Product details

2.4 MHz switching frequency — inductor size vs efficiency

The TPS62A01ADRLR switches at 2.4 MHz, which lets you use a physically smaller inductor compared to a lower-frequency regulator. The trade-off is slightly higher switching losses, but for a 1 A rail in a space-constrained board the smaller inductor usually wins. With a 1 A output rating in the SOT-563 package, the thermal limit is set by the copper area on the PCB.

Input and output voltage range — rail compatibility

Because it is a synchronous buck with the rectifier integrated, you do not need an external Schottky diode. That saves one component and one placement, which matters when the board is already dense.

It is offered in Tape & Reel and Cut Tape options.

Frequently asked questions

How can I order TPS62A01ADRLR or check current pricing?

Submit an RFQ with your target quantity; we confirm availability and current pricing per order — no stock-holding claim, sourced per request.

Does TPS62A01ADRLR work with a 5 V input to produce a 3.3 V output?

Yes. At 1 A load the 2.4 MHz switching frequency keeps the inductor small.
