SC1144
Preliminary - August 24, 1999
An evaluation board is available which may be ordered directly from the factory. SC1144EVB is a DC/DC con-
verter utilizing the SC1144 four-phase controller in an asynchronous appliaction. The SC1144-SYNCH-EVB uti-
lizes SC1405 high speed MOSFET drivers to drive the TOP and Synchronous MOSFETs with enhanced features.
The evaluation boards are intended as guidelines for board design, layout and to assess key performance parame-
ters, such as transient response, thermal stress management and input and output ripple considerations. The
SC1144EVB includes a SLOT1 connector for Pentium II, a DIP switch for mode/voltage selection as well as quali-
fied selection of components for the SC1144 operation. The SC1144EVB user manual contains useful applications
information. Both Evaluation boards may be ordered from our website at www.semtech.com.
