GENERAL DESCRIPTION
The XC9250/XC9251 series are 30V operation step-down DC/DC converter ICs with an internal driver transistor. The internal Nch driver
transistor is driven by bootstrap to achieve a stable, high-efficiency power supply up to an output current of 2.0A. Low ESR capacitors such as
ceramic capacitors can be used for the load capacitor (CL).
A 0.8V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.2V to 12.0V using external
resistors (RFB1, RFB2).
300kHz or 500kHz can be selected for the switching frequency. The generation of unneeded noise can be suppressed by synchronizing to an
external CLK in a range of ±25% of the free running frequency using the SYNC pin. In automatic PWM/PFM control, the IC operates by PFM
control when the load is light to achieve high efficiency over the full load range from light to heavy.
The soft start time can be set as desired by adding an external capacitance to the SS pin.
With the built-in UVLO function, the driver transistor is forced OFF when input voltage becomes 4.5V or lower.
Internal protection circuits include over current protection, integral latch protection, short-circuit protection, and thermal shutdown circuits to
enable safe use.
