DC/DC ConverterNN1-XXSXXANT Series Typical Feature ♦ Fixed Input Voltage,Output power 1W ♦ Continuous short circuit protection ♦ Operating Temperature: -40°C to +105oC ♦ Small SMD package ♦ Isolation Voltage 1500VDC ♦ Internal patch design ♦ No external component required ♦ International standard pin-out Application Filed NN1-3V3S3V3NT is suitable for pure digital systems, low frequency analog circuits, relay-driven circuits. It is specially designed for applications where an isolated voltage is required in a distributed power supply system. It could be widely used in the below products: 1. The voltage of the input power supply is relatively stable(voltage change range:±10% Vin) 2. Isolation between input and output is required (Isolation Voltage<1500VDC); 3. Low requirements for output voltage stability and output ripple noise; Typical Product List Note 1: The typical output efficiency is based on that product is full loaded and burned-in after half an hour. Note 2: The fluctuation range of full load efficiency(%,TYP) is ±2%, full load output efficiency= total output power/module’s input power. Note 3: It is necessary to cut the power off when the output short circuit time is more than 1 second. Note 4: Ripple & Noise Tested by twisted-pair method, for details please check Ripple&Noise Test Method.
