Step 6: From Table 10 a 3A Schottky diode must be selected. For surface mount diodes with a margin of safety
on the voltage rating one of five diodes can be used:
SK34
30BQ040
30WQ04F
MBRS340
MBRD340
Step 7: A 0.01μF capacitor will be used for Cboost.
VSON PACKAGE DEVICES
The LM2670 is offered in the 14 lead VSON surface mount package to allow for a significantly decreased
footprint with equivalent power dissipation compared to the DDPAK. For details on mounting and soldering
specifications, refer to Application Note AN-1187 SNOA401 at
www.ti.com/lsds/ti/analog/powermanagement/power_portal.page.
