14 / 21 page  SC623 14 PCB Layout Considerations The layout diagram in Figure 1 illustrates a proper two-layer PCB layout for the SC623 and supporting components. Following fundamental layout rules is critical for achieving the performance specified in the Electrical Characteristics table. The following guidelines are recommended when developing a PCB layout: Place all bypass and decoupling capacitors — C1, C2, CIN, and COUT as close to the device as possible. All charge pump current passes through VIN, VOUT, and the bucket capacitor connection pins. Ensure that all connections to these pins make use of wide traces so that the resistive drop on each connection is minimized. The thermal pad should be connected to the ground plane using multiple vias to ensure proper thermal connection for optimal heat transfer. • • • Applications Information (continued) Make all ground connections to a solid ground plane as shown in the example layout (Figure 3). If a ground layer is not feasible, the following groupings should be connected: PGND — CIN, COUT AGND — Ground Pad If no ground plane is available, PGND and AGND should be routed back to the negative battery terminal as separate signals using thick traces. Joining the two ground returns at the terminal prevents large pulsed return currents from mixing with the low-noise return currents. • • • COUT C1 C2 CIN BL1 BL2 C2- SWIF SC623 FL GND GND NC NC PGND NC NC Figure 1 — Recommended PCB Layout Figure 2 — Layer 1 Figure 3 — Layer 2 |
