Product details

Why the -55°C to 210°C range matters

The TPS62000SHKK is a Texas Instruments adjustable step-down buck regulator rated for a continuous operating junction temperature from -55°C to 210°C — not a typo, and not the standard TPS62000 part. That 210°C ceiling puts it into the downhole, avionics engine-bay, and satellite-bus tier where commercial plastic-packaged regulators fail. The 300 mA output current is modest, but the thermal headroom is the point: this part keeps running when the ambient is well above 125°C.

Ceramic flatpack — not your usual SOIC

The 10-CDFF (ceramic dual flatpack) package is a hermetic, high-temperature construction. This is not a standard TSSOP-8 or SOIC-8 footprint — the ceramic body and lead frame handle the 210°C junction temperature without the epoxy delamination you would see in a plastic package.

750 kHz switching — inductor sizing

The 750 kHz fixed switching frequency sets the inductor value and output ripple. Output voltage is adjustable from 0.8 V up to 5.5 V via an external resistor divider.

The base product number is TPS62000; the SHKK suffix identifies the high-temperature ceramic flatpack variant.

Frequently asked questions

Is TPS62000SHKK equivalent to TPS62000?

Functionally yes — both are the same base TPS62000 adjustable step-down regulator with 300 mA output and 750 kHz switching. The difference is the package and temperature grade. The standard TPS62000 comes in a plastic TSSOP-8 with a commercial or industrial temperature range. The SHKK variant uses a hermetic 10-CDFF ceramic flatpack rated for -55°C to 210°C. They are not pin-compatible — the ceramic flatpack has a different footprint and lead configuration.

What is the output current rating of TPS62000SHKK?

The continuous output current rating is 300 mA. This is a low-to-moderate current regulator — suited for powering sensor front-ends, reference supplies, or low-power digital rails in extreme-temperature systems, not for high-current loads.

What is the switching frequency of TPS62000SHKK?

The switching frequency is 750 kHz. This fixed frequency allows the use of small-value inductors (4.7 µH to 10 µH typical) and keeps the output ripple manageable. The integrated synchronous rectifier eliminates the external catch diode.
