The RBB10 power modules are built in Europe to provide trimmed output voltages from a wide range of input voltages in applications such as USB voltage regenerators, 3.3V to 5V converters and battery regulators.

The RBB10 series is a 4A non-isolated buck/boost regulator power module with a 3.75mm profile for space critical applications. Due to its buck-boost operation mode, it accepts input voltages that are higher, equal or lower than the trimmed output voltage. Transition from buck to boost mode is smooth without any interruption to the output.

The module reaches an efficiency of up to 96%, which allows it to operate at full load in ambient temperatures as high as 85°C without forced air cooling. The 6-side shielded package optimizes EMC performance and thermal management for USB voltage regenerators, 3.3V to 5V converters, and supercapacitor or Li-Ion battery regulators. RECOM also developed an evaluation board so that customers will be able to quickly and easily test these modules.

Samples and OEM pricing are available from distributors or directly from RECOM.
