LightProbe - Ultracompact Power Supply PCB

Short Description

In the DigitalUltrasoundHead (now LightProbe) project we are building a digital ultrasound transducer head, which incorporates the entire ultrasound analog frontend. The frontend requires around 10 different supply voltages up to +-50V, which need to be turned on/off in the right sequence. To reduce the number of external supplies, we want to generate all required voltages within the head, which imposes critical space constraints on the power supply PCB size. For aggressive power management, some supplies must be able to be turned off quickly and in the right sequence. A dedicated controller will be used to generate the control signals for proper sequencing.

In this semester project, you are going to design a ultra-compact power supply PCB (max ~3x5cm) using standard components. A basic schematic will be provided as a starting point. You will also have to design the controller responsible for proper sequencing.

This is a classic engineering project and ideal if you want to deepen you PCB design skills. Having done the PCB course is sufficient. No power electronics background required.
