Product details

What this buck converter does and where it goes

The TPS62736RGYT is a step-down (buck) converter from Texas Instruments, rated for 50 mA continuous output current — a fit for low-power wireless nodes, energy-harvesting front ends, or any battery rail that needs to drop 2 V–5.5 V input down to a programmable 1.3 V–5 V output.

When you're reworking this on a bench, set your hot-air station to a profile that heats the pad evenly — the thermal mass of the pad pulls heat faster than the peripheral pins, so if you rush it you risk lifting the pad or delaminating the board. The tight 0.5 mm pitch means a good stencil alignment and a controlled reflow profile matter more than solder volume.

Lifecycle status and how to source it

Frequently asked questions

Is TPS62736RGYT pin-to-pin compatible with TPS62740?

No — the TPS62740 is a different part with a higher current rating (300 mA) and a different pinout. They are not drop-in replacements; verify the layout before swapping.

What is the switching frequency of TPS62736RGYT?

It operates at a fixed 2 MHz, which allows a small inductor and keeps ripple manageable for a 50 mA load.

What is the closest functional second-source to TPS62736RGYT?

The LMR33630APCQRNXRQ1 is a 3 A automotive-grade buck from TI, but it is not a functional replacement — its output current is 60× higher, its package is different, and it targets a different application space. For a 50 mA low-power rail, the TPS62736RGYT is the correct choice.
