The DK112 is specially design for low power switch mode control, it is widely use in small household
electrical appliances.
Applications
- Battery charger
- DVD/VCD power supply
- Power AC/DC adapters ·Air conditioner power supply
- STB power supply
- AC/DC LED driver applications
- Electromagnetic oven power supply
- TV/Monitor power supply
Features
- 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. - Ramp current drive circuit included to reduce IC power loss and raise circuit efficiency.
- 4KV Anti-Static ESD test
