The FDMF3180 is ON’s latest generation Smart Power Stage (SPS) module for high-current, high frequency, synchronous DC-DC buck converter applications. It integrates fully optimized High Side and Low Side PowerTrench® 11 power MOSFETs with an advanced driver IC featuring current and temperature sensors.
With an integrated approach, the SPS switching power stage is optimized for driver and MOSFET dynamic performance, minimized system inductance, and power MOSFET RDS(ON).
The integration of Power MOSFETs with a driver IC enables advanced high accuracy module thermal and current monitoring. The FDMF3180 provides an output signal (IMON), which reports the real-time module current. IMON is a very accurate, 5μA/A signal representing the real-time Power MOSFET drain currents. The IMON signal can be used to replace output filter inductor DCR current sense or resistor sense methods.
The FDMF3180 also includes very accurate module thermal monitor (TMON). TMON is a voltage sourced PTAT signal that is calibrated to provide a 0.8 V output at 25°C with an 8 mV / °C slope.
