Overview
The DK112 is specially design for low power switch mode control, it is widely use in small household electrical appliances.
- 85V-265V wide range AC power input.
- 65KHz Oscillation Frequency.
- Double chip design with Bipolar Junction Transistor (BJT) to save cost.
- Large scale MOS digital circuit design with E pole BJT driving, so that to enhance its High Voltage Resistance capability.
- Self-power supply design, no need for additional IC to supply the electricity.
- Internal integrated constant high voltage current driving circuit, no need for additional resistance.
- Over current, Over loading, Over temperature, Over voltage, Output short circuit and photo-coupler Failure Protection.
- Internal Ramp Compensation circuit to keep the stability of the circuit in low voltage and high power condition.
- Internal PMW oscillation circuit with Frequency jittering control to keep EMC characteristics.
- Internal Frequency Conversion. Frequency-down in low load condition, comply with the Europe Standard (stand power<0.3W), also reduce the output voltage ripple.
