XCL205/XCL206/XCL207 Series
ETR2801-012
Inductor Built-in Step-Down “micro DC/DC” Converters
☆ GreenOperation Compatible
■ 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:1.8V ～ 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 3.0MHz, and includes 0.42 Ω P-channel driver transistor and 0.52 Ω
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 1.0 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. XCL205B(G)/XCL206B(G)/XCL207B(G) series provide short-time turn-on by the soft start function
internally set in 0.25 ms (TYP). XCL205B(C,G) /XCL206 B(C,G) / XCL207B(C,G) 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.
