2A buck-boost in a 15-bump DSBGA
The TPS63806YFFR is a synchronous buck-boost regulator from Texas Instruments that delivers up to 2A continuous output current from a 1.3V to 5.5V input range, with an adjustable output spanning 1.8V to 5.2V. The 2.1MHz switching frequency keeps external inductor and capacitor values small, suiting space-constrained designs like battery-powered portable equipment or multi-rail IoT modules. The 15-bump DSBGA package (0.4mm pitch typical) requires a controlled SMT profile and a clean board layout to manage thermal and noise — not a hand-solder part.
2.1MHz switching and 125°C junction rating
Switching at 2.1 MHz lets the design use a smaller inductor (typically 1 µH to 2.2 µH range) compared to a 500 kHz part, at the cost of slightly higher switching losses.
