MBI6657 - 1A Dimmable LED Driver

General Description

MBI6657 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 5 external components.

Key Features

  • 6~40V wide input voltage range.
  • Maximum 1A constant output current (1.2A for MBI6657GSB).
  • PWM/DC input for dimming control.
  • Hysteretic PFM operation eliminates external compensation design.
  • Integrated power switch with 0.25-ohm low Rds(on).
  • Full protections: Thermal Foldback/ Thermal Shutdown/ Schottky Diode Short/ LED Open/Short-Circuit.
  • Only 5 external components required.
  • Package MSL Level: 3 Small Outline Transistor GST: SOT-23-6L Product Descriptio.
