The XL9910 from Xinluda is a high-voltage, open-loop, current-mode control LED driver controller designed for single-switch step-down (buck) LED lighting applications. With an integrated 8.0V-450V linear regulator, the XL9910 operates directly from a wide range of input voltages, eliminating the need for a separate low-voltage auxiliary supply. The device can be configured for either constant-frequency or constant off-time operation, and it requires only three external components in addition to the power stage to deliver a well-controlled LED current.
Integrated PWM and linear dimming inputs make the XL9910 a flexible choice for dimmable LED fixtures. Because it uses open-loop current-mode control, the controller achieves excellent output current regulation without the need for loop compensation.
The XL9910 is a specialized LED driver controller with limited authorized-distributor availability, which can make it difficult to source through conventional channels. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs and optocouplers. We help engineers and procurement teams secure parts like the XL9910 when mainstream stock is unavailable.
Our team prioritizes authenticity and supply-chain integrity, sourcing from vetted partners and supporting global shipping to keep your production lines running. Whether you need a single reel or a large production volume, we can help.

The XL9910 is a high-voltage, open-loop, current-mode control LED driver controller from Xinluda, designed for single-switch step-down (buck) LED lighting applications. It integrates a wide-range linear regulator and supports both PWM and linear dimming.
The XL9910 includes an integrated linear regulator that allows operation from 8.0V up to 450V, so it can run from a wide range of input voltages without a separate low-voltage supply.
The XL9910 is supplied in a RoHS-compliant SOP-8 surface-mount package.
Yes. The XL9910 provides a PWM dimming input that accepts a 0-100% duty cycle at frequencies up to several kHz, plus a 0-250mV linear (analog) dimming input for adjusting LED current.
The XL9910 operates over a switching frequency range of 20kHz to 120kHz and can be configured for constant-frequency or constant off-time operation.
The XL9910 has limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find power-management ICs like the XL9910. Submit an RFQ and our team will work to secure the part for you.
