产品概述 返回TOP
CXSD62128/A/B is a 3A synchronous buck converter with integrated 110mW power MOSFETs. The CXSD62128/A/B is designed with a current-mode control scheme; it can convert wide input voltage of 2.6V to 5.5V to the output voltage adjustable from 0.8V to 5.5V to provide excellent output voltage regulation. The CXSD62128/A/B is equipped with an 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. At PWM mode, the switching frequency is set by the external resistor. The CXSD62128/A/B is also equipped with Power-on-reset, soft-start, soft-stop, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package. This device, available TDFN3x3-10 and SOP-8P provides a very compact system solution external components and PCB area.
