XC9201 Series
PWM Controlled Step-Down DC/DC Controllers
ETR0502_004
■GENERAL DESCRIPTION
The XC9201 series are step-down 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 3.0A. With output voltage fixed internally, output voltage is selectable in 100mV increments (semi-custom) within a 1.2V ~ 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.
