9.2.3 Application Curve
See Table 3 for application curves.
9.2.4 Higher Output Voltage Designs
The SN6501 can drive push-pull converters that provide high output voltages of up to 30 V, or bipolar outputs of
up to ±15 V. Using commercially available center-tapped transformers, with their rather low turns ratios of 0.8 to
5, requires different rectifier topologies to achieve high output voltages. Figure 46 to Figure 49 show some of
these topologies together with their respective open-circuit output voltages.

9.2.5 Application Circuits
The following application circuits are shown for a 3.3 V input supply commonly taken from the local, regulated
micro-controller supply. For 5 V input voltages requiring different turn ratios refer to the transformer
manufacturers and their websites listed in Table 4.
