6.5 Buck2 (BK2) Switching Regulator
The IS2083BM includes a second build in programmable output voltage regulator which converts the battery voltage to 1.8V, to supply the PMU ADC and to optionally supply stereo audio codec and/or I/O’s. This converter has a high conversion efficiency and a fast-transient response.
Note: Do not connect any other devices to
buck2 regulator output pin (BK2_VOUT).
