OSTI ID:954213
A temperature stabilized, digital input circuit module using surface mount technology has been developed for use as the precision control element in a 10 A. bipolar trim magnet regulator. Regulators using this module have shown stability of 20 ppm over 8 hours. This circuit module combines the functions of a current measuring shunt, serial DAC, precision voltage reference, high gain error amplifier and readback buffer amplifier. Loop gain and compensation are done externally to the module. The module can be used in high current power supplies by replacing the internally derived current signal with the output signal from an external high current shunt or transductor.
