XCL205/XCL206/XCL207Series

Inductor Built-in Step-Down “micro DC/DC” Converters

■GENERAL DESCRIPTION

ETR2801-005c

☆GreenOperation Compatible

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. 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 0.52ΩN-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/XCL206B/XCL207B series provide short-time turn-on by the soft start function internally set in 0.25 ms

(TYP). XCL205B(C) /XCL206 B(C) / XCL207B(C) integrate C_Lauto discharge function which enables the electric charge

stored at the output capacitor C_Lto be discharged via the internal auto-discharge switch located between the L_Xand V_SSpins.

When the devices enter stand-by mode, output voltage quickly returns to the V_SSlevel as a result of this function.
