TPS2055ADR datasheet by Texas Instruments

TPS2055ADR Frequently Asked Questions (FAQs)

• What is the maximum current limit for the TPS2055ADR?
  The maximum current limit for the TPS2055ADR is 1.5A, but it can be adjusted using an external resistor (RSENSE) to a minimum of 100mA.
• How do I calculate the current limit for the TPS2055ADR?
  The current limit can be calculated using the formula: I_LIM = 0.5V / RSENSE, where RSENSE is the sense resistor value in ohms.
• What is the purpose of the EN pin on the TPS2055ADR?
  The EN (enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled and the output is turned off.
• Can I use the TPS2055ADR as a high-side switch?
  No, the TPS2055ADR is a low-side switch, meaning it can only switch the ground connection of a load. It cannot be used as a high-side switch to switch the positive voltage supply of a load.
• What is the minimum input voltage required for the TPS2055ADR?
  The minimum input voltage required for the TPS2055ADR is 2.7V, but it can operate down to 2.5V with reduced performance.
