Power-Supply Design Step 3: Circuit Design of Individual DC-DC Converters. Step 3 is the circuit design. The external, passive components need to be selected for the chosen switching-regulator IC.

A previous Design Idea (Reference 1)describes a three-IC control circuit for testing the power sequencing of an SOC (system on chip). Although that circuit lets you control the power-on sequence of ...

These power-supply circuits will work with MAX86141-based PPG devices as well. In Part 2, we present pre-validated integrated power-supply circuits for use with both MAX86171- and MAX86141-based ...
