Beschreibung

Demonstration Circuit DC3203A features the LTC3304A, 5 V, 6 A synchronous step-down silent switcher operating as a 2 MHz, 3.3 V to 1.2 V, 6 A buck regulator. The LTC3304A supports adjustable output voltages from 0.5 V to VIN. The LTC3304A is a compact,high efficiency, and high-speed synchronous monolithic step-down switching regulator. A minimum on-time of 27 ns enables high VIN to low VOUT conversion.The DC3203A operating mode can be selected as Burst Mode operation, skip (PS), or forced continuous (FC) mode. Setting JP1 to the SKIP position allows the LTC3304A to sync to a clock frequency from 1.6 MHz to 2.4 MHz. The LTC3304A operates in forced continuous mode when syncing to an external clock.The DC3203A also has an EMI filter to reduce conducted EMI. This EMI filter can be included by applying the input voltage at the VIN EMI terminal. The EMI performance of the board is shown in the EMI Test Results section. The red lines in the EMI performance graphs show the CISPR25 Class 5 peak limits for the conducted and radiated emission tests.
