■FEATURES

■GENERAL DESCRIPTION

Operation Start Voltage Range: 0.9V~10V

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 Range : 2.0V~7.0V in 100mV increments

Highly Accurate

Oscillation Frequency : 50kHz, 100kHz, 180kHz (±15%)

: Setting voltage accuracy±2.5%

selectable (XC6371/72)

30kHz (XC6373)

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.

Maximum Output Currents (Tr. built-in)

100mA(TYP.) @ VIN=3.0V, VOUT=5.0V *

Highly Efficient (Tr. built-in)

: 85%(TYP.) @ VIN=3.0V, VOUT=5.0V *

Built-in switching transistor type.

Five-lead packaged units offer either chip enable or

independent VOUT pin option.

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.

Phase compensation and soft start-up circuits built-in.
