Power LED Driver IC
◈ Description
The S8100 is a PWM high-efficiency LED driver control IC. It allows efficient operation of High Brightness (HB)
LEDs. The S8100 is capable to drive high current, high brightness LEDs up to 1.0 A by using additional external
output stages as Power MOSFET. The S8100 provides a low-frequency PWM dimming input that can accept
an external control signal with a duty ratio of 0-100% and a frequency of typical 100Hz. The output current
can be programmed between a few milliamps and up to more than 1.0A. The device is a small surface mount
package (SOT-26)
◈ Features
• Vcc : 2.5V~18V
• Low Quiescent Current : 0.8mA
• Output Source current : 0.15mA
• PWM Dimming with pull-up resistor control
• Stability compensation with 0.1µF ceramic capacitance
• Small Surface-Mount SOT-26 Package
• Halogen-Free Package is Available
