Features：
·85V—265V wide range AC power input. 
· Double chip design with Bipolar Junction Transistor (BJT) to save cost. 
· Large scale MOS digital circuit design with E class BJT driving, so that to enhance its High Voltage 
Resistance capability.
· Self-power supply circuit design, no need to additional IC to supply for electricity as to reduce component 
and cost 
· 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.
