IRS2158D(S)
PCB Layout Considerations
In order to successfully utilize the IRS2158D in a ballast design, it is necessary to follow the following PCB
layout guidelines. This can avoid possible interference and ground loop issues that can occur in the ballast
circuit. These connection techniques also prevent high current ground loops from interfering with sensitive
timing component operation and allow the entire control circuit to reject common-mode noise due to output
switching.
Figure 10 and Figure 11 show the control section of typical ballast designed around the IRS2158D, where
the IC is located in the center. In this design all SMD devices are mounted under the PCB with discrete
devices on top.

1) The signal ground (pin 12) should only be connected to the power ground at one single point to prevent
ground loops from forming.
2) The point described in (1) should be where the grounds of the current sense resistors for both the half
bridge MOSFETs and the lamp current feedback both meet.
3) The VCC decoupling capacitor should be placed as close to the IRS2158D VCC (pin 13) and COM (pin
12) as possible with the shortest possible traces.
4) The devices; CPH, RMIN, CVCO, CT and CCS should all be located as close to the IRS2158D as
possible with traces to the relevant pins being as short as possible.
5) The ground connections from the devices listed in (4) should be connected back to the COM pin of the
IRS2158D through the shortest possible traces. These should be connected back to the COM pin of the
IC without joining the power ground trace at any point. In the example shown above the power ground
trace runs along the lower side of the board on the bottom Copper layer
6) The charge pump diode connection to ground should be made to the power ground not the signal ground.
7) The power factor correction section (if used) should be kept apart from the ballast control as shown in the
example above. the power factor correction section is at the left side of the PCB.
