Description

The SC2450 can be configured as a dual converter or a bi-phase converter for high current applications. The part is designed for point of use power supplies with 8.5-30V nominal backplane power sources. Multiple supplies can be synchronized together to prevent low frequency harmonics on the backplane. The power dissipation is controlled using a novel low voltage supply technique, allowing high speed and integration, with the high drive currents to ensure low MOSFET switching loss.
