MAX1745AUB+T Frequently Asked Questions (FAQ)
-
A good PCB layout for the MAX1745AUB+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. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
-
To ensure the stability of the output voltage, it's essential to choose the correct output capacitor value and type. A minimum capacitance of 10uF is recommended, and the capacitor should have a low ESR (Equivalent Series Resistance) to minimize voltage ripple. Additionally, the output voltage can be stabilized by adding a small ceramic capacitor (e.g., 100nF) in parallel with the output capacitor.
-
The MAX1745AUB+T can handle a maximum input voltage of 28V. However, it's recommended to operate the device within the specified input voltage range of 4.5V to 24V for optimal performance and reliability.
-
The output voltage of the MAX1745AUB+T can be calculated using the following formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage can be adjusted by changing the ratio of R1 and R2.
-
The EN (Enable) pin is used to enable or disable the MAX1745AUB+T. When the EN pin is pulled high (above 1.4V), the device is enabled, and when it's pulled low (below 0.4V), the device is disabled. The EN pin can be connected to a logic signal or a switch to control the power-on and power-off sequences.
