In lightly loaded battery applications that require regulated power supplies, the quiescent current drawn by the DC/DC converter can represent a substantial portion of the average battery current drain. In such applications, minimizing the quiescent current of the DC/DC converter becomes a primary objective because this results in longer battery life and/or an increased power budget for the rest of the circuitry. The following two circuits provide regulated step-up and step-down DC/DC conversion ...
