S8200
Linear LED Driver IC
◈ Description
The S8200 is an integrated adjustable constant-current source, driving loads up to 150mA, The output current level
can be adjusted via an external resistor. The integrated SHDN input of the S8200 permits LED brightness
regulation by pulse width modulation (PWM), with the SHDN input, the LED brightness can be regulated via duty
cycle. Also, SHDN low sets the S8200 in sleep mode, the SHDN pin also can be used as an enable input.
This discrete integration technology eliminates individual components by combining them into a single package,
which results in a significant reduction of both system cost and board space. The device is a small surface mount
package (SOT-25)
◈ Features
• Supplies stable bias current for LEDs
• LED drive current adjustable via single external resistor (Max 150mA)
• Low Cost, Low External Parts Count
• Small Surface-Mount SOT-25 Package
• Halogen-Free Package is Available

◈ Design Consideration
1) Calculation for RFB
- RFB = 0.6V / ILED
2) Calculation for Vdrop
- Vdrop = VCC – VLED
3) Calculation for Power Dissipation on the S8200
-PD1 = (Vdrop – VFB) x ILED
-PD2 = VCC x IQ
-PD(total) = PD1 + PD2
4) If does not use an Dimming function, connect SHDN Pin with the ground.
