LED knowledge
Linear power supply voltage feedback circuit is working in linear state of the switch power supply is used for voltage regulation of the pipe work in saturated and by area is the state of the switch.
Linear power supply is typically the output voltage sampling and then compared with the reference voltage into voltage amplifier, the voltage amplifier output as input of the voltage adjustment pipe, adjust the tube to control the changes over the input voltage, so as to adjust the output voltage, but the switching power supply is by changing the time to adjust the tube and off the duty ratios change output voltage!
Look from its main features: linear power supply technology is mature, lower production costs, can achieve a high degree of stability, the ripple is small, and there is no switch power supply with the interference and noise, but the relative volume, switch power supply is huge, and the input voltage range is high; The switching power supply in contrast.
