Cxsd6101f is a low voltage, constant current, high efficiency high brightness LED driver. Cxsd6101f is especially suitable for wide input voltage range applications, with input voltage range from 5.5V to 36V, and cxsd6101f has high rejection ratio for input voltage. The cxsd6101f uses a built-in power switch with low on resistance, which simplifies the peripheral circuit of the chip. It only needs a few external components to realize the function of voltage reduction and constant current drive, and can realize the function of brightness control through the dim pin. The cxsd6101f sets the output current through an external resistor, and its built-in power MOS tube achieves a current accuracy of ?4% for high-end current detection. Because of the hysteresis control, cxsd6101f has a very fast response speed to load transients, with a maximum operating frequency of 1MHz
