DC/DC Converter

Description

The RBB10-2.0 series is a 4A non-isolated buck/boost regulator power module where the input voltage

can be higher, lower or same as output voltage. Transition from buck to boost mode is smooth without

any interruption to the output. The compact DOSA-compatible footprint module has a low proﬁle of

only 3.9mm, but with an efﬁciency of up to 95%, the RBB10-2.0 can operate at full load in ambient

temperatures as high as 85°C without forced air cooling. The package has 6-sided shielding for

optimal EMC performance and excellent thermal management. Typical applications include USB voltage

regenerators, 3.3V<->5V converters and supercapacitor or Li-Ion battery regulators.

RBB10-2.0 DC/DC Converter Series Specifications (measured @ Ta= 25°C, 5Vin, 5Vout, 2A and after warm-up unless otherwise stated) OUTPUT VOLTAGE TRIMMING The RBB10-2.0 series offers the feature of trimming the output voltage over a range between 1.0V and 5.5V by using external trim resistors. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.
