18V, 500mA Synchronous Step-Down PWM/PFM DC/DC Converter
The XC9264 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 XC9264 is designed for very high efficiencies at low output loads, with low quiescent current and automatic PWM/PFM mode.
The XC9264 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 XC9264 includes Over Current and VOUT shortcircuit protection circuits, the designer can select either a Latch or Auto-restart configuration depending on the application requirements.
