Layout Guidance
If you need low Tc & Tj or large PD (Power Dissipation), The dual SW pins (5&6) and Gnd pins (7&8) on the SOP-8
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 V_CC and Gnd pin as closely as possible to get good power filter effect.
2. Connect R3 to V_CC and OCSET pin as closely as possible.
3. Connect ground side of the C2 & D1 as closely as possible.
