QX5246F high-end current detection high-brightness LED driver

QX5246F is a buck, constant current, high efficiency and high brightness LED driver.

The QX5246F is particularly suitable for applications with a wide input voltage range. The input voltage range is from 5.5V to 36V, and the QX5246F has a high rejection ratio to the input voltage.

The QX5246F uses a built-in low on-resistance power switch tube, which simplifies the peripheral circuit of the chip. Only a few external components are needed to achieve the step-down, constant current drive function, and the brightness control function can be realized through the DIM pin.

QX5246F sets the output current through an external resistor. Its built-in power MOS tube, high-end current detection achieves a current accuracy of ± 4%.

Due to the hysteresis control method, the QX5246F has a very fast response speed to load transients, and the maximum operating frequency can reach 1MHz.

QX5246F is available in ESOP8 package.
