DESCRIPTION
The SC1150 voltage mode controller contains most of
the circuitry necessary to implement a DC/DC converter
for powering the Intel Pentium
Pro microprocessor,
both in single and multiple processor configurations.
The SC1150 features an integrated D/A converter,
pulse by pulse current limiting, integrated power good
signaling, logic compatible shutdown and on-board over
voltage protection (OVP).
The SC1150 operates at a fixed frequency of 200kHz,
providing an optimum compromise between size, effi-
ciency and cost in the intended application areas.
The integrated D/A converter provides programmability
of output voltage from 2.0V to 3.5V in 100mV incre-
ments with no external components. Both the range
and the increment value may be changed by adding ex-
ternal components.
The SC1150 provides an OVP output which can be
used to trigger a crowbar circuit for true over voltage
protection.
