Voltage control circuitry for charging output capacitor

摘要: Battery driven voltage control circuitry charges an output capacitor, which periodically supplies a current pulse. The converts battery VBAT to charging VUPC based upon programmed parameters and the VCOMPL at capacitor. includes converter for multiplying produce VUPC. is sampled determine its “droop” end of If droop lower than threshold, then increases voltage. above reduces This feedback maintains within acceptable operating range efficacious pulse stimulation without causing unproductive energy loss. In order avoid premature depletion energy, compared with optimum clock rate be used convert
