    input. The AAT115X peak current mode control loop senses the current flowing through the high-side P-channel MOSFET and compares it to the output of the voltage loop error amplifier. Sufficient sensed current slope is important for good noise immunity and a wide duty cycle dynamic range. Moreover
  • Using Low Resistance MOSFETs as Load Switches
    a resistor and therefore Ohms law applies; when turned off, the MOSFET appears as a diode and as such blocks current in one direction with a very high resistance (if reverse protection is required, an additional MOSFET or blocking diode is required). P-channel MOSFETs are normally used

    . The other terminal is called the drain terminal. Current flow between source and drain is related to the drain-source voltage by the resistance of the intervening material. In Figure 1b, p-type regions have been diffused into the n-type substrate of Figure 1a leaving an n-type channel between the source
