DK112 DIP-8 AC-DC Controllers & Regulator

From the shop's description

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 DK112 Datasheet
