## Datasheet

📄 [Download PDF](https://novapart.co/datasheet/farnell:3977343/)

Features • 10W buck/boost converter with up to 4A output • Input voltage can be higher, lower or same as output voltage Power • >90% efficiency from 100mA – 3000mA load • 7µA standby power consumption Module • Low profile, thermally enhanced 25pad LGA package ee Lo 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.

## 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.

## Notes: 

Note6:  The RBB10 has the possibility to work in two regulation modes: 

Powersave Mode (standard): This mode is the best for use at low loads to reduce power consumption and extend battery life. In this mode the internal power  consumption is reduced by using burst mode for loads under 350mA and PWM for loads above 350mA. The drawback is a 1-3 % higher output voltage at low load than full load. 

Fixed PWM mode: In PWM mode the device accurately regulates the output voltage independently of the load current. The drawback is a higher internal power consumption and shorter battery life at lower loads. Pull down the Mode pad to GND to enter this mode.
