一,产品概述(General Description)
The CXSD6144C is a high efficiency current-mode synchronous, 20V/2A buck
converter. Its input voltage ranges from 4.5V to 20V and it provides an
adjustable regulated output voltage from 0.923V to 17V while delivering up
to 2A of output current.
The internal synchronous switches increase efficiency and eliminate the need
for an external Schottky diode. The switching frequency is set to 350KHz.
CXSD6144C consists of many protection block such as UVLO, thermal
protection and output short circuit protection.
The CXSD6144C is available in the SOP8 and ESOP8 (with exposed pad
for heat dissipation) package
