Housed in thin packages, UltraBK converters (MYTNA and MYTNC series) feature a two-stage architecture that combines charge pump technology with conventional DC/DC converter circuits. UltraBK products include both 4- and 6-A devices.

The expanded MonoBK lineup now includes the heat-resistant MYMGK-H series of 12- and 20-A converters. Proprietary packing technology allows for internal temperature reduction of densely-mounted components by leveraging a structure that allows heat to escape from the module substrate.

Low-power PicoBK converters integrate an inductor with a control IC for applications where space is at a premium. These very small modules have low quiescent current, suitable for battery-powered wearable devices. The series comprises 0.5-, 1.0-, 1.5-, and 2.0-A models.

The UltraBK, MonoBK, and PicoBK non-isolated DC/DC converters are in mass production. Data sheets can be found here.
