A good PCB layout for the MAX9928FAUA+T involves keeping the input and output traces short and separate, using a solid ground plane, and placing the device close to the battery. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The choice of external components for the MAX9928FAUA+T depends on the specific application requirements. For example, the input capacitor (CIN) should be chosen based on the input voltage and current requirements, while the output capacitor (COUT) should be chosen based on the output voltage and current requirements. The datasheet provides guidelines for selecting these components.
The MAX9928FAUA+T is rated for operation over a temperature range of -40°C to +125°C. However, the device's performance may degrade at extreme temperatures, and the maximum junction temperature should not exceed 150°C.
The MAX9928FAUA+T has a specific power-up and power-down sequence that should be followed to ensure proper operation. The device should be powered up by applying a valid input voltage to the VIN pin, and powered down by removing the input voltage. The datasheet provides more information on the power-up and power-down sequences.
The MAX9928FAUA+T is designed to meet EMI and EMC standards, but proper PCB layout and component selection are still important to minimize electromagnetic interference. The device's switching frequency can be adjusted to minimize EMI, and shielding and filtering may be necessary in some applications.
