5V至14V输入电源2A连续输出电流固定500kHz开关频率CXSD62376效率高达95%内部软启动脉宽调制/功率因数调制

The CXSD62376 is a high efficiency, 2A buck converter with two low RDS(ON) switches. It operates from 5V to 14V input voltage range, and provides up to 2A continuous output current with the output voltage adjustable down to 0.8V. Whenever the load is light, the CXSD62376 automatically change the PWM operation mode to PFM operation to minimize the power consumption. Hence it is suitable for battery-powered devices. The CXSD62376 is available in a SOP-8 package.
