Hardware Protection – OverVoltage and OverCurrent

Three major power supply (Figure 1) architectures are defined for any engineer: 1.Linear Regulators. 2.Pulse width modulated switching (PWM). 3.High resonant technology switching. Some important parameters can described in the followig texts: Inputs: Vin(low), Vin(high) – minimum and maximum allowed input voltages, hence input voltage range. Iin(max) – maximum average input current. Outputs: Vout(min), Vout(max) …
