TPS53124RGER Frequently Asked Questions (FAQs)
TI provides a recommended PCB layout in the datasheet (Figure 23) and in the TPS53124RGER Evaluation Module User's Guide (SLUU444). Follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
The input capacitor values depend on the input voltage, output voltage, and desired ripple current. TI recommends using X7R or X5R ceramic capacitors with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the input voltage. Refer to the datasheet (Section 8.2.2) for more information.
The TPS53124RGER can deliver up to 2A of output current. However, the maximum output current is dependent on the input voltage, output voltage, and thermal conditions. Refer to the datasheet (Section 6.3) for more information on output current capability.
The TPS53124RGER has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the current limit threshold. For SCP, connect the SCP pin to a resistor divider network that sets the short-circuit detection threshold. Refer to the datasheet (Section 8.3.3) for more information.
The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing, shutdown, or low-power modes. Refer to the datasheet (Section 8.3.1) for more information.
