VCC and GND (38 V). Therefore, if the output is -5 V, the input voltage can range from 4.5 V
to 33 V.
As in the positive buck-boost, the maximum output current according to application
conditions is shown in Figure 37. The dashed line considers a more accurate estimation of
the duty cycles given by Equation 44, where power losses across diodes and the internal
power MOSFET are taken into account.
