GR5401A Overview
The GR5401A 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 GR5401A uses current mode, 1.0MH Z fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor.
