A recommended PCB layout for FMMT617TC is to use a ground plane on the bottom layer, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a 10nF capacitor between the input and ground pins to reduce noise and oscillations.
To ensure proper biasing, make sure to connect the enable pin (EN) to a logic high (VCC) to enable the device. Also, ensure that the input voltage (VIN) is within the recommended range of 2.7V to 5.5V, and that the output voltage (VOUT) is within the recommended range of 1.2V to 3.6V.
The maximum current rating of FMMT617TC is 1A. However, it's recommended to operate the device within the recommended operating current range of 0.1A to 0.5A to ensure optimal performance and reliability.
To protect the FMMT617TC from overvoltage and undervoltage conditions, it's recommended to use a voltage supervisor or a voltage monitor IC to detect and respond to voltage faults. Additionally, consider using a TVS diode or a zener diode to clamp the input voltage to a safe level.
The thermal resistance of FMMT617TC is 125°C/W. To ensure proper thermal management, make sure to provide adequate heat sinking, such as a copper plane or a heat sink, and ensure good airflow around the device. Additionally, consider using a thermal interface material to improve heat transfer between the device and the heat sink.
