MBI6653 - 1A Dimmable LED Driver

General Description

MBI6653 is a step-down constant-current high-brightness LED driver to provide a cost-effective design solution for interior/exterior illumination applications.

It is designed to deliver constant current to light up high power LED with only 6 external components.

Key Features

  • 6~36V wide input voltage range.
  • Maximum 1A constant output current.
  • Patented fixed frequency analog dimming control - PWM-controlled brightness modulation - DC voltage-controlled brightness modulation.
  • 97% efficiency @ input voltage 12V, 350mA, 3-LED.
  • Hysteretic PFM operation eliminates external compensation design.
  • Integrated power switch with 0.3ohm low Rds(on).
  • Full protections: UVLO/ Start-Up/OCP/ Thermal/ LED Open-/ Short-Circuit.
  • Only 5 external com.
