The recommended PCB layout for the MAX4373HESA+T involves keeping the input and output traces as short as possible, using a solid ground plane, and placing the device close to the power source. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane to minimize noise and EMI.
To ensure proper thermal management, it's recommended to provide a thermal pad on the PCB under the device, and to use a heat sink or thermal interface material (TIM) to dissipate heat. The device's thermal pad should be connected to a solid ground plane to help dissipate heat.
The MAX4373HESA+T has an operating temperature range of -40°C to +125°C, making it suitable for use in a wide range of applications, including automotive and industrial systems.
The MAX4373HESA+T's output voltage can be programmed using an external resistor divider network connected to the FB pin. The output voltage can be set to any value between 0.8V and 5.5V using this method.
The MAX4373HESA+T can handle input voltages up to 6.5V, making it suitable for use in applications where the input voltage may be higher than the output voltage.
