Product Description


18V, 500mA Synchronous Step-Down PWM DC/DC Converter

The XC9263 is a synchronous step-down DC/DC with P-Ch High Side Switch to ensure low voltage operation with 100% max duty ratio. It can operate from 3.0V~18.0V and deliver loads up to 500mA making it an ideal replacement for inefficient linear regulators used in many industrial applications.

The XC9263 also works with Low ESR ceramic capacitors and comes with a choice of three switching frequencies, adjustable soft start and a power good output.


Available in SOT-25 and the ultra small USP-6C package, measuring only 2.0 x 1.8 x 0.6mm an extremely small DC/DC circuit can be implemented with a minimal number of external components.


The XC9263 includes Over Current and VOUT shortcircuit protection circuits, the designer can select either a Latch or Auto-restart configuration depending on the application requirements.
