Description

The XC6371 series is a group of PWM controlled step-up DC/DC converters. The XC6371 series employs CMOS process and laser trimming technologies so as to attain low power and high accuracy. On-chip proprietary phase compensation and slow start-up circuits ensure excellent transient response and improved performance.

Output voltage of XC6371 can be selected from 2.0V to 7.0V in 0.1V increments (accuracy: ±2.5%). Oscillator frequency is also selectable from three frequencies; 50, 100, and 180kHz (accuracy: ±15%).

Every built-in switching transistor type of XC6371 enables a step-up circuit to be configured using only three external components; a coil, a diode, and a capacitor. External transistor versions are available to accommodate high output current applications.

5-pin packages of XC6371, which are provided with either a CE (chip enable) function that reduces power consumption during shut-down mode, or a VDD p i n (separated power and voltage detect pins) are available. SOT-89 small package.
