2.5 A in a 2.24×2.16 mm DSBGA — power density for tight boards
The TPS62366AYZHR is a 2.5 A continuous-rated step-down buck converter from Texas Instruments, built around the DCS-Control™ topology. It switches at 2.5 MHz, which lets the designer use a small inductor and low-value ceramic output capacitors — the whole converter fits in a 16-bump DSBGA package that measures 2.24×2.16 mm. That combination of output current and footprint targets space-constrained, battery-powered applications where every mm² of board area is budgeted.
Programmable output rail — 0.5 V to 1.77 V, plus fixed taps
The output is adjustable from 0.5 V up to 1.77 V, with factory-programmable fixed options at 1.16 V and 1.2 V. That voltage range covers the core supplies for many low-power processors, FPGAs, and wireless SoCs. Synchronous rectification is built in — no external Schottky diode needed, which saves one component and keeps the layout tight.
It fits portable instruments, IoT gateways, handheld medical devices, and outdoor telecom modules that see cold starts but stay below the under-hood thermal profile. The 2.5 MHz switching frequency pushes the first switching harmonic beyond the AM radio band, which helps with EMI compliance in consumer and industrial enclosures.
The base product number is TPS62366, and the YZHR suffix identifies the DSBGA package and tape-and-reel delivery.
