Low output voltage ripple and small external CXSD62493 CXSD62493A CXSD62493B is a high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to2Aoutput current

   产品概述 返回TOPtZP嘉泰姆

The CXSD62493 CXSD62493A CXSD62493B is a high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to2Aoutput current. The CXSD62493 CXSD62493A CXSD62493B operates over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.tZP嘉泰姆

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

CXSD62493 CXSD62493A CXSD62493B integrates short circuit and over-voltage latch off protection.tZP嘉泰姆
