Fixed 1.5 V rail — no divider resistors
The TPS62042DRCR is a fixed-output buck converter from Texas Instruments that delivers 1.2 A at 1.5 V from a 2.5 V to 6 V input rail. Because the output is fixed, the BOM saves two feedback-divider resistors and the associated PCB area — a clean drop-in for a 1.5 V logic or sensor supply.
1.2 A at 1.25 MHz — inductor sizing
The 1.25 MHz switching frequency lets you use a small inductor (typically 2.2 µH to 4.7 µH range) and small ceramic output capacitors, keeping the total solution footprint tight.
