Description
The R-6xxx series is a high performance 1.5V to 15V (18V), 1.1 Amp to 2Amp, 12-Pin SIP (single in-line package) switching regulator. The Synchronous rectification yields excellent efficiencies up to 97%. Short circuit protection reduces the short circuit input current to under 50mA.

Internal Power Dissipation [W]
How to calculate the max. output current The internal power dissipation (PD ) follows the equation:
PD=
Iout x Vout x (1-Effmax Vin )
Example: R-6212P
Iout=
PD Vout x (1-Effmax Vin )
Calculation 1:
Vin = 32V Vout = 12V Effmax Vin = 93% PD = 1W TAmbient = 60°C
Iout=
1W 12V x (1-0.93 )
= 1.19A
Calculation 2:
Vin = 14V Vout = 12V Eff = 96%
max Vin
PD = 1W TAmbient = 60°C
1W Iout=
12V x (1-0.96 )
= 2.08A
