FDMF3180 — Smart Power Stage (SPS) Module with Integrated Current and Temperature Monitors
November 2016
FDMF3180 – Smart Power Stage (SPS) Module with
Integrated Current and Temperature Monitors
Features
ON’s PowerTrench® 11 MOSFET Technology:
~0.5% Higher Peak Efficiency vs. Prior Generation
30 V/25 V Breakdown Voltage MOSFETs to Ensure
Long Term Reliability
Up to 70 A of Peak Current Handling Capability
High-Performance, 5 mm x 6 mm, Universal
Footprint PQFN Package
Integrated Current Monitor (IMON) Compliant with
Intel’s VR13 Accuracy Requirements
Integrated Temperature Monitor (TMON)
Catastrophic Fault Detection Features
Description
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 R
DS(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, 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 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.
