- Multi-Mode Control
The operation mode switching with four steps according to load conditions achieves the optimal high efficiency and
low noise power supply systems across the full load range.
・In Standby: Auto Standby (Auto Burst-Oscillation)
・Under Low to Middle Load Conditions: 1 or 2 Bottom-Skip Quasi-Resonant Operation (Bottom-Skip QR)
・Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR) - Current-Mode Control
- Bottom-Skip Function with Delay Time Setting, enabling stable switching
- Built-in Startup Circuit, enabling low power consumption
- Auto-Standby Function with Burst-Oscillation, enabling low standby power(Input power PIN < 100mW at no load)
- Soft-ON Function, preventing the audible noise from transformer, during the standby operation (burst-oscillation)
and the dynamic load change. - Soft-Start Function
- Step-Drive Function, reducing switching noise
