DC2002A - LTC3774EUHE Demo Board | Dual Buck Controller, 7V ≤ VIN ≤ 14, Vout1 = 1.2V @ 30A, Vout2 = 1.5V @ 30A
Demonstration circuit DC2002A is a dual output synchronous buck converter featuring the LTC3774EUHE. The demo board supplies two rails of 1.5V / 30A and 1.2V / 30A. The power stage for each rail consists of a 0.33μH 0.32mΩ DCR inductor with a 11mm × 11mm footprint and a 6mm × 6mm DrMOS driven by the PWM outputs of the LTC3774EUHE at a switching frequency of 400kHz.
