D1766-AL_ multiple-output transformer for Integrated Switching Regulator
Description:
The D1766-AL multiple-output transformer was developed for use with Power over Ethernet
IEEE 802.3af PD Interface with Integrated Switching Regulator. It is ideal for use in
telecommunications isolated converters and isolated power supplies.
This low-profile transformer is designed for an input voltage of 36 – 72 Volts. It features
interleaved primary and secondary windings to minimize leakage inductance and
1500 Vrms isolation between windings.
