XD33063 – DC-DC Converter – Xinluda

The Xinluda XD33063 is a monolithic step-up/step-down/inverting DC-DC switching regulator (MC33063/MC34063-compatible) in a DIP-8 package, operating from 3V to 40V with a 1.5A peak output switch.

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.

Key Features

• Monolithic DC-to-DC converter control circuit (33063/34063 series)

• Peak output switch current: up to 1.5A
• Oscillator switching frequency up to 100kHz
• Supports step-up (boost), step-down (buck), and voltage-inverting topologies
• On-chip temperature-compensated reference (2% precision)
• Active current-limit circuitry for short-circuit and overcurrent protection
• Operating temperature range: -40°C to +85°C
• DIP-8 through-hole package

Applications

• Low-power buck and boost DC-DC power supplies
• Battery-powered and portable equipment
• Negative-voltage / inverting supply generation
• Consumer electronics and appliance power rails
• Industrial control and instrumentation supplies
• Drop-in replacement for legacy MC33063/MC34063 designs

Why Source XD33063 from Pacific Component Xchange

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.
