Build a Charge Pump with Ultra-Low Quiescent Current (Iq)
Abstract: Combining low-on-resistance analog switches with a reference and ultra-low quiescent current comparator produces a
discrete-component regulated charge pump that delivers 10mA, with only 7uA of quiescent current (Iq).
Portable, battery-powered devices often spend most of their life in standby mode, where the quiescent current of an internal boost
converter bleeds the battery continuously. The quiescent current during standby can be larger than the actual load current. Though
several inductor-ba……
