■General Description

■Features

The XC6373 is a group of PWM controlled step-up DC/DC converter ICs.

The XC6373 series employs CMOS process and laser trimming

technologies so as to attain low power and high accuracy.

The implemention of a new phase compensation circuit and a slow start

function ensure excellent transient response and improved performance.

The series is particularly suited for use with pager applications because

of their low power consumption and low noise characteristics.

Output voltage can be selected from 2.0V to 7.0V in 0.1V increments

(accuracy; 2.ꢀ5%. Oscillator freꢁuency is set at 30ꢂkH ( 205% so as to

attain the lowest consumption current possible.

Operating (start-up) voltage range

: 0.9V~10V

Output voltage range : 2.0V~7.0V in 0.1V increments

Highly accurate

: Set-up voltage 2.ꢀ5

Oscillator frequency : 30ꢂkz ( 205%

Maximum output current (Tr. Built-In)

: ꢀ0mA (TYP.% @ VIN=3.0V,

VOUT=ꢀ.0V ....Note (1%

Highly efficient (Tr. Built-In)

: 825 (TYP.% @ VIN=3.0V,

VOUT=ꢀ.0V ....Note (1%

A step-up converter circuit can be configured using the XC6373 IC with a

coil, a diode, and a capacitor.

Either chip enable or independent VOUT pin option is

selectable for 5-pin package units.

ꢀ-pin pacꢂages, which are provided with either a CE (Chip enable%

function that reduces power consumption during shut-down mode, or a

V^DDpin (separated power and voltage detect pins% are available.

SOT-89 small pacꢂage.

Phase compensation and slow start-up circuits included.

Small Package

: SOT-89 mini-power mold (3-pin, ꢀ-pin%

Note (1%: Performance depends on external components and

PCB layout.
