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.)
