Hardware Protection – OverVoltage and OverCurrent

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) […]

The Advantages and Drawbacks of DC to DC Voltage Converters with Integrated Inductors

The Advantages (and Drawbacks) of DC-to-DC Voltage Converters with Integrated Inductors

Such is the popularity of DC-to-DC voltage converters (“switching regulators”)––due to their high efficiency across wide input- and output-voltage ranges––that chip makers have focused a lot of research dollars on squeezing the essential components of the devices into modules. These modules typically include pulse-width-modulation (PWM) controllers and switching elements in a single, compact package, easing

High-voltage buck regulators stay cool in tiny packages

A family of pin-compatible synchronous step-down switching regulators with integrated power switches, the MIC28511/12/13 from Micrel, supplies up to 4 A of output current (MIC28513) and accepts a wide input supply range of 4.6 V to 70 V (MIC28512). The devices have an operating junction temperature range of -40°C to +125°C and come in very
