The boost output delivers up to 2.4 A; the LDO output is programmable.
The boost converter switches at either 500 kHz or 1 MHz — the higher frequency shrinks the inductor but increases switching losses.
The base product number is TPS65235; the -1RUKR suffix identifies this specific 20-WQFN variant.
It is supplied in a 20-WFQFN with an exposed pad, also designated 20-WQFN (3x3).
