XL9910 SOP-8 LED driver IC

PublishTime：2021-05-19

XL9910 is an open loop, current mode control, LED driver IC. This IC can be programmed to operate in either a constant frequency or constant off-time mode. It includes an 8.0 - 450V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. XL9910 includes a PWM-dimming input that can accept an external control signal with a duty ratio of 0 - 100% and a frequency of up to a few kilohertz. It also includes a 0 - 250mV linear dimming input which can be used for linear dimming of the LED current.
XL9910 is ideally suited for buck LED drivers. Since the XL9910 operates in open loop current mode control, the controller achieves good output current regulation without the need for any loop compensation. PWM dimming response is limited only by the rate of rise and fall of the inductor current, enabling very fast rise and fall times. XL9910 requires only three external components, apart from the power stage, to produce a controlled LED current. This makes XL9910 an ideal solution for low cost LED drivers.
