■GENERAL
DESCRIPTION
The XCL205/XCL206/XCL207 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a
control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is
configured using only two capacitors connected externally.
Operating voltage range is from 2.0V to 6.0V
(XCL20xG:1.8V½6.0V)
. Output voltage is internally set in a range from 0.8V to
4.0V in increments of 0.05V. The device is operated by 3.0MHz, and includes 0.42ΩP-channel driver transistor and 0.52Ω
N-channel switching transistor. As for operation mode, the XCL205 series is PWM control, the XCL206 series is automatic
PWM/PFM switching control and the XCL207 series can be manually switched between the PWM control mode and the
automatic PWM/PFM switching control mode, allowing fast response, low ripple and high efficiency over the full range of loads
(from light load to heavy load). During stand-by, the device is shutdown to reduce current consumption to as low as 1.0μA or
less. With the built-in UVLO (Under Voltage Lock Out) function, the internal driver transistor is forced OFF when input voltage
becomes 1.4V or lower. XCL205B(G,F)/XCL206B(G,F)/XCL207B(G,F) series provide short-time turn-on by the soft start
function internally set in 0.25 ms (TYP). XCL205B(C,G,F) /XCL206 B(C,G,F) / XCL207B(C,G,F) integrate C
L
auto discharge
function which enables the electric charge stored at the output capacitor C
L
to be discharged via the internal auto-discharge
switch located between the L
X
and V
SS
pins. When the devices enter stand-by mode, output voltage quickly returns to the V
SS
level as a result of this function.

In low temperature environment, the battery level of the device is displayed as 90%, but when it is brought to normal temperature, the battery level drops rapidly until it shuts down. What is the principle behind this?
Hello everyone, I did a low temperature environment test on the device (the device specification book states that the nominal low temperature working temperature can reach -20 degrees). The actual tes...
