ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently.
Use a low-pass filter or a ferrite bead in series with the input signal to reduce high-frequency noise and ensure stable operation.
The maximum allowed voltage on the enable pin (EN) is VCC + 0.3V, but it's recommended to keep it within VCC to ensure proper operation.
While the TFZVTR9.1B is rated for operation up to 125°C, it's recommended to derate the output current and voltage to ensure reliable operation in high-temperature environments.
Check the input voltage, output voltage, and enable pin voltage with an oscilloscope to identify any anomalies. Also, verify the PCB layout and component placement to ensure proper operation.
