Abstract

An apparatus and related aspects for providing reduced pressure to a tissue site are disclosed. The apparatus comprises an electrical load and a power supply arrangement connected to the electrical load. The power supply arrangement comprises a battery, a first voltage regulator connected to the battery, a second voltage regulator connected to the first voltage regulator and to the electrical load, and a capacitor connected to the second voltage regulator. The first voltage regulator is configured to receive an input voltage from the battery and to output a supply voltage to the second voltage regulator. Moreover, the first voltage regulator is further configured to, in response to the input voltage being above a first voltage level, output the supply voltage to the second voltage regulator based on the received input voltage. The first voltage regulator is further configured to, in response to the input voltage being below a second voltage level, output a zero-voltage to the second voltage regulator. The second voltage regulator is configured to, in response to receiving the supply voltage from the first voltage regulator at an input, output a first target voltage to the load based on the received supply voltage. The second voltage regulator is further configured to, in response to receiving the zero-voltage voltage from the first voltage regulator at the input, output a second target voltage to the load by discharging the capacitor.
