XL33063 – DC-DC Converter – Xinluda

The Xinluda XL33063 is a monolithic DC-to-DC converter control IC supporting step-down (buck), step-up (boost), and voltage-inverting topologies with a 3V-40V input range and 1.5A peak switch current in an SOIC-8 package.

The XL33063 from Xinluda is a monolithic DC-to-DC converter control circuit, pin-compatible with the classic 33063/MC33063A family. It integrates the primary functions required to build step-down (buck), step-up (boost), and voltage-inverting switching power supplies using a minimum number of external components, including a temperature-compensated reference, comparator, on-chip oscillator with active current-limit circuitry, driver, and a high-current output switch. Its wide operating voltage range and built-in protection make it a versatile, low-cost building block for compact power-management designs.
