... Figures 1 and 2 show the approach that is very space and power efficient. The LTC1314/LTC1315 used in conjunc- tion with the LT1301 DC/DC converter, provide complete power management for a PCMCIA card slot. The LTC1314/ LTC1315 and LT1301 combination provides a highly effi cient, minimal parts count solution. These circuits are ...

... U With Higher Voltage Supplies Available Often systems have an available supply voltage greater than 12V. The LTC1314/LTC1315 can be used in conjunc- tion with an LT1121 linear regulator to supply the PC card socket with all necessary voltages. Figures 3 and 4 show these circuits. The LTC1314/LTC1315 enable the LT1121 linear regulator only when 12V is required at the VPP pins ...
