Product details

The Texas Instruments TPS62161DSGT is a synchronous step-down (buck) regulator that delivers a fixed 1.8V output at up to 1A from a 3V to 17V input rail. It uses TI's DCS-Control topology.

1A output — sizing the load budget

The 1A continuous output current is the hard ceiling for the load. The synchronous rectifier helps efficiency at light loads.

Input range and output voltage — what the numbers mean

The 3V minimum input and 17V maximum cover a range of supply rails. The output is fixed at 1.8V.

Surface-mount assembly is standard.

For dual-sourcing resilience, the LM53625LQURNLRQ1 is a functional peer — same buck topology, 2.1 MHz switching, 2.5 A output, but automotive-qualified (AEC-Q100) and in a wettable-flank package. It is not a pin-for-pin drop-in, but a valid alternative for a second-source qualification effort.

Frequently asked questions

Can TPS62161DSGT replace TPS62160?

The TPS62161 has a fixed 1.8V output, while the TPS62160 is adjustable. They share the same package and pinout, so the TPS62161 can replace the TPS62160 only if the fixed 1.8V output matches your design. For other output voltages, use the TPS62160.

What is the replacement or equivalent for TPS62161DSGT?

The LM53625LQURNLRQ1 is a functional peer — same buck topology, 2.1 MHz switching, 2.5 A output, automotive AEC-Q100 qualified. It is not a pin-compatible drop-in but a valid second-source candidate for qualification.
