SN8500D
Switching Type (Buck) LED Driver IC
◈ Description
The SN8500D is a high power PWM LED driver IC using a buck converter topology that is capable of driving up
to 1.5A of output current. it operates from an input voltage range of 3Vdc to 40Vdc and generates a regulated
programmable constant output current for high power LEDs. external resistor controlled the maximum output
current to single LED or a LED string.
◈ Features
• Operation from 3.0V to 40V input.
• Low Standby Current
• High efficiency
• Output Switch Current to 1.5A
• Halogen-Free Package is Available
◈ Application
• Automotive and Marine Lighting
• High Power LED Driver
• Constant Current Source
