural integrity. Designed for board mounting, this component provides electrical isolation with a high withstand voltage insulation barrier. The unit is engineered to deliver up to 2W of power transfer capability across the isolation barrier, suitable for compact power supply applications requiring reliable magnetic coupling.

Feature Summary

• EFD20 core geometry optimized for space-constrained designs
• Non-potting bonded construction for mechanical stability
• High withstand voltage insulation barrier for safety isolation
• Surface mount package for automated assembly integration

Applications

• Flyback converter topologies in AC-DC adapters
• Low-power isolated DC-DC conversion modules
• Consumer electronics power supplies
• Industrial control system isolation stages

Procurement Notes

Verify the specific datasheet revision and electrical parameters directly with Pulse Electronics or authorized distributors before integration. Confirm that the EFD20 footprint and pinout match the target PCB layout requirements. Ensure that the thermal management strategy accounts for the 2W power handling capacity under maximum operating conditions. Cross-reference the insulation voltage ratings against the application's safety standards compliance needs.

Selection Notes

Select the PA1692NLT when a compact flyback solution with EFD20 form factor is required. This component is appropriate for designs needing up to 2W isolated power delivery. Consider the surface mount orientation and NPB construction benefits for manufacturing efficiency. Evaluate the trade-off between the EFD20 size constraints and the necessary thermal dissipation for the specific load profile.
