XC9223/XC9224 Series
1A Driver
Transistor Built-In Step-Down DC/DC Converters
ETR0509_017
■GENERAL DESCRIPTION
☆Green Operation Compatible
The XC9223/XC9224 series are synchronous step-down DC/DC converters with a 0.
21Ω (TYP.
) P-channel driver
transistor and
a synchronous 0.
23Ω (TYP.
) N-channel switching
transistor built-in.
A highly efficient and stable current can be supplied up to 1.
0A
by reducing ON resistance of the built-in
transistor.
With a high switching frequency of 1.
0MHz or 2.
0MHz, a small inductor is
selectable; therefore, the XC9223/XC9224 series are ideally suited to applications with height limitation such as HDD or space-
saving applications.
