11 / 12 page CONSONANCE www.consonance-elec.com 11 Rev.1.1 diode and the pass transistor should also be kept as short as possible. (2) The compensation capacitor connected at the COM1, COM2 and COM3 pins should return to the analog ground pin of the IC. This will prevent ground noise from disrupting the loop stability. (3) Since MPPT pin’s voltage is a function of ambient temperature, while designing the PCB, CN3722 should be kept away from the heat source such as diodes, MOSFET, etc. (4) Output capacitor ground connections need to feed into same copper that connects to the input capacitor ground before tying back into system ground. (5) Analog ground and power ground(or switching ground) should return to system ground separately. (6) The ground pins also works as a heat sink, therefore use a generous amount of copper around the ground pins. This is especially important for high VCC and/or high gate capacitance applications. (7) Place the charge current sense resistor RCS right next to the inductor output but oriented such that the IC’s CSP and BAT traces going to RCS are not long. The 2 traces need to be routed together as a single pair on the same layer at any given time with smallest trace spacing possible. (8) The CSP and BAT pins should be connected directly to the current sense resistor (Kelvin sensing) for best charge current accuracy. See Figure 4 as an example.
