The CXSD61056 is a wide input range, high-efficiency, high frequency DC-to-DC step-down switching regulator, capable of delivering up to 1.2A of output current. With a fixed switching frequency of 1.4MHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. Together with the tiny package CXSD61056 is in, without external compensation components, it is an ideal solution for system designer with stringent board space requirements. CXSD61056 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. 

CXSD61056 is available SOT23-6 Packages.
