The EVK includes a number of programable current sources and switched resistive loads on board.   Net names: SD3 - BUCK3 Output. VIL_SD3 - Output of the current shunt amplifier for Buck3's programable current sink.   BUCK 3 - Configuration Buck 3 is left in its default configuration for a 900 mV output. (BUCK3) SD3 - 0 A to 1 A (BUCK3) SD3 - 100 mA to 1 A (BUCK3) SD3 - Random 0 mA to 2.2 A   LDO2 PSRR For this test we will evaluate how well LDO2 can post regulate the o ...
The 32.768 kHz crystal oscillator is a popular low-power clock source for many sub-systems in an electronics design. Frequent users of the 32K clock include: Real Time Clock (RTC), processor, RF modems/transceivers, and GPS receivers, just to name a few. Given the large number of potential consumers of a 32K clock in an electronics design, the MAX77714 provides 3 configurable 32K clock outputs on GPIO4 to GPIO6. To enable a 32K clock output in the MAX77714 EVK GUI, one must first enable Alternat ...
My RoadTest of the MAX77714 EVK just keeps getting more bizarre. Both of the push button switches on my EVK fail to operate. A few weeks ago I was briefly experimenting with the soft power button features and couldn't get it work. Turns out, it is because the push buttons are defective. I have recently discovered this trying to document my failing 32K crystal oscillator. I wanted to reset the PMIC to confirm my memory of the sequence of events that transpired trying to get the 32K oscillator to ...
This page is a collection of snippets for the RoadTest of the MPM54304 <link to final review>   In this road test I aim to answer the following 2 questions: (1) How is the MPM54304 programed the first time? (2) How well do the software tools provided by MPS aid in the design, integration, and validation of an electronically programmable power solution?   For the purposes of RoadTesting the MPM54304, I will attempt to employ the programable DCDC converter into a multi-rail &ldqu ...
