Micro converters in the series have a footprint of only 2.9 × 2.3 mm and an insertion height of 1 mm. The modules accommodate an input voltage range of 2.2V to 5.5V. Comprising eight models, the B30000P80 series offers output voltages ranging from 1.10V to 2.80V and maximum output current of 600 mA. All converter modules employ overload protection and will shut down automatically at excess temperatures. Their efficiency of 92% makes them well-suited for battery-powered devices.

Under light loads, the modules operate in power-save mode using pulse frequency modulation, with a typical quiescent current of 24 µA. The converters can be shut down using an enable input. In this case, the supply current drops to below 1 µA. They also feature fast load transient response and low ripple voltages and currents. Devices operate over a temperature range of –40° to +85°C.
