Working Principle of REG71050DDCRG4

The REG71050DDCRG4 is a synchronous buck regulator which converts a DC input voltage to a lower, regulated output voltage. It utilizes an internal power switch, typically a MOSFET, which is switched at a predetermined frequency. The switching action generates a pulse-width-modulated (PWM) waveform, which is then converted to a lower, regulated voltage via a low-pass filter. The internal synchronous rectification circuitry of the REG71050DDCRG4 also enables improved conversion efficiency, as the converter switch is turned on and off more quickly.

The REG71050DDCRG4 features precision power management features such as dynamic phase-lock loop (DPLL) to ensure stability and jitter-free operation over a wide range of frequencies. The integrated over-temperature protection and over-current protection further ensure safety and reliability. The integrated current feedback circuitry and PWM control ensure superior load transient response and good line and load regulation. With its fast start-up time and low dropout voltage, the REG71050DDCRG4 is highly suitable for powering low-voltage, high-current applications.
