S8350D
Linear LED Driver IC
◈ Description
The S8350D is an integrated adjustable constant-current source, driving loads up to 1200mA. The output current
level can be adjusted via an external resistor. The integrated SHDN input of the S8350D 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 S8350D 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.
◈ Features

◈ Typical Applications

<APP4. High Voltage Operation of S8350D (1) >
<APP5. High Voltage Operation of S8350D (2) >
For operation in excess of S8350D 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 S8350D 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 S8350D is < 25V.
※ Caution : When VCC uses to exceed 25V, Dimming functions the use is impossible.
