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).

Internal Power Dissipation (W)
1.5
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
Efficiency = 94% (see ”Selection Guide” table)
Vo = 12VDC
Io = 1W / 12V x (1-0.94) = 1.388A = 1.5A
at Vin = 14VDC
Efficiency = 96% (see ”Selection Guide” table)
Vo = 12Vdc
Io = 1W / 12V x (1-0.96) = 2.08A (spec. = 2A max.)
