The XD3846 is a fixed-frequency, current-mode PWM controller manufactured by Xinluda Information Technology Co., Ltd. Supplied in a through-hole DIP-16 package, the XD3846 is designed for current-mode-controlled switched-mode power supplies and belongs to the widely used UC3846 / SG3846 controller family. It delivers the core building blocks needed to implement fixed-frequency current-mode control with a minimum of external components, while improving line regulation and load-transient response.
The XD3846 is a specialized PWM controller with little to no authorized-distributor stock, which makes it a challenge for buyers maintaining or building current-mode power-supply designs. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs and can help you secure the XD3846 when conventional channels come up empty.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability processes to protect against counterfeit parts. We support global shipping and flexible quantities, whether you need a handful of units for a repair or volume for a production run. Because this is a Request-For-Quote part, contact Pacific Component Xchange today to request a quote on the XD3846 and let our sourcing team locate the stock you need.
The XD3846 is a fixed-frequency, current-mode PWM controller from Xinluda, supplied in a DIP-16 package. It provides dual 500mA peak totem-pole outputs, 500kHz operation, and a +/-1% bandgap reference for current-mode switched-mode power supplies.
Yes. The XD3846 belongs to the industry-standard UC3846 / SG3846 current-mode PWM controller family, sharing the same core feature set and 16-pin layout.
The XD3846 is offered in a 16-pin through-hole DIP-16 package. Xinluda also offers a surface-mount (SOP-16) version under a related part number.
The XD3846 provides current-mode control with automatic feedforward compensation, automatic symmetry correction in push-pull configurations, a differential current-sense amplifier with wide common-mode range, and parallel operation capability for modular power systems.
It includes programmable pulse-by-pulse current limiting, undervoltage lockout (UVLO), soft-start, and double-pulse suppression.
Yes. The XD3846 is a hard-to-find, Request-For-Quote part with limited authorized-distributor stock. Pacific Component Xchange specializes in sourcing such components. Submit an RFQ and our team will work to locate the part and provide a quote.
