TPS54394PWPR Dual Synchronous Step-Down Switcher (Buck Converter)
The TPS54394PWPR is a high-efficiency, dual-channel synchronous step-down (buck) converter from Texas Instruments, integrating two N-channel MOSFETs per channel and housed in a compact 16-HTSSOP package with an exposed pad for enhanced thermal performance. Designed for industrial and embedded power supply applications, it supports an input voltage range of 4.5V to 18V and delivers up to 3A continuous current per channel with adjustable output voltages from 0.76V to 7V. Operating at a fixed 700kHz switching frequency with D-CAP2™ control mode, it ensures fast transient response and reduces external component count, while the Eco-Mode™ feature optimizes light-load efficiency for battery-powered systems. With a wide industrial temperature range of -40°C to +85°C and robust protection features, it serves as a cost-effective, compact power solution for multi-rail applications.
It integrates dual 3A synchronous buck regulators with on-chip high-side and low-side MOSFETs, eliminating the need for external power switches and simplifying PCB design. The device accepts 4.5V–18V input and provides 0.76V–7V adjustable outputs, with a fixed 700kHz switching frequency that balances efficiency and component size. D-CAP2™ control mode delivers ultra-fast transient response and tight regulation, while Eco-Mode™ enables pulse-skipping operation at light loads to improve efficiency and reduce power consumption. It includes cycle-by-cycle over-current protection, thermal shutdown, under-voltage lockout (UVLO), and power-good (PG) indicators for each channel, ensuring reliable operation under fault conditions.
