Frequently Asked Questions
What input voltage range does TPS40055MPWPREPG4 support for step-down conversion?
The TPS40055 supports an input voltage range of 8 V to 40 V, with a nominal operating voltage of 24 V, making it suitable for industrial 12 V, 24 V, and 48 V bus power supplies requiring step-down regulation at up to 585 kHz switching frequency.
For which industrial applications is TPS40055MPWPREPG4 best suited given its 40 V tolerance?
Industrial motor drive controllers, telecom rectifiers, and 24 V bus power modules benefit most. The 40 V input tolerance handles automotive and industrial voltage transients, while the 585 kHz switching frequency and voltage-mode control keep the 16-pin HTSSOP EP design compact and thermally efficient.
How does the 16-pin HTSSOP EP package affect thermal performance of TPS40055MPWPREPG4?
The 16-pin HTSSOP EP package includes an exposed pad that significantly reduces thermal resistance to the PCB, allowing higher continuous output current operation. This allows designers to extract more power from the controller without external heatsinks, making it efficient for dense 24 V industrial power supply boards.
