The Xinluda XD34063 is a monolithic DC-DC switching regulator control circuit, functionally compatible with the industry-standard MC34063. It integrates the core building blocks required to construct a complete switch-mode power converter, including a temperature-compensated voltage reference, a comparator, a duty-cycle-controlled oscillator with active current-limit sensing, a driver, and a high-current output switch. With a wide input voltage range and configurable output, the XD34063 supports buck (step-down), boost (step-up), and inverting power-supply designs using a minimum of external components.
The XD34063 is a drop-in equivalent for the MC34063, TD34063, and KA34063, making it a practical replacement for legacy and end-of-life designs that rely on the 34063 architecture. It is offered in a through-hole DIP-8 package, with a surface-mount SOP-8 variant available under the XINLUDA XL34063 designation.
The XD34063 is a hard-to-find part with little to no authorized-distributor availability. Pacific Component Xchange specializes in sourcing scarce, obsolete, and end-of-life power-management ICs like the XD34063 for engineers and buyers who need a reliable supply. Every order is backed by our authenticity and quality-assurance process to protect your production line against counterfeit and substandard parts. With global shipping and a responsive sourcing team, we help you keep MC34063-based designs in production. Request a quote (RFQ) today and our team will confirm availability, lead time, and pricing for the quantity you need.
The XD34063 is a monolithic DC-DC switching regulator control circuit from Xinluda. It is functionally compatible with the industry-standard MC34063 and can be configured for step-down (buck), step-up (boost), or voltage-inverting power-supply designs.
Yes. The XD34063 is documented as an equivalent to the MC34063, TD34063, and KA34063, making it a practical drop-in replacement for designs built around the 34063 architecture.
The XD34063 accepts an input voltage from 3 V to 40 V and provides an adjustable output from approximately 1.25 V to 28 V, depending on the external resistor divider and topology used.
The XD34063 is offered in a through-hole DIP-8 package. A surface-mount SOP-8 version is available from Xinluda under the XL34063 part designation.
The XD34063 has limited authorized-distributor availability, so Pacific Component Xchange handles it as an RFQ product. Submit a quote request and our sourcing team will confirm current stock, lead time, and pricing for your required quantity.
Yes. As an independent distributor specializing in hard-to-find power-management ICs, Pacific Component Xchange applies authenticity and quality-assurance checks to help protect your supply chain against counterfeit components.
