XC9101 - PWM Controlled Step-Up DC/DC Controller

Description

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.

Features

XC9101 series is Not Recommended for New Designs. XC9101 Series PWM Controlled Step-Up DC/DC Controller ETR0403_006a ■GENERAL DESCRIPTION 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 increments 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 using 2 external resistors.
