Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used. You can convert Watt-hours to Amp-hours by dividing by the battery’s nominal voltage (V) as follows: Ah = Wh / V
In the measurements, the battery is discharged at constant current, resistance or power, while the DC/DC converter generates fixed output voltages, unless it is out of regulation. Figure 3, Figure 4 and Figure 5 show the measured battery life achieved with the three devices used to generate voltages from 3 V to 4 V.
DigiKey's battery life calculator uses battery capacity (mAh) and device consumption (mA) to calculate estimated hours of battery life.
Consider a system consisting of a battery, a DC/DC converter and a load. The battery is 2500 mAh Li-ion type, with the discharge curve at 1 A shown in Figure 1. We can consider three types of loads: Constant power load – this can be a second DC/DC stage, or a device with an integrated DC/DC converter such as some RF power amplifiers.
A typical lithium-ion (Li-ion) battery voltage, for example, can change from 4.35 V down to 2.5 V during the discharge cycle. If we need to generate a fixed voltage within this range, the first solution that comes to mind is a non-inverting buck-boost converter. But is this always the best choice?
Choosing the right converter topology for a power supply usually starts by considering input and output voltages. If the input voltage is always higher than the required output voltage, a buck converter is the first choice, and if the input voltage is always lower than the required output voltage, a boost converter is the best bet.
