Product details

3V to 17V input, fixed 5V rail — the BOM-fit check

The Texas Instruments TPS62153RGTT is a synchronous step-down (buck) regulator from the DCS-Control family, delivering a fixed 5V output at up to 1A from a 3V to 17V input rail. It integrates the synchronous rectifier, so no external Schottky catch diode is needed — the BOM stays tight for a 5V point-of-load rail.

2.5 MHz switching — inductor sizing and layout trade-offs

Switching at 2.5 MHz lets you pick a small inductor — typically 1 µH to 2.2 µH range — which saves board area on a 16-VFQFN (3x3) footprint. DCS-Control topology gives fast transient response without external compensation components — the loop is internally compensated, so you don't spend BOM lines on RC networks.

The 16-VFQFN package with exposed pad (3x3 mm) is a current-generation footprint — no pinout obsolescence risk against newer TI buck converters in the same package family.

Frequently asked questions

Is TPS62153RGTT pin-compatible with TPS62152?

Yes, they are pin-compatible. The TPS62152 is the adjustable-output version (0.9V to 6V via external resistor divider), while the TPS62153RGTT is the fixed 5V output variant. Same package, same pinout — you can swap them on the same PCB layout if you change the feedback network for the adjustable version.

Does TPS62153RGTT require external compensation?

No. The DCS-Control topology features internal compensation. The only external components needed are the input and output capacitors and the inductor — no RC compensation network on the BOM.
