Frequently Asked Questions
What DDR memory types does the TPS51116PWP support?
The TPS51116PWP supports a comprehensive range of DDR memory standards including DDR, DDR2, DDR3, DDR3L, LPDDR3, and DDR4, making it a versatile single-chip power solution for modern memory subsystems across laptops, desktops, and embedded platforms.
What is the input voltage range of the TPS51116PWP?
The TPS51116PWP accepts an input voltage range from 3V minimum to 28V maximum, with a nominal operating voltage of 5V. This wide range allows it to be used in a variety of power supply architectures including those powered from USB, battery, or system rails.
What control mode does the TPS51116PWP use?
The TPS51116PWP uses current-mode control combined with pulse width modulation (PWM). Current-mode control provides inherent cycle-by-cycle current limiting, improved transient response, and easier loop compensation compared to voltage-mode designs.
What package does the TPS51116PWP come in?
The TPS51116PWP is housed in a 20-pin SOIC (Small Outline Integrated Circuit) package, designated JESD-30 code R-PDSO-G20. This compact surface-mount package is lead-free (Pbfree: Yes) and suitable for high-density PCB designs.
Where can I buy the TPS51116PWP and what is the price?
The TPS51116PWP is available from global electronic component distributors starting from approximately $1.01 per unit. FindMyChip offers worldwide shipping and can source both standard quantities and bulk orders to meet your procurement needs.
