SI9122EDQ-T1-E3 General Description
Si9122E datasheet
SI9130 General 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 to 70) and extended commercial (−10 to 90) temperature ranges. See Ordering Information for corresponding part numbers.
