NOTES:
1. To prevent burning out the driver, the output voltage must be 5.0VDC higher than the input voltage
2. Do NOT exceed the maximum power ratings on each model
3. With output ripple being rather low, it is recommended not to increase the additional output capacitor so s not to increase the delay while starting up
under cool start conditions
4. This series offers protection in case the output is shorted. After the short occurs, the input current will be cut off and recovers when the short is removed
5. The reference value of under voltage protection (7.6V) means that under the condition of cool start and full discharge of output, the protection starts when
input voltage is lower than 7.6V
6. Note: PWM dimming means PWM signals are converted into mimic analog voltage by internal circuits and then do the dimming. The advantage of this
approach is to reduce the EMI
