It is hard to imagine a notebook computer without a PC Card slot or two, and it is even harder to imagine just how much the 132 Mbps Cardbus interface adds to this application. TI has developed a Cardbus system solution ideally suited for even the most demanding multimedia applications. The PCI1250A or PCI1220 combine with the TPS2206 to provide the highest performance PC Card interface on the market.

Holding the majority of the Cardbus market, the PCI1220 and PCI1250A provide data throughput at the theoretical maximum for a 32-bit, 33-MHz PCI bus. They provide a high- speed interface between the PCI bus and a VGA controller for Zoomed video applications, and two 16-bit or Cardbus slots. These devices also feature the industry's most highly integrated controller with programmable IRQ pin assignments, four additional GP I/O pins, and enhanced burst mode data transfers with advanced power management capabilities.

Due to their commanding performance, the TPS2205 and TPS2206 have managed to gain a big portion of the entire Notebook PC Market. These power distribution switches combine low rDS(on) with: over-current and thermal protection, 3.3-V, 5-V and 12-V switching, and a 3.3-V low-voltage mode to provide the best price for performance package in the industry.

The TPS2206 uses TI’s P2C 3-line serial interface, and is the only switch on the market with a glueless interface to the PCI12xx and PCI11xx Cardbus controllers. The TPS2205 uses an older 8-line parallel interface for standard 16-bit devices.
