TPS54824RNVR Buck Switching Regulator IC Positive Adjustable 0.6V 1 Output 8A 18-VFQFN
The TPS54824RNVR is a high‑density, 8‑ampere synchronous step‑down DC‑DC buck converter from Texas Instruments SWIFT™ product family. This fully‑integrated power regulator embeds high‑side and low‑side power MOSFETs, accepts a wide 4.5 V‑17 V input supply, and delivers adjustable output voltage ranging from 0.6 V to 12 V with ±0.85% high‑precision 0.6 V reference over full temperature range. Built on peak‑current‑mode control architecture, it supports adjustable 200 kHz‑1.6 MHz switching frequency plus external clock synchronization, comprehensive fault protection circuits and a dedicated power‑good monitoring signal. Optimized for space‑constrained, high‑current industrial and telecom power rails, the IC maintains reliable operation across junction temperatures of ‑40 °C to +150 °C while achieving excellent power‑conversion efficiency and fast transient load response.
The TPS54824RNVR serves as a versatile high‑current step‑down power solution for numerous industrial and embedded electronic systems, including telecom equipment power rails, FPGA and ASIC core power supplies, industrial automation control modules, high‑speed data acquisition hardware, server auxiliary power circuits, test‑and‑measurement instruments, portable high‑power computing devices, 12 V distributed bus power systems and multi‑voltage embedded processor boards requiring fast load‑transient performance.
FAQ
Q: Can multiple TPS54824RNVR devices run with synchronized switching frequency?
A: Yes, the RT/CLK pin accepts an external clock signal to synchronize converters and beat‑frequency noise.
Q: Is pre‑biased output startup supported?
A: This device features safe pre‑bias startup, preventing output‑voltage dip when powering up circuits with residual charge.
