DK112 Datasheet | Dongke Semiconductor

SHENZHEN DONGKE SEMICONDUCTOR CO., LTD -DK112 HIGH PERFORMANCE SWITCH MODE POWER CONTROLLER SPECIFICATION 1. DESCRIPTION The DK112 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. - 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 pensation 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, ply 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...
