PWM/PFM Switching Control (XC9207 / XC9208)

GENERAL DESCRIPTION
The XC9206/9207/9208 series is a group of DC/DC converters with a
built-in 0.4Ω P-channel driver transistor, offered in a SOT-25
package. The ICs are designed to provide high efficiencies and a
stable power supply with an output current of 500mA using only a
coil, a diode and two ceramic capacitors connected externally.
Minimum operating voltage of the XC9206/9207 is 1.8V and 2.0V for
XC9208. Output voltage is internally programmable in a range from
0.9V to 4.0V in increments of 100mV (accuracy:
±2.0%).
Oscillation frequency is selectable from 300kHz, 600kHz and 1.2MHz
so that the frequency best suited to your particular application can be
selected.
Each series features different operation modes:
PWM control (XC9206 series), automatic PWM/PFM switching
control (XC9207 series) and manual PWM/PFM switching control
(XC9208 series). The series gives fast transient response, low ripple
and high efficiency over the full range of load (from light load to high
output current conditions). The soft start and current control
functions are internally optimized. During stand-by, all circuits are
shutdown to reduce current consumption to as low as 1.0µA or less.
With the built-in U.V.L.O. (Under Voltage Lock Out) function, the
internal P-channel driver transistor is forced OFF when input voltage
becomes 1.4V or lower.
