Shared Pin Mapping for SD Card and NAND Flash Interfaces on MPU I am using this MPU SOM Module and this NAND Flash device for storing the boot image. I will also use a 4-bit SD card interface with the MPU for data logging. I’m reviewing the MPU datasheet (link above) and have some confusion regarding the pin mapping for the SD card and NAND flash interface... (more) |

Determination of Target Frequency in PDN Decoupling There is a plan to do PDN decoupling simulation for the KSZ9897RTXI power rails. It has various power supply like 1.8V, 2.5V& 1.2V. While doing the simulation, what is the maximum frequency range to be considered, so that the impedance should be below the target limit. (more) |

@Olin Lathrop: There was an electronic load on the output that was enabled and set to 8A. Essentially, the regulator was to come up under load. One other note, it is possible voltage was present on the FREQ pin while the regulator input was at 0V during this test. (more) |

Regulator Failure on Load Enable – Thermal Stress or Inrush Condition? We perform a test on this device where the regulator input power is enabled with an 8A load connected to the output, while the device itself remains disabled. We then drive the EN pin high to enable the device under load. In one of our boards, this resulted in the regulator overheating and sho... (more) |

Unexpected High Quiescent Current in Step-up converter with Fast EN Cycling We’ve been working with the this boost regulator and set it up according to the attached schematic. To minimize power consumption, the approach was to enable the boost once every 31.25 ms: we pull the EN pin high (‘1’), take a reading, and then switch it off again. During analysis, we noticed ...
