A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure that the thermal pad is connected to a large copper area to dissipate heat efficiently.
Use a low-ESR capacitor (e.g., 10uF) for decoupling, and ensure that the input and output tracks are short and wide to minimize inductance. Also, consider using a common-mode choke to reduce EMI.
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
Yes, the AMC7823 is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5mA. However, ensure that the device is properly powered down when not in use to conserve battery life.
Check the input voltage, output voltage, and feedback resistors. Ensure that the feedback resistors are correctly connected and that the output voltage is within the specified range. Also, verify that the device is properly decoupled and that the input capacitor is sufficient.
