Compact, low profile buck-boost regulator is quietly efficient with six-sided shielding

Now available from Dengrove Electronic Components, provided as a 25-pad LGA with six-sided shielding, the RECOM RBB10 buck-boost converter is perfect for equipment such as USB voltage regenerators, 3.3V-to-5V converters, and supercapacitor or Li-Ion battery regulators. The all-around shielding improves thermal performance as well as stopping electromagnetic interference. This non-isolated power module is able to supply up to 4A at 5V nominal output voltage, from an input that can range from 2.3V to 5.5V. Reaching up to 96% efficiency, it will run at full load in 85C ambient temperature without forced-air cooling. Measuring 12.19mm x 12.19mm, the device's footprint is compatible with the industry-standard DOSA third-generation, high-density, non-isolated PICO converter specification. Also, at just 3.75mm high, it provides a space-saving solution where an ultra-low profile is needed. An evaluation board, RBB10-2.0-EVM-1, is offered to enable customers in testing the modules. Resistors are offered on-board for trimming the output voltage, as well as break out connectors for choosing operating modes. The board also provides optimal thermal management and a class-B EMI filter layout.
