Note:
1. If the product is not operated within the required load range, the product per
formance can‘t be guaranteed to comply with all parameters in the datasheet;
2. The maximum capacitive load offered were tested at nominal input voltage
and full load;
*Ripple and noise tested with “parallel cable” method, please see DC-DC
Converter Application Notes for specific operation methods.
3. Unless otherwise specified, parameters in this datasheet were measured under
the conditions of Ta = 25°C, humidity <75% with nominal input voltage and
rated output load;
4. All index testing methods are based on our Company’s corporate standards;
5. We can provide product customization service;
6. Specifications are subject to change without prior notice.
