Abstract:
An adaptive power supply module disposed as an interface between a fixed supply voltage source and an associated integrated circuit to be powered, said adaptive power supply module for converting a fixed supply voltage (Vfixed) from said fixed supply voltage source to a predetermined input voltage (Vprog) required to power said associated integrated circuit, said adaptive power supply module comprisingan arrangement for generating a defined reference voltage (Vref) from said fixed, known voltage; a differential amplifier including a first, positive input and a second, negative input and an output, the differential amplifier powered by said fixed, known voltage and the defined reference voltage is applied as an input to the first, positive input; and a resistor divider network, including an internal divided voltage node, coupled between the differential amplifier output and ground potential, wherein said internal node in the divider network is tapped and applied as the second, negative input to said differential amplifier, said differential amplifier output defining the predetermined input voltage to the associated integrated circuit.
