Instructions for TPS23861PWR

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 7V to 60V to avoid damage or improper operation.

2. Output Current Limit (IOUT):

   • The device can handle up to a maximum continuous output current of 2A. For optimal performance, keep the output current around the typical value of 1.2A.

3. Reverse Current Protection (IRVRS):

   • The device can block reverse currents up to 0.5mA. This helps protect against reverse polarity connections.

4. Quiescent Current (IQ):

   • The quiescent current should be monitored to ensure it stays within the 30μA to 50μA range under normal operating conditions.

5. Turn-On and Turn-Off Times (tON, tOFF):

   • Transition times from input to output and vice versa are critical for transient response. Typical values are 1.5μs for turn-on and 0.8μs for turn-off.

6. Thermal Shutdown (TSD):

   • If the junction temperature exceeds 160°C, the thermal shutdown activates to protect the device. Ensure adequate heat dissipation in your design.

7. Operating Junction Temperature (TJ):

   • The device is designed to operate within a temperature range of -40°C to 125°C. Exceeding these limits can affect reliability and lifespan.
