The TPS53515RVER is a SWIFT synchronous step‑down buck converter from Texas Instruments, delivered in 28‑pin VQFN‑CLIP 3.5×4.5 mm tape‑and‑reel package, supporting 12 A continuous output current, 1.5‑18 V main input plus 4.5‑25 V bias supply, adjustable 0.6 V‑5.5 V output with D‑CAP3 control architecture, targeting high‑efficiency point‑of‑load power conversion for industrial and computing hardware.
Key Features & Applications
● Integrated high‑low side MOSFETs deliver 12 A continuous output current with low on‑state resistance for high conversion efficiency across load ranges.
● D‑CAP3 adaptive on‑time control provides ultra‑fast load transient response and eliminates external compensation components, simplifying PCB layout work.
● 0.6 V reference with ±0.5% accuracy, selectable switching frequency from 250 kHz to 1 MHz, and dual operation modes including Eco‑mode for light‑load efficiency and FCCM for low output ripple.
● Built‑in pre‑biased startup, output discharge circuit, open‑drain power‑good indicator, and comprehensive protection functions such as over‑voltage, under‑voltage, over‑current and thermal shutdown.
This DC‑DC regulator is widely deployed in FPGA and SoC core power supplies, server peripheral boards, industrial automation modules, high‑speed data acquisition equipment, networking hardware, embedded computing platforms and multi‑voltage point‑of‑load circuits requiring large output current and compact board space.
FAQ
Q: Why use separate PVIN and VDD bias inputs?
A: VDD bias maintains stable gate drive when PVIN drops low, preserving efficiency at low main input voltage.
Q: Are external compensation capacitors required?
A: No, D‑CAP3 control removes compensation network needs.
Q: What precautions apply for high‑current layout?
A: Keep power loop traces short and leverage the exposed thermal pad for adequate heat dissipation.
