Product details

What this 1.2 A buck regulator delivers in a 3×3 mm footprint

The TPS62040DRCR is a synchronous step-down (buck) regulator from Texas Instruments, rated for 1.2 A continuous output current in a 10-VSON (3x3) package — a footprint that fits tight point-of-load slots on multi-rail boards. Switching at 1.25 MHz, it lets you use small-value inductors and ceramic output capacitors, shrinking the total converter area while keeping ripple under control. The output is adjustable from 0.7 V up to the input voltage (max 6 V), covering the core voltages of modern MCUs, FPGAs, and DSPs.

Output range, temperature grade, and synchronous rectification

Output voltage is set with an external resistor divider from a 0.7 V reference — the adjustable range runs from 0.7 V to 6 V, matching the 2.5 V to 6 V input supply window.

Sourcing posture and package availability

ROHS3 compliant per, with no known obsolescence risk.

Frequently asked questions

What output voltage range does TPS62040DRCR support?

The input supply range is 2.5 V to 6 V.

Can TPS62040DRCR be used for a 3.3 V output?

Yes — set the feedback resistor divider so that Vout = 0.7 V × (1 + R1/R2). A 3.3 V output is well within the 0.7 V to 6 V adjustable range.

What package does TPS62040DRCR come in?

It is supplied in a 10-VFDFN exposed-pad package (10-VSON, 3×3 mm).

How does TPS62040DRCR compare to the LMR33630APCQRNXRQ1?

The TPS62040DRCR is a general-purpose industrial part at 1.2 A and 1.25 MHz. For a 1.2 A non-automotive rail, the TPS62040 is the direct fit; the LMR33630 is an over-spec alternative if you need higher current or automotive qualification.
