产品概述 返回TOP
CXSD62233 is a 3A synchronous buck converter with integrated power MOSFETs. The CXSD62233 design with a current‐mode control scheme, can convert wide input voltage of 4.5V to 30V to the output voltage adjustable from 0.92V to 28V to provide excellent output voltage regulation. The CXSD62233 is equipped with an automatic PFM/PWM mode operation. At light load, the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM mode. The CXSD62233 is also equipped with Power‐on‐reset, soft‐ start, and whole protections (over‐temperature, and current‐limit) into a single package. This device, available ESOP‐8, provides a very compact system solution external components and PCB area.
