MT7004B
MT7004B is Boost LED Driver manufactured by Maxic Technology.
DESCRIPTION
The MT7004B is a Boost LED driver for driving up to 39 LEDs (3-series and 13-parallel) from a 5V system rail. The MT7004B uses current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 110m V feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The MT7004B includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload.
