XC9250/XC9251 Series
ETR05023-004
30V Driver
Transistor Built-In Step-Down DC/DC Converters
â– 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.
