Beschreibung

Demonstration Circuit 3018A features the LTC®3311S 12.5A, low voltage, synchronous step-down Silent Switcher® 2 operating as a 2MHz 3.3V to 1.2V 12.5A buck regulator. The LTC3311S supports output voltages from 0.5V to VIN with operating frequencies from 500kHz up to 5MHz. The LTC3311S is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. The integrated bypass capacitors optimize all the fast current loops and make it easier to minimize EMI/EMC emissions by reducing layout sensitivity. Fast minimum on-time of 35ns enables high VIN to low VOUT conversion at high frequency.
