■GENERAL
DESCRIPTION
The XC6371/XC6372 series is a group of PWM controlled and PWM/PFM controlled step-up DC/DC converters. The built-in
1.4Ω switching transistor type enables a step-up circuit to be configured using only three components, a coil, a diode, and a
capacitor.
Output voltage can be selectable in the range from 2.0V to 7.0V in increments of 0.01V (accuracy:±2.5%). Oscillation
frequency is also selectable from 50kHz, 100kHz, and 180kHz (accuracy:±15%) for the XC6371 and the XC6372 series.
Soft-start time is internally set and offers protection against in-rush currents when the power is switched on and prevents
voltage overshoot. Packages with CE (chip enable) pin are also available which can reduce the IC power consumption
during during stand-by mode.
The XC6371 series is the standard PWM controlled products. The control of the XC6372 series switches from PWM to PFM
control during light loads when automatically switching is selected and the series is highly efficient from light loads to large
output currents.
