2.5 A in a 2.24×2.16 mm footprint — the space-constrained power decision
The TPS62362YZHR is a 2.5 A synchronous step-down (buck) converter from TI's DCS-Control family, packing its output stage into a 16-bump DSBGA that measures 2.24×2.16 mm. The 2.5 MHz switching frequency lets you drop the inductor to the 1 µH range and use small ceramic caps, which is the whole point when board area is the constraint — think handheld instruments, wireless modules, or sensor nodes where every mm² counts.
Programmable output — fixed presets save a resistor divider
Output voltage is adjustable from 0.77 V up to 1.4 V, with factory-programmed fixed options at 1 V, 1.1 V, 1.2 V, and 1.23 V. For a design targeting a 1.2 V core rail, you skip the external feedback divider entirely — one less pair of 0402s on the layout, and no tolerance stack-up on the setpoint.
Industrial temperature grade — not just a bench part
Sourcing and lifecycle — active, but the package limits alternatives
For production, qualify the part early and secure a franchise-distribution allocation; the spot market for DSBGA devices tends to be thin when lead times stretch.
