MT9201 - High Efficiency Boost White LED Driver

General Description

The MT9201 is a step-up converter designed for driving up to 7 series white LEDs from a single cell Lithium Ion battery.

The MT9201 uses current mode, fixed frequency architecture to regulate an LED current, which is measured through an external current sense resistor.

Key Features

  • High Efficiency: Up to 90%.
  • 1.2MHz Constant Frequency Operation.
  • Integrated internal Power MOSFET.
  • Drives up to 7 Series WLEDs.
  • Low 200mV Feedback Voltage.
  • Soft-start/Dimming with wide Frequency Range.
  • UVLO, Thermal Shutdown.
  • Internal Current limit.
  • Over Voltage Protection.
  • Small LC Filter.
  • Minimize the External Component.
