TPS2015DR datasheet by Texas Instruments

TPS2015DR Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the TPS2015DR?
  The TPS2015DR can operate from -40°C to 125°C, but the junction temperature should not exceed 150°C.
• How do I ensure the TPS2015DR is properly powered up and down?
  The TPS2015DR has an internal power-on reset (POR) circuit that ensures the device is properly powered up and down. However, it's recommended to follow a power-up sequence where the input voltage (VIN) is applied before the enable (EN) pin is asserted, and the EN pin should be de-asserted before VIN is removed.
• What is the recommended layout and placement for the TPS2015DR?
  To minimize noise and ensure proper operation, it's recommended to place the TPS2015DR close to the power source, use a solid ground plane, and keep the input and output traces short and wide. Additionally, decoupling capacitors should be placed close to the VIN and VOUT pins.
• How do I calculate the output voltage of the TPS2015DR?
  The output voltage of the TPS2015DR can be calculated using the formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors connected to the FB pin, VIN is the input voltage, and VREF is the internal reference voltage (1.22V).
• What is the maximum output current capability of the TPS2015DR?
  The TPS2015DR can deliver up to 1.5A of output current, but the maximum current is dependent on the input voltage, output voltage, and ambient temperature. It's recommended to check the device's thermal performance and power dissipation to ensure reliable operation.
