Microchip Technology MIC23158/9 Evaluation Board
Microchip Technology MIC23158/9 Evaluation Board can be used to develop and evaluate the MIC23158/9 Switching Voltage Regulator's capabilities. The board comes with the MIC23159 device and is set for regulators 1: 1.8V and 2: 1.5V. The MIC23158 can easily be added to the board by interchanging the MIC23159 device. 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 from the same voltage source.
