A good PCB layout for the MAX77387EWP+T involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
To ensure the stability of the output voltage, it is essential to choose the correct output capacitor value and type. A minimum capacitance of 10uF with an ESR of 1ohm or less is recommended. Additionally, the output capacitor should be placed close to the IC to minimize the loop area and reduce noise.
The MAX77387EWP+T can handle a maximum input voltage of 5.5V. Exceeding this voltage may damage the IC. It is essential to ensure that the input voltage is within the recommended range to ensure the reliability and longevity of the device.
The output voltage of the MAX77387EWP+T can be programmed using an external resistor divider network connected to the FB pin. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1/R2 + 1), where R1 and R2 are the resistors in the divider network.
The thermal shutdown temperature of the MAX77387EWP+T is 150°C. If the junction temperature exceeds this value, the IC will shut down to prevent damage. The IC will automatically restart when the temperature drops below 130°C.
