Why the product work in the no-load or light load will be howling?

Reason: In order to improve the efficiency and standby power consumption of the
product under low power conditions, AC-DC products work in the skip
cycle mode under light load condition. At this time, the product is in
frequency conversion mode (normal working period is 65KHZ or 100KHZ),
the output voltage The variation is relatively large, the ripple is relatively high, but the output voltage is stable.
Solution: In the light load (less than 10%) ripple is a normal phenomenon, such as to avoid the emergence of the situation, it is recommended that customers use the load of not less than 10%.
