PRODUCTION DATA
The IPROPI output accuracy is ±3.5% for 40% to 100% of rated current. If more accurate current sensing is desired, external sense resistors can also be used between the PGND pins and the system ground to sense the load currents, as shown below.
The voltage drop across the external sense resistor should not exceed 300 mV.
Place the sense resistors as close as possible to the corresponding IC pins. Use a symmetrical sense resistor layout to ensure good matching. Low-inductance sense resistors should be used to prevent voltage spikes and ringing. For optimal performance, the sense resistor should be a surface-mount resistor rated for high enough power.
