600 mA step-down in a 1.05 x 0.70 mm DSBGA
The Texas Instruments TPS62808YKAT is a 600 mA synchronous step-down buck converter designed for space-constrained, battery-powered applications. The adjustable output range covers 1.8 V to 3.3 V, and the 1.5 MHz switching frequency allows the use of small, low-profile inductors and ceramic capacitors.
Switching frequency and output voltage — sizing the passives
The 1.5 MHz switching frequency supports small inductors and ceramic capacitors. The output voltage is set with a single resistor divider. Synchronous rectification is integrated, eliminating the external Schottky diode and improving efficiency at light loads — a key advantage for always-on IoT endpoints where quiescent current matters.
Temperature grade and package — board-level fit
The 1.05 x 0.70 mm package demands a controlled solder-paste stencil and a reflow profile compatible with fine-pitch BGA.
