Product Description
18V 0.5A Synchronous Step-Down DC/DC Converter
The XD9263 series are synchronous step-down DC/DC converter ICs. The XD9263 series has an operating voltage range of 3V~18V, a switching frequency of 2.2 MHz and it can support 500mA as an output current with high-efficiency. Compatible with Low ESR capacitors such as ceramic capacitors for the output capacitor.
0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.0V to 15.0V using external resistors.
The XD9263 has a fixed internal Soft Start time which is 1.0ms (TYP.), additionally the time can be extended by using an external resistor and capacitor.
UVLO, over current protection, short-circuit protection and thermal shutdown are embedded, and they secure safe operation. As an option, timer latch off over current protection (Integral Latch Method) can be selected.
