• 1-2AMP adjustable positive step down
integrated switching regulator
• Internal short circuit protection
• ON/OFF control (ground off)
• Efficiency up to 97%
• Positive to negative converter
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.

Iout= PD
Vout x (1-Effmax Vin )
PD= Iout x Vout x (1-Effmax Vin )
The internal power dissipation (PD ) follows the equation:
Vin = 32V
Vout = 12V
Effmax Vin = 93%
PD = 1W
TAmbient = 60°C
Vin = 14V
Vout = 12V
Effmax Vin = 96%
PD = 1W
TAmbient = 60°C
Iout= 1W = 1.19A
12V x (1-0.93 )Iout= 1W = 2.08A
12V x (1-0.96 )

Note6: Requires a 100µF electolytic or tantalum output capacitor for proper operation in all applications
(the capacitor has to be placed as close as possible to the output pins)

Optional Diode Protection Circuit
Add a blocking diode to Vout if current
can flow backwards into the output, as
this can damage the converter when it
is powered down. Protection diodes are
required for high capacitive loads.
The diode can either be fitted across
the device, if the source is low imped-
ance or fitted in series with the output
(recommended). Rdown: Trim output voltage up to 1 diode drop
