• RE: Switched mode power supplies, LDOs and RF circuitry

    Hi Orlando,

    Switching power supply noise typically spans a frequency range of 300KHz and up. The LDO after the switcher is helpful in attenuating the lower frequency noise, and you can still get decent rejection up to about 1MHz. Take a look at the ADP7158…

  • RE: HMC7043 Power supply regulator design with HMC7043 EVM board.

    Hi,

    The currents that is used in calculation, includes all output drivers and all features when set to maximum current consuming condition and all PVT variations and also aging factor. For a typical configuration (some outputs are pulsed, analog delay…
