Product details

Fixed 1.2 V rail for low-power digital loads

The TPS62207DBVT is a fixed-output buck converter delivering 1.2 V at up to 300 mA from a 2.5 V to 6 V input bus — ideal for powering a 1.2 V core rail on an MCU, FPGA, or sensor ASIC.

Synchronous rectification cuts BOM count

The 300 mA output is the continuous ceiling; derate for ambient above 85°C per the datasheet thermal impedance curves for the SOT-23-5 package.

Industrial temperature range — 85°C ceiling

Not suited for under-hood or engine-bay environments where 125°C-rated parts are required.

Frequently asked questions

Does TPS62207DBVT output a fixed 1.2 V?

Yes, the output is fixed at 1.2 V — no external resistor divider needed for the feedback. The output type is Fixed.

Can TPS62207DBVT run from a 5 V input?

Yes — the input voltage range is 2.5 V to 6 V, so a 5 V supply is well within the operating window. The 6 V maximum means it cannot tolerate a 12 V or 24 V bus.

What is the closest functional second-source to TPS62207DBVT?

The LM53625LQURNLRQ1 is an automotive-grade (AEC-Q100) buck converter with 2.5 A output and 2.1 MHz switching, but its 3.9 V minimum input and larger package (Wettable Flank QFN) make it a different fit. No direct pin-compatible second-source exists for the TPS62207DBVT.
