  2. S8200 Introduction <Unit: mm> 2.8 2.9 <SOT-25> 1.1 -. AUK compact size package (2.9 x 2.8 x 1.1 mm) -. Space-saving package contributes to board miniaturization 1. Large Operation Voltage range  3V ~ More than 600V 2. Driving current : Max. 150mA 3. Linear Regulation Operating Using Band-gap Voltage  Very Good Load, Line Regulation and Thermal Characteristics 4. Only 1 external components required (RFB)  Very Simple Circuit, Area saving, Cost saving  SOT-25 Package (2.9×2.8 ×1.1mm) 6. Low standby current makes High Efficiency : IQ = Typ. 2mA 7. Enable PWM dimming control  Smart LED Lighting, Fashionable LED Lighting 1. ILED (LED Drive Current)  ILED = [ 600/RFB ]mA 2. PD (Power Dissipation)  PD(Total) = PD1 + PD2 -. PD1 = (VDROP – VFB) × ILED ※ ( VDROP = VOUT – VFB) -. PD2 = VCC × IQ

  3. Application Example (Low Voltage) Constant Current Driving PWM Dimming Control ☞ VS≤ 24V ☞ ILED = 600/RFB [mA] ☞ VS≤ 24V ☞ PWM Dimming Control - 3 -

  4. Application Example (Low Voltage) VAC Landscape Lighting Application Circuit - 4 -

  5. Application Example (High Voltage) HighVoltage App.(1) HighVoltage App.(2) ☞ VS = More than 400V Enable ☞ ILED = 600/RFB [mA] ☞ VS = More than 400V Enable ☞ ILED = 600/RFB [mA] - 5 -

  6. Application Example (High Voltage) HighVoltage App.(3) Fashionable Lighting ☞ Improve the device PD Problem ☞ Fashionable LED Lighting - 6 -
