11 Layout

11.1 Layout Guidelines

  1. Place the decoupling capacitor near the VCC pin and GND plane.
  2. Route the GND pattern as widely as possible for large GND currents.
  3. Routing wire between the LED cathode side and the device OUTn pin must be as short and straight as possible to reduce wire inductance.
  4. When several ICs are chained, symmetric placements are recommended.
