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 har-
monics on the backplane. The power dissipation is con-
trolled using a novel low voltage supply technique, allow-
ing high speed and integration, with the high drive cur-
rents to ensure low MOSFET switching loss.
The use of high speed switching circuits allows very nar-
row PWM outputs down to 15:1 voltage ratios. Single
pin compensation for each channel simplifies develop-
ment as well as reducing external pin count.
Capable of driving MOSFETs via external driver transis-
tors for phase currents beyond 20A.
