NON-ISOLATED DC/DC CONVERTERS
8.3 Vdc - 14 Vdc Input
0.75 Vdc - 5.0 Vdc/3 A Output
Remote Enable Specifications
The SRBA-03A1AL modules feature an enable
pin with negative logic. If not using the enable
pin, leave the pin open (the module will be on).
During logic_high, the module is turned off,
during logic_low, the module is turned on. It inner
circuit impedance is showed as figure.
SRBA-03A1AL
The SRBA-03A1A0 modules feature an enable
pin with Positive logic. If not using the enable pin,
leave the pin open (the module will be on).
During logic_high, the module is turned on,
during logic_low, the module is turned off. It inner
circuit impedance is showed as figure.

Output Trim Equations
Equation for calculating the trim resistor (in k ? ) given the desired adjusted voltage (Vadj) is shown below. The
Trim Up resistor should be connected between the Trim pin and Ground.
