TL3845D-8 Frequently Asked Questions (FAQ)
-
The TL3845D-8 can operate from -40°C to 125°C, but the junction temperature should not exceed 150°C.
-
To ensure stable operation, make sure to follow the recommended PCB layout guidelines, use a suitable input capacitor, and provide a stable voltage supply. Also, ensure that the output voltage is within the specified range and the output current is within the maximum rating.
-
While the TL3845D-8 can be used in switch-mode power supplies, it is not recommended for high-current applications. The device is designed for low-power applications, and its maximum output current is limited to 1A. For high-current applications, consider using a more suitable device, such as the TL3844 or TL3846.
-
The output voltage of the TL3845D-8 can be calculated using the formula: Vout = (R1 / R2) * (Vref - Vfb), where R1 and R2 are the feedback resistors, Vref is the internal reference voltage (2.5V), and Vfb is the feedback voltage (typically 0.5V).
-
The EN (enable) pin is used to enable or disable the device. When the EN pin is high, the device is enabled, and when it is low, the device is disabled. This pin can be used to implement power-saving features or to shut down the device during fault conditions.
