In this reference design, a lithium polymer battery is added to the output of the boost converter to absorb the pulse load current and extend the alkaline battery life time. The designed circuit also benefits uninterrupted power supply when the alkaline battery is out of charge. All Design files. TPS61220.
A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input. Figure 1, Figure 2, and Figure 3 illustrate ...
