一,产品概述(General Description)
The CXSD6134 is a high efficiency current-mode synchronous, 18V/2A buck converter.
Its input voltage ranges from 4.5V to 18V and it provides an adjustable regulated
output voltage from 0.923V to 15V 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 340KHz. And the
CXSD6134 will automatically switch between PFM and PWM mode based on the load
current, thus to enhance the converter efficiency at light load. CXSD6134 consists
of many protection block such as UVLO, input voltage over voltage protection
to stand much higher input voltage spike, thermal protection and output short
circuit protection.
The CXSD6134 is available in the SOP8 and ESOP8 (with exposed pad for heat
dissipation) package
