GS5901 - Boost for White LED Driver

General Description

The GS5901 is a high frequency, asynchronous boost converter.

The internal MOSFET can support up to 8 White LEDs for backlighting and OLED power application, and the internal soft start function can reduce the inrush current.

Key Features

  • 2.5V to 5.5V operating input voltage range.
  • Drives up to 8 series White LEDs.
  • 1.0MHz Fixed Switching Frequency.
  • Wide range for PWM dimming (200Hz to 200KHz).
  • Internal 1.4A switching curre.

GS5901 1.4A, Boost for White LED Driver Product Description The GS5901 is a high frequency, asynchronous boost converter. The internal MOSFET can support up to 8 White LEDs for backlighting and OLED power application, and the internal soft start function can reduce the inrush current. The GS5901 uses current mode, 1.0MHz fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. The OVP pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The GS5901 includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage in the event of an output overload. The driver is available in small SOT23-6L & TSOT-23-6L packages.
