Product details

Dual buck regulator for automotive power rails

The TPS62420QDRCRQ1 is a dual-channel step-down (buck) switching regulator from Texas Instruments, qualified to AEC-Q100 for automotive applications. It delivers 600 mA on one output and 1 A on the other from a 2.5 V to 6 V input rail, with adjustable output voltage down to 0.6 V. The 2.25 MHz switching frequency lets you use small inductors and ceramic output capacitors, which helps keep the PCB footprint tight — useful when you are squeezing two supply rails into a compact ECU or sensor module.

Active production and ordering

It is available in Tape & Reel (TR) or Cut Tape (CT) options for the 10-VSON exposed-pad package. ROHS3 compliant. Sourced per RFQ against your BOM quantity; current pricing and lead time confirmed at quote time.

Frequently asked questions

Is TPS62420QDRCRQ1 a direct replacement for TPS62420DRCR?

The TPS62420QDRCRQ1 is the automotive-grade (AEC-Q100) version of the commercial TPS62420DRCR. Electrical specs — dual output 600 mA / 1 A, 2.25 MHz, adjustable output, same 10-VSON package — are identical. Pin-compatible, but the BOM should specify the grade required.
