R-6xxxP_D
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.

How to calculate the max output current
The internal power dissipiation (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
Effmax Vin = 96%
PD = 1W
TAmbient = 60°C
