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.
