Rohm claims its recently announced power supply is the world’s smallest, at just 2.3 x 2.9 x 1 mm. The BZ6A series of ultra-compact power supplies integrate an inductor, capacitors, and all the other components needed for a power supply into this single tiny package, making them suitable for high-density mounting applications.
The BZ6A series integrates a BU9000X series 6MHz high-speed switching power supply LSI with all the necessary components in a single package, boasting 85%+ efficiency. The all-in-one configuration eliminates the need for external components, simplifying design. Additional features include a wide input voltage range from 2.3V to 5.5V, making the power supplies suitable for portable devices using 5V USB, as well as an output voltage range between 1.0V and 3.3V.
