LM3464AMH/NOPB Frequently Asked Questions (FAQs)
Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to minimize thermal resistance. A thermal pad on the bottom of the package should be connected to the ground plane.
To ensure reliable start-up and operation, it is recommended to add a soft-start circuit to limit the inrush current and prevent voltage drops on the input supply. Additionally, a voltage supervisor or reset IC can be used to monitor the input voltage and ensure the device is operating within the recommended range.
The maximum output current capability of the LM3464AMH/NOPB is dependent on the input voltage, output voltage, and thermal conditions. However, as a general guideline, the device can deliver up to 1.5A of output current with a 12V input and 5V output, and up to 3A with a 12V input and 3.3V output, assuming a reasonable thermal design.
To minimize EMI, it is recommended to use a shielded inductor, keep the switching node (SW pin) as short as possible, and use a common-mode choke or EMI filter on the input and output lines. Additionally, a snubber network can be added to reduce the voltage ringing on the SW pin.
Texas Instruments recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the input voltage and output current requirements. The capacitor should be placed as close as possible to the VIN pin to minimize the input impedance.
