39 / 44 page  ADP1874/ADP1875 Rev. 0 | Page 39 of 44 DIFFERENTIAL SENSING Because the ADP1874/ADP1875 operate in valley current- mode control, a differential voltage reading is taken across the drain and source of the lower-side MOSFET. The drain of the lower-side MOSFET should be connected as close as possible to the SW pin (Pin 15) of the IC. Likewise, the source should be connected as close as possible to the PGND pin (Pin 13) of the IC. When possible, both of these track lines should be narrow and away from any other active device or voltage/current path. LAYER 1: SENSE LINE FOR SW (DRAIN OF LOWER MOSFET) LAYER 1: SENSE LINE FOR PGND (SOURCE OF LOWER MOSFET) PGND SW Figure 96. Drain/Source Tracking Tapping of the Lower-Side MOSFET for CS Amp Differential Sensing (Yellow Sense Line on Layer 2). Differential sensing should also be employed between the outermost output capacitor and the feedback resistor divider (see Figure 93 and Figure 94). Connect the positive terminal of the output capacitor to the top resistor (RT). Connect the negative terminal of the output capacitor to the negative terminal of the bottom resistor, which connects to the analog ground plane as well. Both of these track lines, as previously mentioned, should be narrow and away from any other active device or voltage/ current path. |
