50 A VRPower® Solution (DrMOS)
The SiC780/A is a 50 A VRPower® solution that integrates a high-side and low-side
MOSFET and a MOSFET driver optimized for synchronous buck applications. The device
complies with the Intel 4.0 DrMOS standard. It delivers up to 50 A continuous output
current and can operate from an input voltage range of 4.5 V to 16 V. The SiC780/A is
optimized for high switching frequencies of up to 1 MHz and is compatible with tri-state
PWM logic (3.3 V for the SiC780A, 5 V for SiC780). The device is optimized for output
voltages in the range of 0.8 V to 2 V.
