Description

The FDMF3170 is ON

’s next generation of Smart Power

Stage (SPS) solutions with fully optimized, ultra-

compact, integrated MOSFETs plus driver for high-

current, high frequency, and synchronous buck DC-DC

converters.

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 also

enables advanced high accuracy module thermal and

current monitoring. The FDMF3170 provides an output

signal (IMON), which reports the real-time module

current. IMON is a very accurate, 5 µA/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 FDMF3170 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.
