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.
