XCL201/XCL202 Series
Inductor Built-in Step-Down “micro DC/DC” Converters
ETR2802-003
GreenOperation Compatible
GENERAL DESCRIPTION
The XCL201/XCL201 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 400mA is configured using
only two capacitors connected externally.
Operating voltage range is from 2.0V to 6.0V. Output voltage is internally set in a range from 0.8V to 4.0V in increments of
0.05V. The device is operated by 1.2MHz, and includes 0.42P-channel driver transistor and 0.52N-channel switching
transistor. As for operation mode, the XCL201 series is PWM control, the XCL202 series is automatic PWM/PFM switching
control, 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. The
series provide short-time turn-on by the soft start function internally set in 0.25ms (TYP). The series integrate CL auto
discharge function which enables the electric charge stored at the output capacitor CL to be discharged via the internal
auto-discharge switch located between the LX and VSS pins. When the devices enter stand-by mode, output voltage quickly
returns to the VSS level as a result of this function.

difference between the input and the output is small, some cycles may be skipped completely before current maximizes.
If current is further pulled from this state, output voltage will decrease because of P-ch driver ON resistance.
