SC2450

BI-Phase/Dual Controller

POWER MANAGEMENT

ꢀeatures

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 10-30V

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 MOSꢀET switching loss.

u Selectable dual output or bi-phase operation

u Direct drive for N-channel MOSꢀETs

u Undervoltage lockout

u Synchronization to external clock

u Multi-converter synchronization

u Soft start

u ꢀast transient response

u Max duty cycle 45%

u Output over voltage protection

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.

Applications

Power supplies for advanced telecoms/datacoms

SO IP, Ethernet and PABX power supplies

Capable of driving MOSꢀETs via external driver transis-

tors for phase currents beyond 20A.
