Analog Devices LTC3310S | Demoboard DC2629A

Description

Demonstration Circuit DC2629A features the LTC®3310S10A, Low Voltage, Synchronous Step-Down Silent Switcher® 2 operating as a 2MHz 3.3V to 1.2V 10A buck regulator. The LTC3310S supports output voltages from 0.5V to VIN with operating frequencies from 500kHz up to 5MHz. The LTC3310S 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
