Overview
The MIC23158/9 Evaluation Board has been developed to evaluate the capabilities of the MIC23158/9 family of devices. The board is populated with the MIC23159 device and it’s set for the following voltages:
•Regulator 1: 1.8V.
•Regulator 2: 1.5V.
The evaluation board can be easily modified by interchanging the MIC23159 device with MIC23158.
The MIC23158/9 Evaluation Board features independent Enable connectors with individual pull-up resistors.
To check the status of each regulator, power-good connectors are available for each regulator. The board can be powered from two independent voltage sources or a 0Ω resistor can be placed on R3 so that both converters be powered form the same voltage source.
