Frequently Asked Questions
What is the output current and voltage range of the TPS74401KTWR?
The TPS74401KTWR supports a maximum output current of 3.0A with an adjustable output voltage range. The input voltage can range from approximately 1.5V to 5.5V, making it suitable for a wide range of power supply designs in industrial and consumer electronics.
What does the programmable soft-start feature do in the TPS74401KTWR?
The programmable soft-start feature allows designers to control the ramp-up time of the output voltage during power-up. By selecting an external capacitor, the soft-start duration can be tuned to limit inrush current, protect downstream components, and ensure orderly power sequencing in multi-rail systems.
What package does the TPS74401KTWR use, and what are its thermal characteristics?
The TPS74401KTWR comes in a KTW thermally-enhanced package (TO-263-7 style), which provides a low thermal resistance path to the PCB. This allows the device to deliver its full 3.0A output current while maintaining junction temperatures within safe limits in compact board designs.
What are common applications for the TPS74401KTWR?
Common applications include FPGA and DSP core power supplies, point-of-load regulators in telecom equipment, industrial motor controllers, and embedded computing boards. Its high PSRR and adjustable output make it a versatile choice wherever a clean, stable voltage rail is needed.
Where can I buy the TPS74401KTWR and what is the typical price?
The TPS74401KTWR is available from authorized distributors and stocking partners worldwide. The typical unit price starts from approximately $6.24 depending on quantity and distributor. FindMyChip offers global sourcing and quick-quote services for this part.
