The CXSD62490 CXSD62490A CXSD62490B CXSD62490E is a high-efficiency, high frequency synchronous step-down DC/DC regulator capable of delivering up to 3A output current. The CXSD62490 CXSD62490A CXSD62490B CXSD62490E operates over a wide input voltage range from 2.7V to 5.5V and integrates main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.qPm嘉泰姆

Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency.qPm嘉泰姆

     CXSD62490 CXSD62490A CXSD62490B CXSD62490E integrates reliable short circuit and over-voltage protection.qPm嘉泰姆
