SC1164/5

DESCRIPTION
The SC1164/5 combines a synchronous voltage mode
controller with two low-dropout linear regulators
providing most of the circuitry necessary to implement
three DC/DC converters for powering advanced
microprocessors such as Pentium
II.
The SC1164/5 switching section features an integrated
5 bit D/A converter, pulse by pulse current limiting,
integrated power good signaling, and logic compatible
shutdown. The SC1164/5 switching section 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 con-
verter provides programmability of output voltage from
2.0V to 3.5V in 100mV increments and 1.30V to 2.05V
in 50mV increments with no external components.
The SC1164/5 linear sections are low dropout regula-
tors. The SC1164 supplies 1.5V for GTL bus and 2.5V
for non-GTL I/O.
For the SC1165 both LDO’s are adjustable.
