2.5 A buck in a 2.24x2.16 mm DSBGA
The TPS62361BYZHT is a 2.5 A continuous-rated step-down converter from TI's DCS-Control family, switching at 2.5 MHz to keep the inductor and output capacitor physically small — a deliberate trade-off for space-constrained portable or battery-powered designs. Output is adjustable from 0.5 V up to 1.77 V, with factory-programmable preset voltages at 0.96 V, 1.16 V, and 1.4 V — covering common core rails for low-voltage processors and FPGAs without external resistor dividers. The 16-DSBGA package (2.24x2.16 mm) demands a controlled solder-paste stencil and careful thermal management — the copper pad area under the die sets the junction-to-ambient thermal resistance.
Switching frequency and output range
At 2.5 MHz the TPS62361BYZHT operates well above the AM broadcast band, so the switching noise couples into the output ripple rather than the radio front-end — a practical advantage for handheld wireless gear.
