产品概述 返回TOP
The CXSD61006B is PWM DC/DC buck (step-down) regulators. With a wide input range from 4.75V-40V, they are suitable for a wide range of applications such as power conditioning from unregulated sources. They feature a low RDSON (0.9Ωtypical) internal switch for maximum efficiency 90%. Operating frequency is fixed at 550 KHz allowing the use of small external components while still being able to have low output voltage ripple. The system has PWM and PFM switching function to ensure high efficiency under low load. The built-in soft-start prevents inrush current at turn-on. the CXSD61006B is optimized for up to 800 mA load current. Both have a 0.8V nominal feedback voltage. Additional features include: thermal shutdown, VIN under-voltage lockout, and gate drive under-voltage lockout.
