The Xinluda XD33063 is a monolithic control circuit that integrates the primary building blocks required for DC-to-DC converters. Part of the industry-standard 33063/34063 family, it combines a temperature-compensated reference, a comparator, a duty-cycle-controlled oscillator with active current-limit, a driver, and a high-current output switch in a single 8-pin package. The XD33063 is purpose-built for step-down (buck), step-up (boost), and voltage-inverting applications using a minimum of external components.
The Xinluda XD33063 has limited authorized-distributor stock, making it a challenging part to procure for production and repair builds. Pacific Component Xchange specializes in sourcing hard-to-find and end-of-life power-management ICs like the XD33063. As an independent distributor, we offer authenticity verification, global shipping, and access to supply channels that mainstream catalog distributors cannot. Whether you need a single tube for a prototype or volume quantities for a production run, our team can locate and qualify the parts you need.

The XD33063 is a monolithic DC-to-DC converter control circuit from Xinluda. It belongs to the industry-standard 33063/34063 family and supports step-up, step-down, and voltage-inverting power supply designs in a DIP-8 package.
Yes. The XD33063 is part of the 33063/34063 series, sharing the same architecture, pinout, and core electrical characteristics, making it a drop-in alternative in most legacy MC33063/MC34063 designs.
The XD33063 operates over a wide input voltage range of 3V to 40V.
The XD33063 provides a peak output switch current of up to 1.5A and an oscillator/switching frequency up to 100kHz.
This listing covers the DIP-8 through-hole package.
The XD33063 has limited authorized-distributor availability. Pacific Component Xchange sources it through independent supply channels, so pricing and lead time are confirmed per quote. Submit an RFQ for current availability.
