PCB Layout Guide

If you need low Tc and Tj or large PD (Power Dissipation), the dual SW pins (5 and 6)

on the SOP-8L package are internally connected to die pad, The PCB layout should allow

for maximum possible copper area at the SW pins.

1. Connect C3 to VCC pin as closely as possible to get good power filter effect.

2. Connect R3 to VCC pin as closely as possible.

3. Connect ground side of the C2 and D1 as closely as possible.
