Description

General part information

LTC3308A Series

Demonstration circuit 2991A features the LTC®3308A 5V, 4A synchronous step-down Silent Switcher® operating as a 2MHz, 3.3V to 1.2V 4A buck regulator. The LTC3308A supports adjustable output voltages from 0.5V to VIN with operating frequencies from 1MHz up to 3MHz. The LTC3308A is a compact, ultralow emission, high efficiency and high speed synchronous monolithic stepdown switching regulator. A minimum on-time switching of 22ns enables high VIN to low VOUT conversion ratios at high frequencies.
