The XL3845 is a high-performance, fixed-frequency current-mode PWM controller manufactured by Xinluda (Shenzhen Xinluda Information Technology). Belonging to the widely deployed UCx84x / UC3845 controller family, the XL3845 is designed to implement off-line and DC-to-DC fixed-frequency current-mode control schemes with a minimum of external components. It is supplied in a compact SOP-8 surface-mount package (the Xinluda datasheet also documents a DIP-8 option) and provides the load-response and line-regulation advantages of current-mode control over voltage-mode designs.
The XL3845 is a specialty Xinluda controller with limited authorized-distributor availability, which makes consistent, verified supply a challenge for production and repair builds. 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 the XL3845 and its UCx84x-family equivalents when standard channels come up short.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability processes designed to protect your bill of materials from counterfeit and substandard parts. We offer global shipping and flexible quantities for prototype through production volumes.
Because the XL3845 is a request-for-quote item, contact Pacific Component Xchange today to request a quote on current availability, lead time, and pricing. Submit your RFQ and our sourcing team will respond promptly with verified stock options.
The XL3845 is a fixed-frequency, current-mode PWM controller from Xinluda, supplied in an SOP-8 package (a DIP-8 option is also documented). It belongs to the UCx84x / UC3845 controller family and is used to control off-line and DC-to-DC switch-mode power supplies with cycle-by-cycle current limiting.
Yes. The XL3845 is part of the UCx84x family and is pin-function compatible with the industry-standard UC3845 / TL3845. Like the UC3845, it has a maximum duty cycle limited to 50%. Always confirm against the datasheet for your specific design.
Pacific Component Xchange lists the XL3845 in the SOP-8 (8-pin small-outline) surface-mount package. The Xinluda datasheet also documents a DIP-8 through-hole option.
Per the Xinluda XL3845 datasheet, the start-up (turn-on) threshold is typically 8.8 V (specified range 8.0 to 9.0 V) and the minimum operating voltage is typically 8.0 V (range 7.0 to 8.3 V). Confirm against the datasheet for your design.
The Xinluda datasheet specifies a maximum operating frequency up to 500 kHz, a low typical start-up current of 60 uA, and a high-current push-pull (totem-pole) output capable of up to 1 A of drive current for a power MOSFET gate.
