Switching Regulator - Switcher
- Switching converters are often referred to as Switchers
- Conversion is based on the inductive storage and filtering methods
- Basic elements in the switchers are voltage source, Switch,inductor,capacitor,Diode
- Output voltage ripple depends on the inductor, capacitor and switching frequency
- Ideal efficiency is 100 % (lossless elements)
- Typical efficiency 90% +
Major differentiating points as compared to LDOs
- Wide Input voltage range (Vin)
- High Efficiency (> 90%)
- Compact in size when comparing with same output power
- Multiple phase and multiple outputs
Most widely used Switching Regulators
- Buck Converter
- Boost Converter
- Buck-Boost Converter
- Fly-back Converter
