The TPS610995YFFR starts up from an input as low as 0.7 V and accepts up to 5.5 V, covering single-cell alkaline, NiMH, and Li-ion chemistries down to their end-of-life voltage.
800 mA switch current — sizing the inductor and output power
At 3.6 V output, this translates to roughly 2.5 W output power before the current limit folds back — enough for a Wi-Fi module burst or a string of LEDs. Because the current limit is the switch peak, not the output, the actual load current depends on the inductor ripple and duty cycle. A 2.2 µH to 4.7 µH inductor with a saturation rating above 1 A is typical.
6-DSBGA — footprint and assembly check
Housed in a 6-pin DSBGA (0.9 mm × 1.3 mm typical), the part demands a 0.5 mm ball pitch and a solder-mask-defined pad layout. X-ray inspection is recommended after reflow to confirm ball wetting.
