Ive simulated in the pspice (with the original receiver, which is hardly indutive in the switch freqeuncy) and it had no problem to use it with no output filter. It works very well. Its efficience rounds about 88% suplied with 1Vdc and driving the receiver with 500uA. Is there another problem in not use a filter in a sigma delta modulator ? Thanks
