Shutdown quiescent current
Did you know?
Webquiescent current is very low, typically 42μA, which is well suitable for battery-powered applications to increase standby time. Despite such low quiescent current, the transient … WebDuring PSM, the peak inductor current (IL_PEAK) is controlled by the minimum on-time of high-side MOSFET to ensure the low output voltage ripple. During non-switching period, most of the internal circuit is shut down, and the supply current drops to quiescent current (100 μA, typically) to reduce the quiescent power consumption.
WebThe MAX893L’s maximum programmed current limit is 1.2A. The typical short-circuit current is 1.5 times the programmed current; therefore, a 1.2A programmed limit will … WebBy the way that would be 50 mA per each pair of output transistors, so you can imagine the idle current of a 1,500 watt amplifier with ten output pairs. The output emitter resistors …
WebQ measures operating current, not shutdown current, so the device must be on. Lastly, I Q is meaningful only in power-save mode, so if this mode is an option for ... Q Quiescent … WebJul 16, 2024 · Off-the-shelf regulated charge pumps with output-current capabilities ≥10mA have typical minimum quiescent currents of 50 to 100µA. If that level of quiescent current is not acceptable, you can reduce the overall average by adding circuitry that monitors the regulated voltage remotely and toggles the charge pump in and out of shutdown.
WebHaving high current and/or a wide differential between input and output voltage could lead to large power dissipation. Additionally, efficiency will suffer as the differential widens. …
