com SC2449 POWER MANAGEMENT Description The SC2449 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.
5-28V 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 MOS.
ET switching loss.
The use of high speed switching circuits allows very narrow PWM outputs down to 15:1 voltage ratios.
Single pin compensation for each channel simplifies development as well as reducing external pin count.
Capable of driving MOS.
ETs via external driver transistors for phase currents beyond 20A.
