Notes:  
1. Requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications (the capacitor to be placed as close as possible to the output pins).  
2. ON / OFF pin can be driven by TTL (logic gate), open-collector bipolar transistor or open-drain MOSFET.  
3. Output Current vs. Input Voltage (see graph below).

Input Voltage (V)  
Internal Power Dissipation (W)  
Max output current calculation:  
Internal power dissipation  
(1W) = Io x Vo x (1-Efficiency)  
Io = 1(W) / Vo x (1-Efficiency)  
Example : R-6212P  
at Vin = 28VDC  
at Vin = 14VDC  
Efficiency = 96% (see ”Selection Guide” table)  
Vo = 12Vdc  
Io = 1W / 12V x (1-0.96) = 2.08A (spec. = 2A max.)  
Efficiency = 94% (see ”Selection Guide” table)  
Vo = 12VDC  
Io = 1W / 12V x (1-0.94) = 1.388A = 1.5A
