Figure 41. DBV Package PCB Layout Example
Figure 42. DGN Package PCB Layout Example
The following procedure requires iteration because power loss is due to the internal MOSFET I2
× RDS(ON), and
RDS(ON) is a function of the junction temperature. As an initial estimate, use the RDS(ON) at 125°C from the
TYPICAL CHARACTERISTICS, and the preferred package thermal resistance for the preferred board
construction from the THERMAL INFORMATION table.
TJ = TA + ((IOUT2 x RDS(ON)) x θJA)
(1)
Where:
IOUT = rated OUT pin current (A)
RDS(ON) = Power switch on-resistance at an assumed TJ (Ω)
TA = Maximum ambient temperature (°C)
TJ = Maximum junction temperature (°C)
θJA = Thermal resistance (°C/W)
If the calculated TJ is substantially different from the original assumption, estimate a new value of RDS(ON) using
the typical characteristic plot and recalculate.
If the resulting TJ is not less than 125°C, try a PCB construction and/or package with lower θJA .
