The Xinluda XL2843 is a high-performance current-mode PWM controller supplied in a compact SOP-8 package. It belongs to Xinluda’s UC284x/UC384x-compatible PWM controller line and is functionally aligned with the widely used UC2843 industry standard, making it a practical second-source option for off-line and DC-DC switch-mode power supply designs. With an operating supply (VCC) range of 8.2 V to 30 V, current-mode control with cycle-by-cycle current limiting, and an oscillator that supports switching frequencies up to 500 kHz, the XL2843 is well suited to compact, cost-sensitive power converter platforms.
The XL2843 is a hard-to-find part with little to no authorized-distributor stock, which can stall production schedules and BOM completion. Pacific Component Xchange is an independent distributor specializing in scarce and obsolete power-management ICs and optocouplers. We help engineers and buyers locate, qualify, and secure components like the XL2843 even when standard channels show zero availability.
Every order is backed by our commitment to authenticity and supply-chain integrity, with inspection and verification processes designed to protect you from counterfeit or substandard parts. We support global shipping and flexible quantities, from prototype runs to production volumes. Because this is a request-for-quote item, contact Pacific Component Xchange today to submit an RFQ for the XL2843 and our sourcing team will respond with current availability, lead time, and pricing.
