Abstract:
1. A system comprising: a variable load having a first mode of operation requiring a first current level and a burst current mode of operation requiring a second current level, wherein the second current level is greater than the first current level; a control processor for providing control signals; a voltage source connected to the variable load for providing a source current, the source current providing the load the first current level in the first mode of operation; a burst mode circuit for providing the second current level to the variable load in the burst current mode of operation, responsive to the control signals from the control processor and the voltage source, comprising: wherein the circuitry connects the capacitor to ground in the first mode of operation responsive to the control signals causing the capacitor to charge to a voltage level provided by the voltage source and the circuitry in the second mode of operation causes a discharge of the voltage level on the capacitor and a generation of a boost current that is combined with the source current from the voltage source to generate the second current level to the variable load responsive to the control signals, the control signals further to disconnect the capacitor from ground responsive to removal of the variable load.
