- Page 10 MIC33M350 Evaluation Board User’s Guide MIC33M350 EVALUATION BOARD DESCRIPTION The MIC33M350 Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MIC33M350 module. The MIC33M350 Evaluation Board demonstrates MIC33M350’s capabilities in a buck converter application, supplied from an external voltage source (2.4V-5.5V) to pin programmed regulated output. Two jumpers are provided to select the desired output voltage from nine preset values.
- Page 11 Chapter 2. Installation and Operation INTRODUCTION The MIC33M350 device has been developed for applications suited for 2.4V to 5.5V input voltage range, low shutdown, quiescent currents and high continuous output current. These characteristics make the MIC33M350 device ideal for single cell Li-Ion battery-powered applications.
- Page 12 Connect the positive voltage terminal of the load to the “VOUT” terminal on the MIC33M350 Evaluation Board and connect the negative or the return side of the load to the ground terminal, “GND_OUT”. Make sure the three provided jumpers are readily available.
- Page 13 7. Remove the enable jumper (“J5”) and check the reading on the ampere meter. The measured shutdown current should be less than 10 µA. V-METER LOAD OSCILLOSCOPE A-METER + POWER – SUPPLIY FIGURE 2-2: MIC33M350 Evaluation Board Setup. 2020 Microchip Technology Inc. DS50002990A-page 13...
