■GENERAL DESCRIPTION
☆GreenOperation-compatible
The XC9257/XC9258 series is a group of synchronous-rectification type DC/DC converters with a built-in P-channel MOS driver
transistor and N-channel MOS switching
transistor, designed to allow the use of ceramic capacitors.
Output voltage is internally set in a range from 0.
8V to 3.
6V (accuracy: ±2.
0%) increments of 0.
05V.
The device provides a high efficiency, stable power supply with an output current of 1.
0A to be configured using only a coil and two capacitors connected externally.
Oscillation frequency is set to 1.
2MHz or 6.
0MHz can be selected ...
