These devices monitor the input voltage and control an external nMOSFET switch to isolate the load at the output during an input overvoltage condition.
The number of cycles(maximum 32) depends on the initial wiper position and the input voltage.
クロックサイクルの数(最大32)は、最初のワイパ位置と入力電圧に依存します。
Also, when the voltage of the power-receiving side coil is constant, the input voltage on the power supply side changes, and the supply power itself reduces.
また、受電側コイルの電圧が一定の場合、給電側の入力電圧が変化し、給電電力そのものが低下します。
Linear Voltage Regulators Linear voltage regulators use an active pass element(bipolar or MOSFET) to drop the input voltage down to the regulated output voltage..
What is Brownout Function? The brownout function is a protective function to stop switching operation if the input voltage VIN goes lower than the voltage required for normal operation.
The waveform diagram on the left indicates the behavior when the input voltage Vin falls in a range so as not to drop below the output voltage Vout shown as Vo in the circuit diagram.
The MAX16807/MAX16808 can be used in buck, boost, or SEPIC mode depending on the input voltage range and the number of LEDs in series per output string.
Let us now change the input voltage of 5V used as an example in Figure 24 to 3.6V, where 5V can be a system voltage, and 3.6V, the voltage of a rechargeable lithium ion battery.
The“low end” of 230Vac -10% is 207Vac; this is inside the normal range of 220Vac -10%(which is 198Vac), so there's no problem on the low end of the input voltage range.
