Design Notes

• In boost mode the input current is continuous but the output current is pulsed; size the output capacitor for the load transient.
• Power switches are integrated, so the thermal path is the PCB copper under the pad.
• Package QFN-13 — check the land pattern in the datasheet before layout.
