What is the switching voltage regulators switching voltage regulators use output level, repeat switch "open" and "off" status, and energy storage components (capacitor and sensor) together produce the output voltage. It is through the adjustment according to the output voltage feedback sample to adjust timing to fulfill. Switch In a fixed frequency stabilizer, adjust the switching voltage pulse width to adjust the switching timing? This is the so-called PWM control. In the gated oscillator or pulse mode, switch pulse voltage stabilizer width and frequency constant, but output switch "on" or "off" by the feedback control.
According to switch and energy storage components arrangement, produce the output voltage can be more or less than the input voltage, and can use a stabilizer produce more output voltage. In most cases, in the same input voltage and output voltage request, pulse (step-down) switching voltage regulators than linear regulators conversion power more efficiently.
