The XL1682 is a single-stage power-factor-correction (PFC) AC-DC LED offline driver controller manufactured by Xinluda Information Technology Co., Ltd. Using primary-side regulation (PSR) and pulse-frequency-modulation (PFM) control, the XL1682 delivers tight constant-current (CC) output regulation directly from the AC line without the need for a secondary-side optocoupler or feedback network. This single-stage architecture reduces component count, board area, and bill-of-materials cost while maintaining a high power factor and low total harmonic distortion (THD) across the universal AC input range, and helps designs meet IEC 61000-3-2 harmonic standards, making it well suited to cost-sensitive LED lighting designs.
Housed in a compact SOP-8 package, the XL1682 integrates accelerated startup with low startup and operating current, plus a robust suite of protection functions including open-load and reload detection, output overvoltage protection (OVP), short-circuit protection (SCP), and overcurrent protection (OCP). It is rated for an industrial operating temperature range of -40°C to +85°C and is supplied RoHS-compliant on tape and reel.
The XL1682 is a specialized Xinluda LED-driver IC with limited authorized-distributor availability, which can make it difficult to source through mainstream channels – especially for production volumes or end-of-life and obsolete buys. Pacific Component Xchange is an independent distributor focused on hard-to-find power-management ICs and optocouplers, with a global supplier network built to locate scarce and allocated parts like the XL1682.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability processes designed to protect your supply chain from counterfeit and substandard components. We offer worldwide shipping and responsive, quote-based pricing tailored to your quantity and lead-time requirements.

The XL1682 is a single-stage power-factor-correction (PFC) AC-DC LED offline driver IC from Xinluda. It uses primary-side regulation (PSR) and PFM control to provide tight constant-current LED output with high power factor and low THD, without requiring an optocoupler.
The XL1682 is supplied in an SOP-8 package, RoHS compliant, on tape and reel (2,500 pieces per reel).
No. The XL1682 uses primary-side regulation (PSR), so it achieves constant-current output regulation without a secondary-side optocoupler or feedback network, reducing component count and cost.
The XL1682 integrates output overvoltage protection (OVP), short-circuit protection (SCP), overcurrent protection (OCP), and open-load and reload detection.
The XL1682 is rated for an industrial operating temperature range of -40 C to +85 C.
Yes. The XL1682 has limited authorized-distributor availability. Pacific Component Xchange is an independent distributor specializing in hard-to-find power-management ICs and can source the XL1682 through its global supplier network. Submit an RFQ for current availability and quote-based pricing.
The XL1682 is designed for single-stage power-factor-corrected LED lighting power supplies, including LED bulbs, tubes, downlights, and other cost-sensitive AC-DC constant-current lighting drivers.
