What Is a Linear Power Supply?
A linear LED power supply is an LED driver that convert unregulated DC voltage to a regulated DC voltage using a linear regulator. A linear regulator operates in the linear region of a pass element to regulate the output. The regulator typically comprises an internal reference voltage, an error amplifier (operational amplifier), a feedback voltage divider, a pass transistor and an output capacitor. The error amplifier monitors the reference/feedback difference and controls the power switch to keep the output at desired value. Linear regulators are step-down converters, which are similar to the switching type buck regulators. All linear regulators have a minimum dropout voltage, below which the regulators will cease to operate. A low dropout (LDO) linear circuit can regulate the output voltage even when there is a very small input-to-output differential voltage.
