Linear Technology LT1313

the LT1313 forms a complete minimum component-count interface for palmtop, pen-based and notebook computers. The two VPP output voltages are independently selected by four logic compatible digital inputs which interface directly with industry standard PC Card Interface Controllers. The LT1313 is available in 16-pin SO packaging.

DESCRIPTION

The LT ® 1313 is a member of Linear Technology Corporation’s PCMCIA driver/regulator family. It provides 0V, 3.3V, 5V, 12V and Hi-Z regulated power to the VPP pins of two PCMCIA card slots from a single unregulated 13V to 20V supply. When used in conjunction with a PC Card Interface Controller, Automatic 3.3V to 5V switching is provided by two independent comparators which continuously monitor each PC card VCC supply voltage and automatically adjust the VPP output to match the associated VCC pin voltage when the VPP = VCC mode is selected. Two open-collector VPP VALID outputs are provided to indicate when the VPP outputs are in regulation at 12V. The LT1313 is available in 16-pin SO packaging. , LTC and LT are registered trademarks of Linear Technology Corporation.
