2. 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
3. MAIN 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.
