XC6371/XC6372/XC6373Series

ETR0402_002

PWM Controlled Step - Up DC/DC Contorollers/Convereters

☆GO-Compatible

■GENERAL DESCRIPTION

The XC6371/6372/6373 series are 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 100mV (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. 5 pin packages, which are provided with either a CE (chip enable) function that reduces power

consumption during shut-down mode, or a VDD pin (separated power and voltage detect pins) are available.

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. Since the XC6373 series is a low noise, it is suitable for a wireless circuit. Also the series is particularly

suited for use with pager applications because oscillation frequency is set at 30kHz (±20%) so as to attain the lowest

consumption current possible.
