Beschreibung

Demonstration Circuit DC3252A features the LTC3303A, 5 V, 4 A synchronous step-down silent switcher operating as a 2 MHz, 3.3 V to 1.2 V, 4 A buck regulator. The LTC3303A supports adjustable output voltages from 0.5 V to VIN. The LTC3303A 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 DC3252A operating mode can be selected as Burst Mode operation, skip (PS) or forced continuous (FC) mode. Setting JP1 to the SKIP position allows the LTC3303A to sync to a clock frequency from 1.6 MHz to 2.4 MHz. The LTC3303A operates in forced continuous mode when syncing to an external clock.
