APPLICATION INFORMATION
layout and board space
All capacitors should be soldered as close as possible to the IC. A PCB layout proposal for a single-layer board
is shown in Figure 37. Care has been taken to connect all capacitors as close as possible to the circuit to achieve
optimized output voltage ripple performance.
