Two switching frequency options — 1 MHz or 2.5 MHz — let you prioritise efficiency (lower frequency) or inductor footprint (higher frequency). The adjustable output covers 0.4 V to 5.5 V, so it can feed a 1.8 V core rail or a 3.3 V I/O rail from the same BOM line.
The suffix difference typically indicates packaging or reel quantity variation. Both share the same base product number TPS629210 and the same electrical specifications — confirm the exact reel quantity and tape format with your distributor before ordering.
The device operates at either 1 MHz or 2.5 MHz, selectable via the FSEL pin or external resistor.
