Frequently Asked Questions
What is the maximum output current of the TPS54073PWPG4?
The TPS54073PWPG4 is rated for 14 A continuous output current, making it suitable for high-current point-of-load applications such as FPGA core power, DDR memory termination, and multi-core processor supply rails in server and networking equipment.
What input voltage range does the TPS54073PWPG4 support?
The TPS54073PWPG4 operates from an input voltage range of 2.2 V to 4 V, with a nominal input of 3.3 V. This narrow range is specifically optimized for point-of-load designs powered directly from a regulated 3.3 V intermediate bus, commonly found in high-density computing and networking platforms.
What control mode does the TPS54073PWPG4 use?
The TPS54073PWPG4 uses voltage-mode pulse width modulation (PWM) control. Voltage-mode control offers a straightforward single feedback loop, simplifying compensation network design while providing stable regulation across a wide range of output voltages and load conditions.
What package does the TPS54073PWPG4 use?
The TPS54073PWPG4 is housed in a 28-pin HTSSOP (Thermally Enhanced TSSOP) package with an exposed pad on the bottom. The exposed thermal pad conducts heat directly to the PCB ground plane, enabling the device to handle its 14 A rated current without excessive junction temperature rise.
Is the TPS54073PWPG4 output voltage adjustable?
Yes, the TPS54073PWPG4 features an adjustable output voltage set by an external resistor divider connected to the feedback pin. This allows designers to configure the output voltage to suit specific load requirements such as 1.0 V, 1.2 V, 1.5 V, or 1.8 V core supply rails for processors and FPGAs.
