The TB6830WBG is a multiple-output DC-DC converter IC that consists of a 2-channel boost
DC-DC converter, a single-channel buck/boost DC-DC converter and a 5-channel
low-dropout (LDO) regulator. Since the TB6830WBG incorporates LDOs, operating modes
can be selected between LDO and buck/boost modes under light-load conditions. The
TB6830WBG is housed in a WCSP package measuring 4.3 mm x 4.3 mm.
