The XC9101 series are step-up multiple current and voltage feedback DC/DC controller ICs. Current sense, clock frequencies and amp feedback gain can all be externally regulated. A stable power supply is possible with output currents of up to 1.5A. With output voltage fixed internally, VOUT is selectable in 0.1V steps within a 2.5V - 16.0V range ( 2.5%). For output voltages outside this range, we recommend the FB version which has a 0.9V internal reference voltage. Using this version, the required output voltage can be set-up using 2 external resistors. Switching frequencies can also be set-up externally within a range of 100~600 kHz and therefore frequencies suited to your particular application can be selected.
