Despite its compact LGA footprint and low profile (12.2x12.2x3.75mm), it offers a full set of **Single** 2 features including adjustable output from 1V up to 24V, on/off control, sense and power good output signals. With an efficiency of up to 94% which remains nearly constant over a 5% to 100% load range, **Output** the device can operate at ambient temperatures as high as +100°C without forced air cooling. The package is complete with 6-sided shielding for optimal EMC performance and excellent heat management. The fully protected module (UVLO, SCP, OCP, OTP) can drive high capacitive loads of up to 0.2F. |Selection Guide|Selection Guide|||||| |---|---|---|---|---|---|---| |Part|Input Voltage|Output|Vout|Output|Efficiency|Max Capacitive| |Number|Range|Voltage|Adjust Range|Current max.|typ.|typ.

The RPMB-series offers the feature of trimming the output voltage by using external trim resistors. The values for trim resistors shown in trim tables below
are according to standard E96 values; therefore, the specifed voltage may slightly vary. Refer to“Selection Guide“for applicable Vout Adjust Range.
