A good PCB layout for the MAX16025TE+T involves keeping the input and output traces short and wide, using a solid ground plane, and placing the input and output capacitors close to the device. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure proper power-up and initialization of the MAX16025TE+T, make sure to follow the recommended power-up sequence, which involves applying the input voltage (VIN) before the enable signal (EN). Also, ensure that the input voltage is within the recommended operating range and that the device is properly bypassed with capacitors.
The maximum output current capability of the MAX16025TE+T is 1.5A. However, it's recommended to derate the output current based on the ambient temperature and the desired output voltage to ensure reliable operation.
The output voltage of the MAX16025TE+T can be adjusted by 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 EN pin on the MAX16025TE+T is an active-high enable input that allows the device to be turned on and off. To use the EN pin, simply tie it to a logic high (VIN) to enable the device, or tie it to a logic low (GND) to disable the device.
