TPS3779ADBVR datasheet by Texas Instruments

TPS3779ADBVR Frequently Asked Questions (FAQs)

• What is the recommended layout for the TPS3779ADBVR to ensure optimal performance?
  The recommended layout for the TPS3779ADBVR involves placing the input capacitor (CIN) close to the VIN pin, and the output capacitor (COUT) close to the VOUT pin. Additionally, the device should be placed close to the power source, and the output voltage sense lines should be routed away from noisy signals.
• How do I choose the correct input and output capacitors for the TPS3779ADBVR?
  The input capacitor (CIN) should have a low ESR and be rated for the input voltage. A ceramic capacitor with a value of 1-10uF is recommended. The output capacitor (COUT) should have a low ESR and be rated for the output voltage. A ceramic capacitor with a value of 1-22uF is recommended. The capacitor values can be adjusted based on the specific application requirements.
• What is the maximum output current that the TPS3779ADBVR can deliver?
  The maximum output current of the TPS3779ADBVR is 1.5A. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
• How do I adjust the output voltage of the TPS3779ADBVR?
  The output voltage of the TPS3779ADBVR can be adjusted by connecting a resistive divider network between the VOUT pin and the GND pin. The resistive divider network should be designed to provide a voltage feedback signal to the FB pin that is proportional to the output voltage.
• What is the purpose of the EN pin on the TPS3779ADBVR?
  The EN (enable) pin is used to enable or disable the TPS3779ADBVR. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and the output voltage is turned off.
