Overview

1W, fixed voltage input, isolated unregulated single output, with over-temperature protection and continuous output short-circuit protection, RoHS compliant. This series is specifically designed for on-board power systems requiring a voltage rail isolated from the input supply. Suitable for applications where the input supply voltage is relatively stable (voltage variation range ±10%Vin), isolation is required between input and output (isolation voltage ≤1500VDC), and output voltage regulation is not critical. Typical applications include purely digital circuits, general low-frequency analog circuits, relay driver circuits, and data switching circuits.

Applications

Suitable for applications where the input supply voltage is relatively stable (voltage variation range ±10% Vin), galvanic isolation is required between input and output (isolation voltage ≤1500 VDC), and output voltage regulation is not critical. Typical applications include pure digital circuits, general low-frequency analog circuits, relay driver circuits, data switching circuits, and similar use cases.
