The CXSD6224 is a wide input range, high-efficiency, high frequency DC-to-DC step-down switching regulator, capable of delivering up to 0.3A of output current. With a fixed switching frequencyof 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. It also maintains its switching frequency above 1MHz even at very low output current to keep it away from the PLC frequency, which is normally 500KHz. Together with the tiny package CXSD6224 is in, without external compensation components, it is an ideal solution for system designer with stringentboard space requirements. CXSD6224 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.
