■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.

■PIN CONFIGURATION
*The dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and metal
masking so as to enhance mounting
strength and heat release. If the pad needs
to be connected to other pins, it should be
connected to the pin No.1.
