S8300
Linear LED Driver IC
◈ Description
The S8300 is an integrated adjustable constant-current source, driving loads up to 600mA. The output
current level can be adjusted via an external resistor(RFB). The integrated SHDN input of the S8300P
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 S8300 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.

◈ Typical Applications
S8300
<APP4. High Voltage Operation of S8300P (1) >
<APP5. High Voltage Operation of S8300P (2) >
For operation in excess of S8300 specified maximum voltage (VCC & VOUT) of 25V, one way is
to connect a sufficient number of LEDs between the power supply voltage and the DC input of
the VCC&VOUT such that the voltage seen at pin(VCC & VOUT)is less than 25V.
That is to say, use additional LEDs to drop the voltage fed to the S8300 below its maximum
rating, in the usual way. Refer to APP4,5 Note that the exact number of diodes required will
depend on the supply voltage VCC and output voltage VOUT ,the voltage drops across the
particular LEDs being used. (Red, Blue and White LEDs have different forward voltage drop.)
Use enough LEDs such that voltage at pin(VCC & VOUT) of S8300 is < 25V
※ Caution : When VS uses to exceed 25V, Dimming functions the use is impossible.
