Frequently Asked Questions
What is the input and output voltage range of the TPS54673PWPG4?
The TPS54673PWPG4 accepts an input voltage from 3V to 6V with a nominal input of 5.5V. The output voltage is adjustable and can be set using external resistors to meet specific load requirements. This range suits USB power, 5V system rails, and single-cell lithium battery applications requiring step-down regulation.
What is the maximum output current of the TPS54673PWPG4?
The TPS54673PWPG4 can deliver up to 6A of continuous output current. The integrated high-side and low-side power MOSFETs and voltage-mode PWM control technique ensure high efficiency and tight regulation even at full load, reducing the need for external power devices and simplifying the overall design.
What package does the TPS54673PWPG4 use and what are its thermal characteristics?
The TPS54673PWPG4 is housed in a 28-pin HTSSOP (R-PDSO-G28) package with an exposed thermal pad on the bottom. The thermal pad significantly improves heat dissipation when soldered to a PCB ground plane, allowing the device to handle its full 6A output current rating without excessive junction temperature rise.
Is the TPS54673PWPG4 RoHS compliant?
Yes, the TPS54673PWPG4 carries the JESD-609 e4 code, indicating it is fully RoHS compliant and lead-free. Texas Instruments manufactures this part to meet international environmental regulations, making it suitable for consumer, industrial, and automotive applications that require compliance with EU RoHS directives.
What control method does the TPS54673PWPG4 use for voltage regulation?
The TPS54673PWPG4 uses voltage-mode pulse width modulation (PWM) control for regulation. Voltage-mode control simplifies compensation design and provides good noise immunity, ensuring stable operation across varying load conditions. The fixed-frequency PWM architecture also makes filtering easier compared to variable-frequency hysteretic controllers.
