产品概述 返回TOP
CXSD62158 is a 3A synchronous buck converter with integrated 110mW power MOSFETs. The CXSD62158 design with a current-mode control scheme, can convert wide input voltage of 4.5V to 24V to the output voltage adjustable from 0.8V to 20V to provide excellent output voltage regulation. The CXSD62158 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. The CXSD62158 is also equipped with Power-on-reset, softstart, and whole protections (over-temperature, and current-limit) into a single package. This device, available SOP-8P, provides a very compact system solution external components and PCB area
