Product characteristic curve
Use of TRIM and calculation of TRIM resistance
TRIM resistance calculation formula
| UP: RT=[a R2/( R2-a)]-R3 | a=［Vref/( Vo- Vref)］×R 1 | RT is TRIM resistance a is a custom parameter with no actual meaning |
| DOWN: RT=[a R1/( R1-a)]-R3 | a=[( Vo- Vref)/ Vref] ×R1 |

Precautions
1. Please refer to the "Product Definition Instructions" for the meaning of pin definitions. If you are unclear, please consult our technical support;
2. For packaging information, please refer to "Product Shipping Packaging Information";
3. The maximum capacitive load is tested under the input voltage range and full load conditions. For details, please refer to the "Instructions for Capacitive Loads";
4. The power module will generate heat after being energized for a period of time, please do not touch it with your hands or body, otherwise it may cause burns;
5. Please check whether the wiring is correct before turning on the power, otherwise it will cause damage to the power supply;
6. Unless otherwise specified, the data in this article are measured at Ta=25℃, humidity<75, input="" nominal="" voltage="" and="" output="" rated="">
7. When testing the insulation withstand voltage between the input and output, please short-circuit all the pins of the input and output terminals and test;
8. When the product shell temperature exceeds the specified value, reasonable heat dissipation needs to be considered;
9. In order to prevent the output pins of the power module from oxidizing and affecting welding, please put them in a dry warehouse when storing;
10. Our company can provide customized power supply according to customer needs, please contact our sales department for details.
