XC9263/XC9264 Series
ETR05047-001
18V Operation 0.5A Synchronous Step-Down DC/DC Converters
■GENERAL DESCRIPTION
The XC9263/64 series are 18V operation synchronous step-down DC/DC converter ICs with a built-in high-side / low-side driver
transistor. The XC9263/64 series has operating voltage range of 3.0V～18.0V and it can support 0.5A as an output current with
high-efficiency. Compatible with Low ESR capacitors such as ceramic capacitors for the load capacitor (CL).
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 (RFB1, RFB2).
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, short-circuit protection and thermal shutdown are embedded and they secure a safety operation.
