Vishay's DrMOS compliant device with integrated MOSFETs and driver IC

Vishay's new SiC769 is fully compliant with the DrMOS specification for voltage regulators and operates with an input voltage range of 3 V to 16 V and delivers up to 35 A of continuous output current. Its integrated power MOSFETs are optimized for output voltages in the range of 0.8 V to 2.0 V, with a nominal input voltage of 12 V. The SiC769 can also deliver very high power at a 5-V output for ASIC applications.

The SiC769 with gate driver IC accepts a single PWM input from the VR controller and converts it into the high- and low-side MOSFET gate drive signals. The PWM input is compatible with all controllers and designed to support controllers with tri-state PWM output function.

The driver IC incorporates circuitry to automatically detect light load conditions and enables the skip mode operation (SMOD) in systems that are designed for high light load efficiency. An adaptive dead time control helps to further improve efficiency. Protection features include UVLO, shoot-through protection, and a thermal warning feature that alerts the system in case of an excessive junction temperature.

Integration of the driver IC and power MOSFETs in the SiC769 reduces power losses and lessens the effect of parasitic impedances associated with high-frequency discrete power stage implementations.
