DESCRIPTION
The Si9130 Pin-programmable Dual Controller for Portable
PCs is a pin-programmable version of the Si786 dual-output
power supply controller for notebook computers. The Buck
controllers provide 5 V and a pin-programmable output delivering
3.3 V, 3.45 V, or 3.6 V.
The circuit is a system level integration of two step-down
controllers and micropower 5-V and 3.3-V linear regulators.
The controllers perform high efficiency conversion of the
battery pack energy (typically 12 V) or the output of an ac to dc
wall converter (typically 18-V to 24-V dc) to 5-V and 3.3-V
system supply voltages. The micropower linear regulator can
be used to keep power management and back-up circuitry
alive during the shutdown of the step-down converters.
A complete power conversion and management system can
be implemented with the Si9130
Pin-programmable Dual
Controller for Portable PCs, an inexpensive linear regulator,
the Si9140 SMP Controller for High Performance Processor
Power Supplies, five Si4410 n-channel TrenchFET Power
MOSFETs, one Si4435 p-channel TrenchFET Power
MOSFET, and two Si9712 PC Card (PCMCIA) Interface
Switches.
The Si9130 is available in both standard and lead (Pb)-free
28-pin SSOP packages and specified to operate over the
commercial (0 C to 70 C) and extended commercial (
10 C
to 90 C) temperature ranges. See Ordering Information for
corresponding part numbers.
