Built-in support for light-load Burst Mode , Ideal Diode Emulation , and synchronous rectifier soft on/off.

In high-power systems, PFC is required to maintain input current in phase with the input voltage. The UCD3138 manages this via a dedicated DPP configured for Average Current Mode Control. The controller monitors the input voltage waveform and shapes the inductor current accordingly. The hardware multiplier assists in the rapid calculations needed for the multiplication of the voltage feed-forward term, ensuring high Power Factor (PF > 0.99) and low Total Harmonic Distortion (THD). ucd3138r
