XC9263/XC9264Series

18V Operation 0.5A Synchronous Step-Down DC/DC Converters

ETR05047-006

■GENERAL DESCRIPTION

The XC9263/XC9264 series are 18V operation synchronous step-down DC/DC converter ICs with a built-in high-side / low-side

driver transistor. The XC9263/XC9264 series has operating voltage range of 3.0V~18.0V and it can support 500mA as an output

current with high-efficiency. Compatible with Low ESR capacitors such as ceramic capacitors for the load capacitor (C_L).

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 (R_FB1, R_FB2).

500kHz or 1.2MHz or 2.2MHz can be selected for the switching frequency. In PWM/PFM automatic switchover control, IC can

change the control method between PWM and PFM based on the output current requirement and as a result IC can achieve high

efficiency over the full load range.

XC9263/64 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.

With the built-in UVLO function, the driver transistor is forced OFF when input voltage goes down to 2.7V or lower.

The output state can be monitored using the power good function.

Over current protection and thermal shutdown are embedded and they secure a safety operation.
