XCL201/XCL202 Series
ETR2802-004
Inductor Built-in Step-Down “micro DC/DC” Converters
☆ 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 0.42 ? P-channel driver transistor and 0.52 ? N-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 1.0 μ A 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 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.
