TPS65581PWP Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the TPS65581PWP datasheet (Section 10.2) and in the TPS65581PWP Evaluation Module User's Guide (SLUU444). It's essential to follow these guidelines to minimize noise, ensure proper thermal dissipation, and optimize performance.
The input capacitor values depend on the input voltage, output voltage, and desired output ripple. TI recommends using X5R or X7R 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 7.3.1) for more information.
The TPS65581PWP can deliver up to 1.5A 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 TPS65581PWP has built-in OVP and UVP features. To implement these features, connect the OVP and UVP pins to the desired voltage threshold using resistive dividers. Refer to the datasheet (Section 7.3.4) for more information on OVP and UVP implementation.
The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device during shutdown or low-power modes.
