8 / 12 page LTC1046 8 S APPLICATI TYPICAL Battery Splitter A common need in many systems is to obtain positive and negative supplies from a single battery or single power supply system. Where current requirements are small, the circuit shown in Figure 10 is a simple solution. It provides symmetrical positive or negative output voltages, both Figure 10.

The output voltages are both referenced to Pin 3 (output common). If the input voltage between Pin 8 and Pin 5 is less than 6V, Pin 6 should also be connected to Pin 3, as shown by the dashed line. Paralleling for Lower Output Resistance Additional flexibility of the LTC1046 is shown in Figures 11 and 12. Figure 11 shows two LTC1046s connected in parallel to provide a lower effective output resistance. If, however, the output resistance is dominated by 1/fC1, increasing the capacitor size (C1) or increasing the fre- quency will be of more benefit than the paralleling circuit shown. Figure 12 makes use of “stacking” two LTC1046s to provide even higher voltages. In Figure 12, a negative voltage doubler or tripler can be achieved depending upon how Pin 8 of the second LTC1046 is connected, as shown schematically by the switch. 1 2 3 4 8 7 6 5 V + OSC LV VOUT BOOST CAP + GND CAP – LTC1046 C1 10 µF C1 10 µF + 1 2 3 4 8 7 6 5 V + OSC LV VOUT BOOST CAP + GND CAP – LTC1046 1/4 CD4077 + C2 20 µF 1046 F11 VOUT = –(V +) OPTIONAL SYNCHRONIZATION CIRCUIT TO MINIMIZE RIPPLE V+ Figure 11.
