The Xinluda XL2845 is a high-performance, fixed-frequency current-mode PWM controller designed for off-line and DC-to-DC switching power supply applications. Part of Xinluda’s XL28xx controller series, the XL2845 follows the well-established pin-out and functional behavior of the industry-standard UC2845/UC3845 current-mode controllers, making it a practical drop-in alternative for cost-sensitive and supply-constrained designs. It is supplied in a compact surface-mount SOP-8 package.
As a “45”-suffix member of the family, the XL2845 features an internally limited maximum duty cycle of approximately 50%, which makes it well suited to forward and flyback converter topologies that require duty-cycle clamping. Consistent with the UC2845/UC3845 architecture it follows, the controller is built around cycle-by-cycle current-mode control and a gate-drive output stage capable of driving external power MOSFETs in compact converter designs.
The XL2845 is a Xinluda-branded part with limited authorized-distributor coverage, which can make it difficult to procure through mainstream channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and optocouplers. We help engineers and buyers secure XL2845 controllers and equivalent UC2845/UC3845-family parts even when standard supply lines are dry.
Every order is backed by our commitment to authenticity, inspection, and traceability, with global shipping to keep your production lines moving. Whether you need a single reel for a prototype run or volume quantities for production, our team can source the XL2845 to your requirements. Request a quote (RFQ) today and our sourcing specialists will respond with availability, lead time, and pricing for the Xinluda XL2845.
The XL2845 is a high-performance fixed-frequency current-mode PWM controller from Xinluda, supplied in an SOP-8 package. It is intended for off-line AC-DC and DC-DC switching power supply designs and follows the functional behavior of the industry-standard UC2845/UC3845 controller family.
Yes. The XL2845 belongs to Xinluda's UC284x-style controller series and is functionally aligned with the UC2845/UC3845. Like other 45-suffix controllers in this family, it provides an internally limited maximum duty cycle of approximately 50%. As with any cross, always confirm pin-out, UVLO thresholds, and timing against your design before substitution.
Both are current-mode PWM controllers from Xinluda. The XL2845 limits maximum duty cycle to approximately 50%, mirroring the UC3845-versus-UC3843 distinction in the standard family. As always, confirm the exact duty-cycle and timing behavior against each part's documentation before substitution.
Pacific Component Xchange lists the XL2845 in the SOP-8 surface-mount package, which is the standard offering for this Xinluda controller per the manufacturer's PWM controller catalog.
Per Xinluda's PWM controller documentation, the XL2845 operates over a VCC supply range of approximately 8.2 V to 30 V, with oscillator operation supported up to 500 kHz.
Yes. The XL2845 has limited authorized-distributor availability, and that is exactly where Pacific Component Xchange helps. As an independent distributor specializing in hard-to-find power-management ICs, we can source the XL2845 on request. Submit an RFQ and we will respond with availability, lead time, and pricing.
