产品概述 返回TOP
The CXSD62302 is a synchronous step -down DC/DC converter
that provides wide 4.5V to 21V input voltage range and 2A
continuous load current capability.The CXSD62302 fault protection
includes cycle -by-cycle current limit, UVLO, output overvoltage
protection and thermal shutdown. The adjustable soft-start function prevents inrush current at turn-on. This device uses current mode
control scheme which provides fast transient response. nternal
compensation function reduces external compensation components
and simplifies the design process. In shutdown mode, the supply
current is less than 1μA.The CXSD62302 is available in SOT-23-6 package
and provides good thermal conductance.
