DK106

SHENZHEN DONGKE SEMICONDUCTOR CO., LTD -DK106 HIGH PERFORMANCE SWITCH MODE POWER CONTROLLER SPECIFICATION 1. DESCRIPTION The DK106 is specially design for low power switch mode control, it is widely use in small household electrical appliances. 2. APPLICATIONS ·Battery charger ·Power AC/DC adapters ·STB power supply ·Electromagnetic oven power supply ·DVD/VCD power supply ·Air conditioner power supply ·AC/DC LED driver applications ·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 a...
