TPS2113APW datasheet by Texas Instruments

TPS2113APW Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from each channel?
  The maximum current that can be drawn from each channel is 1.5A, but it's recommended to limit it to 1A for optimal performance and thermal considerations.
• How do I ensure proper thermal management for the TPS2113APW?
  Proper thermal management can be achieved by providing a heat sink, ensuring good airflow, and keeping the device away from heat sources. The thermal pad on the bottom of the package should be connected to a copper plane on the PCB to dissipate heat.
• What is the purpose of the ENx pins, and how do I use them?
  The ENx pins are enable inputs that allow the user to turn on or off each channel independently. A logic high on the ENx pin enables the corresponding channel, while a logic low disables it.
• How do I sequence the power-up and power-down of the channels?
  The TPS2113APW has a built-in power-up and power-down sequencing feature. The device powers up and powers down in a staggered manner to prevent large inrush currents. The power-up sequence is channel 1, channel 2, and then the output voltage regulators. The power-down sequence is the reverse of the power-up sequence.
• What is the recommended layout and routing for the TPS2113APW?
  The recommended layout and routing for the TPS2113APW involves keeping the input and output capacitors close to the device, using short and wide traces for the power lines, and avoiding vias under the device to minimize thermal resistance.
