Linear vs. Switching 24VDC Power Supply for Mic Pre
If I have a 24 Volts DC
regulated stabilized output low ripple but switching power supply Can I use that for a microphone preamplifier module which requires 24VDC for operation? Or must it be linear or I will damage the unit? |

It will work. Or must it be linear or I will damage the unit? No and no. Depending how well the mic pre was designed it may or may not benefit more or less from a linear supply with even lower output noise. You omitted to mention the actuall ripple and noise voltage ( and measuring bandwidth ) from the switcher. Graham |

Graham It's an order of magnitude greater but still low? the switching is 0.1% vs 0.01% but that's still low anyway |

It is night-and-day different if you are talking about a battery charger vs. a supply for a delicate circuit like a mic preamp. Beware of power supply noise getting into the preamp circuit. Particularly a problem if it is supersonic where you may not immediately see the adverse effects. Do you have an oscilloscope available? |

Graham It's an order of magnitude greater but still low? the switching is 0.1% vs 0.01% but that's still low anyway The linear supplies I design have ~ 500uV of noise ( you can't really see any ripple ) in the audio band. How does that compare ? Graham |

Not even high end stuff actually, just well-engineered. You can do the same with any of the usual integrated regulators around using carful pcb layout in particular. Graham |
