Working Principle

The REC3-4812SRW/H4/C/SMD-R is a linear voltage regulator IC with an internal high voltage oscillator, designed to convert a low input voltage to a higher output voltage. The device operates by switching its output voltage rapidly between two levels determined by the two-level voltage converter\'s controller. When the output voltage reaches the upper threshold, the converter switches off, and when the output voltage reaches its lower threshold, the converter switches on. When the device is in operation, the input voltage is used to control the converter\'s output voltage and output current. This device employs an internal voltage loop control system, which ensures a stable output voltage with 120dB ripple rejection and 2% accuracy.
