TL3845DR-8 Frequently Asked Questions (FAQ)
-
The TL3845DR-8 can operate from -40°C to 125°C, but the recommended operating temperature range is -20°C to 85°C for optimal performance.
-
To ensure stability, make sure to follow the recommended layout and component selection guidelines, and add a compensation capacitor (Cc) between pins 5 and 4. The value of Cc depends on the output voltage and load current.
-
The TL3845DR-8 can deliver up to 1.5A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions.
-
Yes, the TL3845DR-8 can be used as a high-voltage regulator, but it's essential to ensure the input voltage does not exceed the maximum rating of 40V. Additionally, proper heat sinking and thermal management are crucial to prevent overheating.
-
The output voltage of the TL3845DR-8 can be adjusted by using a resistive divider network between the output and the adjust pin (pin 5). The ratio of the resistors determines the output voltage.
