Datasheet Details

uP1961S Dual-Phase MOSFET Drivers for DCR current sensing with Phase Extension.

The uP1961S is a high performance gate driver IC with Phase Extension Module (PEM). The PEM interleaves the single PWM input and drives dual-phase synchronous buck power stages. The PEM also extracts and passes the dual-phase current signals to the controller. When operating with uPI’s VR controllers with DCR current balance scheme, the uP1961S can double the phase number with perfect phase interleaving and channel current balancing. Each driver is capable of driving a 5000pF load with 30ns tra.
