R-551.8DA
)
The R-5xxxA series is a high performance 1.2V to 5.5V, 2Amp to 5Amp, 12-Pin SIP (single in-line package) integrated switching regulator (ISR). The synchronous - rectified design yields excellent efficiencies up to 96%. Short circuit protection reduces the short circuit input current to under 50mA. Autosense function compensates for any losses in long circuit loops.

Yes you can. Please refer to the Innoline Application Notes and find our recommended circuits to get a negative output from each series of our switching regulator families.
No. Switching regulators function differently than linear regulators and this “trick” does not work. They need a very good ground connection to function properly.
The Innoline series all use intelligent controllers that measure the output current on each switching cycle (Current Mode Control). If the output is overloaded, the converter will deliver the over-current until either the converter overheats and shuts itself down (thermal protection) or the load current exceeds the safe limits. If the output is short circuited, the controller shuts down the output drive circuitry. The output condition is continuously monitored and the converter automatically restarts.
