TOREX SEMICONDUCTOR XCL212

The XCL212 series achieves high efficiency while holding down output ripple across the full range of loads, from light to heavy, enabling the extension of battery operation time. The series have a high speed soft-start as fast as 1ms for quick turn-on. With the built-in UVLO function, the internal P-channel driver transistor is forced OFF when input voltage becomes 2.4V or lower.

GENERAL DESCRIPTION

The XCL211/XCL212series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (3.1mm×4.7mm, h=1.35mm). An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring. A wide operating voltage range of 2.7V to 6.0V enables support for applications that require an externally set output voltage can be selected. The XCL211/XCL212 series uses synchronous rectification at an operating frequency of 2.4MHz. PWM control (XCL211) or automatic PWM/PFM switching control (XCL212) can be selected. The XCL211 series has a fixed frequency, enabling the suppression of output ripple. It’s suitable for large-current application due to limit current is configured 4.0A. The integrated CL discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge switch located between the LX and GND pins. Due to CL discharge function, malfunction on LX is prevented when Stand-by mode.
