Output Specifications
Output voltage accuracy is detailed for both positive and negative outputs, along with line and load regulation. The document also covers ripple and noise levels, temperature drift coefficient, and output short circuit protection. Dynamic response to load changes is addressed.
General Specifications
General specifications include a switching frequency of 450KHz, operating and storage temperature ranges, maximum case temperature, and relative humidity conditions. The case material is black flame-retardant heat-resistant plastic, and the product weight is approximately 4.37g. The isolation voltage is 3000Vdc, and the MTBF is 200,000 hours.
Typical Product List
A detailed list of models is provided, specifying input voltage ranges, output voltage/current, input current, maximum capacitive load, ripple & noise, and efficiency percentages for both single and dual output models.
Characteristic Curves
Graphs are included showing input voltage vs. efficiency, input voltage vs. standby power consumption, and output load vs. efficiency for various models, illustrating performance characteristics under different conditions.
Design and Application Circuit Recommendations
Recommendations for design and application circuits include using a CS terminal to improve output ripple and noise, output load requirements, and recommended circuit components. A DC/DC test circuit and guidelines for input current management are also included.
Additional Notes
The document concludes with notes on ripple and noise testing using the twisted pair method, packing dimensions, and pin functions for the converters.
Method
a. Use a 12# twisted pair for connection. Set the oscilloscope bandwidth to 20MHz with a 100M bandwidth probe. Terminate with a 0.1uF polypropylene capacitor and a 47uF high-frequency low-resistance electrolytic capacitor in parallel. The oscilloscope should be set to Sample pattern.
b. Connect the input terminal to a power supply and the output terminal to an electronic load through a jig plate. Use a 30cm±2 cm sampling line. Select the power line from a wire with the appropriate diameter and insulation based on the output current flow.
Notes
1. This product cannot be used in parallel and does not support hot-plugging.
2. All index testing methods in this datasheet are based on the company's corporate standards.
3. The product specification may change at any time without prior notice.
