HBLED Driver

  • DC/DC and AC/DC driver ICs
  • For general lighting applications such as MR16 Accent lighting
  • Integrated and external MOSFET based solutions
  • Robust built in protections for extended life operation
  • Non-Dimmable and Dimmable (Analog, PWM and Switch)
  • Extended operating temperature range
