TPS61062DRBR datasheet by Texas Instruments

TPS61062DRBR Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value and type for the TPS61062DRBR?
  The recommended input capacitor value is 10uF to 22uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize input voltage ripple.
• How do I optimize the layout for the TPS61062DRBR to minimize EMI and noise?
  To minimize EMI and noise, it is recommended to follow a star-ground configuration, keep the input and output capacitors close to the device, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW pin) away from sensitive nodes.
• What is the maximum ambient temperature range for the TPS61062DRBR?
  The maximum ambient temperature range for the TPS61062DRBR is -40°C to 125°C. However, the device's performance and reliability may degrade at temperatures above 85°C, so it is recommended to keep the ambient temperature below 85°C for optimal operation.
• Can I use the TPS61062DRBR in a battery-powered device?
  Yes, the TPS61062DRBR is suitable for battery-powered devices due to its low quiescent current (IQ) of 12uA, which helps to extend battery life. However, it is essential to consider the device's power consumption and battery life requirements when designing the system.
• How do I calculate the output voltage of the TPS61062DRBR?
  The output voltage of the TPS61062DRBR can be calculated using the following formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.2V), R1 is the feedback resistor, and R2 is the divider resistor. The recommended values for R1 and R2 are 1kΩ and 2.2kΩ, respectively.
