XL34063 – DC-DC Converter – Xinluda

The Xinluda XL34063 is a monolithic DC-DC converter control IC in an SOP-8 package, part of the MC34063 family. It supports step-up (boost), step-down (buck), and inverting topologies with a wide 3V to 40V input range and an internal switch rated up to 1.5A.

The Xinluda XL34063 is a monolithic DC-DC converter control IC belonging to the widely adopted MC34063 family of switching regulators. Housed in a compact SOP-8 surface-mount package, it integrates a temperature-compensated reference, a comparator, a PWM oscillator with active current-limit circuitry, a driver, and a high-current output switch, enabling step-up (boost), step-down (buck), and voltage-inverting power-supply designs with a minimal external component count.

Engineered for broad input flexibility, the XL34063 accepts an input (supply) voltage from 3V to 40V. The output voltage is adjustable via an external resistor divider referenced to the device’s internal 1.25V reference. The internal output switch is rated for currents up to 1.5A, and the oscillator operates at frequencies up to 100kHz, making the part well suited to cost-sensitive embedded and industrial power applications.
