The present invention relates to an apparatus including a self-regulating current source, which utilizes a switching regulator to provide high efficiency power conversion and a high-side current monitor, but instead of driving the feedback input with a voltage divider to set the output voltage, the self-regulating current source utilizes a high-side current sense resistor with an operational amplifier optimized for current sensing, to drive the feedback input to the switching regulator, thereby creating a self-regulating constant current source. By adjusting the gain of the operational amplifier, the user can directly set the optimized current needed for using the apparatus in a variety of deployment devices, including satellite and pyrotechnic applications.
