ROHM Semiconductor has announced the development of the BZ6A series of ultra-compact power supply modules that integrate an inductor, capacitors, and all the other components needed for power supply into a single package. The result is a small size (2.3mm × 2.9mm × 1mm) solution, making it suitable for high-density mounting applications.
In recent years, mobile devices, including smart phones, have become much more multifunctional, increasing the number of components along with the number of power sources needed within the application. The manifold power requirements, along with the trend towards increased miniaturization, demand smaller and more efficient power supplies.
The BZ6A series integrates the BU900xx series IC (a 6MHz high-speed switching DCDC converter) directly into the board and includes all necessary components in a single package. High performance is ensured in a small form factor. The all-in-one configuration eliminates the need for external components, simplifying design and saving development time. Additional features include a wide input voltage range, from 2.3 to 5.5 V, making them suitable for portable devices utilizing a 3V or 5V supply. The fixed output voltage is in the range of 1.0V and 3.3V, ensuring compatibility with a variety of sets. The first available product is a version with 1.2V output.
