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 3.75mm, but with an efficiency of up to 95%, the RBB10-2.0 can operate at full load in ambient Output temperatures as high as 85C 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. Selection Guide Part Input Voltage Nom. Output Output Efficiency Max.
