LDK120M12R Working Principle

LDK120M12R is a high-power switching-mode and linear voltage regulator. It works by generating a regulated voltage output by smoothly varying the dutycycle of an internal oscillator and applying this signal to the input switching transistor, creating a pulse width modulated three-phase signal which is then filtered to hold a steady output voltage.

The linear voltage regulator contains two separate power sources: one to drive the switching transistor, which takes input current from the power source and provides the output cycle, and one to drive the output filter network, which takes input voltage from the power source and provides the output voltage. LDK120M12Rhaspower efficiency up to 94%, and output power around 160W. It can operate in a wide temperature range, due to its temperature compensation techniques.

LDK120M12R combines linear and switching-mode regulation techniques to achieve higher power efficiency, lower noise, and more reliable output voltage. This regulator is capable of working under wide temperature range, providing some of the most advanced power management capabilities available for modern processers. With its low output ripple, small footprint and high current output, LDK120M12R is a powerful ally in delivering a reliable, noise-free and safe power to your critical hardware.
