The 500 mA continuous output rating is the headline load current — confirm your downstream rail budget stays under this at the lowest input voltage, where the buck-boost duty cycle is highest. ## Switching frequency and external component sizing The 2.5 MHz switching frequency lets you use a 1 µH to 2.2 µH inductor and small 10 µF ceramic capacitors, keeping the total solution area under 15 mm². This is a deliberate trade-off: higher frequency means lower ripple but slightly higher switching losses — the datasheet efficiency curves show ~90% peak at 3.3 V output. ## Sourcing and ordering the exact code The base product number is TPS63051 — the full suffix 'RMWT' encodes the package and reel configuration. Confirm the BOM quantity and preferred packaging before committing; we source and quote to order against your line item.","metaTitle":"TPS63051RMWT Buck-Boost Regulator 3.3V 500mA 12-VQFN","metaDescription":"Texas Instruments TPS63051RMWT — fixed 3.3V output, 500mA buck-boost regulator in 2.5x2.5mm VQFN.
