It is designed to drive a 6‐taps low power LED string directly form AC line input. Electrolytic capacitor is not required; so long operating life is possible. No EMI filter and PF correction circuits are needed. The LED string is configured into 6 segments. With state‐of‐art control scheme, each segment is sequentially turned on and off by tracking the input sine wave voltage. Voltage applied on IC is minimized when conducting, providing high efficiency. The AC voltage and line ‐input current could be tuned in phase, so the high PF is possible. There is no PWM switching control in the chip, also the line‐in current is tracking with the AC input with six step level, the THD i could be tuned very low. The ILED current is also programmed by external resister to fulfill various types of power requirement. The maximum supported wattage is 19.5W. The MG39134 also builds in UVLO control, over temperature and over voltage protection circuit. The device is available in e-TSSOP16, e-SOP16 package or dice form. The MG39134 provides a 7V DC output voltage for the MCU power supply application 2 Order Information Current 120mA (Max) Package Type Dice MG39134AH e-TSSOP16 MG39134AT e-SOP16 MG39134AS 3 Application Field Incandescent and Fluorescent lamp/tube replacement 4 MG39134 Data Sheet MEGAWIN 4 Pin Description 4.1 Pin Definition Pin No. Pin Name I/O Description 1 VTH1 I LED power down control pin; VTH1<1.2V à Power down 2 GND G Ground pin 3 SET1 IO Current control input for TAP1 4 SET2 IO Current control input for TAP2 5 SET3 IO Current control input for TAP3 6 SET4 IO Current control input for TAP4 7 SET5 IO Current control input for TAP5 8 SET6 IO Current control input for TAP6 9 TAP6 O Current regulator 6 output, connect it to tap of LED string 10 TAP5 O Current regulator 5 output, connect it to tap of LED string 11 TAP4 O Current regulator 4 output, connect it to tap of LED string 12 TAP3 O Current regulator 3 output, connect it to tap of LED string 13 TAP2 O Current regulator 2 output, connect it to tap of LED string 14 TAP1 O Current regulator 1 output, connect it to tap of LED string 15 VIN I High voltage input pin, connect to rectified AC 16 VDD7 O 7V DC output voltage pin 4.2 Pin Configuration MEGAWIN MG39134 Data Sheet 5 5 Block Diagram 6 Application Circuit M O V RZ 10 BD1 MB6S TVS Rin 15K Ra VTH1 Z1 5.1V Rb UVP VDD7 GND VIN SET1 TAP1 SET2 TAP2 SET3 TAP3 SET4 TAP4 SET5 TAP5 SET6 TAP6 RS1 RS2 RS3 RS4 RS5 RS6 6 MG39134 Data Sheet MEGAWIN 7 Absolute Maximum Rating Parameter Rating Unit VIN Supply Voltage -0.5 to +530 V Operating temperature -40 to +125 °C Storage temperature -55 to +155 °C Note: Operating temperature is strongly related to the power consumption of IC. 8 Electrical Characteristics Parameter Symbol Conditions Min.

But users should care the heat dissipation issue for their applications. For large wattage application, the 134 will consumes 2W~3W power. The IC’s heatsink should be firmly attached to the substrate. Aluminum or Ceramic PCB is recommended. Package Thermal Resistance The thermal resistance is around 66°C /W, junction to ambient (no air flow) Note: Rule of thumb, it is suggested that the IC surface temperature is maintained below 90 °C (Celsius degree). For ETSSOP16 package, maintain the power dissipation below 1.5W.
