Buck-boost converter has low profile and EMC optimised package

Designed for space-critical applications, the low profile RBB10 buck-boost converter from Recom has a DOSA footprint.

The power modules can provide trimmed output voltages from a range of input voltages in applications such as USB voltage regenerators, 3.3V to 5.0V converters and battery regulators.

The RBB10 series is a 4.0A non-isolated buck-boost regulator power module with a low profile. The buck-boost operation mode allows it to accept 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 compact RBB10 module reaches an efficiency of up to 96 per cent, which allows it to operate at full load in ambient temperatures as high as 85 degree C without forced air cooling. The six-side shielded package optimises EMC performance and thermal management.

The converter module can be used in USB voltage regenerators, 3.3V to 5.0V converters, and supercapacitor or Li-Ion battery regulators. Recom has also developed an evaluation board to test the modules.

RBB10 samples are available now from authorised distributors or directly from Recom.

Recom Power supplies a range of DC/DC and AC/DC converters in every power class up to 960W alongside switching regulators and LED drivers in a selection of designs. It introduced the R-78 switching regulators which have become industry standard.

Recom’s headquarters in Gmunden, Austria, include a logistics centre and laboratory wing. Recom has an international distribution network to deliver the company’s products to customers.
