TPSM8A29EVM Bill of Materials

A complete bill of materials (BOM) is shown in Section 8. Resistors may be substituted as required so long as tolerance and temperature coefficients are considered. Capacitors may be substituted as required so long as dielectric, voltage ratings, and derating are considered. TI makes no guarantees about component availability.
