LED Drivers

PWM boost controllerLED constant currentExternal MOSFETSOP-8Adjustable frequency

OC6781 is an SOP-8 PWM boost controller for regulating current through high-power or series-connected LEDs using an external MOSFET.

Best for

  • Boost-driven high-power LED strings
  • Battery-powered LED lighting
  • LED backlight applications

Avoid if

  • A complete LED driver with integrated power MOSFET is required
  • Verified RoHS, REACH, lifecycle, or qualification data is mandatory

Check before use

  • Confirm output voltage and MOSFET voltage margin
  • Calculate peak inductor current at minimum input voltage
  • Set OVP divider and LED current feedback resistor
  • Confirm sourcing and compliance status
