I have a circuit containing ACST6-7S AC switch. That power switch is used to put out 98Vrms, which drives another circuit (Circuit B). The problem is, the power switch needs to have 25mA-rms throughput in order to stay 'turned on'. The simplest solution is to just put a ~4k resistor in parallel with circuit B. However, this solution is not optimum because it will always be dissipating an extra ~3W of heat. What I'd really like is something which only draws extra current as needed. Circuit B will at times draw well over an amp. Another limitation is size - the solution, when manufactured, would have to fit in the palm of one's hand.
