ABSTRACT:
A power supply configured to receive and provide a 10V input, 5V output with a continuous load of 1 A load current and a pulse load duration of 2 ms and a pulse load of 10 A load current including a switching regulator configured to provide a continuous current, the switching regulator comprising a current limit of 1.2 A, a linear regulator associated with the switching regulator, and a control circuit configured to direct the linear regulator to provide a minimal current when the power supply is at a continuous load, and to direct the linear regulator to provide a remaining portion of a pulse load current from the continuous load of the switching regulator. The control circuit, in a condition that a noise-free mode is demanded, deactivates the switching regulator and directs the linear regulator to provide the continuous current.
