产品概述 返回TOPhsC嘉泰姆
The CXSD61047B is a synchronous step-down
DC/DC converter that provides wide 4.5V to
23V input voltage range and 3.5A continuous
load current capability.
The CXSD61047B fault protection includes cycle-bycycle
current limit, input UVLO, output over voltage
protection and thermal shutdown. Besides,
adjustable soft-start function prevents inrush current
at turn-on. This device uses current mode control
scheme which provides fast transient response.
Internal Compensation function reduces external
compensation components and simplifies the design
process. In shutdown mode, the supply current is
less than 1uA.
The CXSD61047B is available in an 8-pin SOIC package,
provides a very compact system solution and good
thermal conductance.
