Programmable DC/DC

Features
Applications
Revision 04/2001
Typical Application Circuit
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,
efficiency 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 increments
with no external components. Both the range and the
increment value may be changed by adding external
components.
The SC1150 provides an OVP output which can be used
to trigger a crowbar circuit for true over voltage protec-
tion.
