TPS54331DR
Brand: Texas Instruments
The TPS54331DR is an Eco-mode non-synchronous buck converter rated to a full -40°C to +150°C, exceeding most competing SOIC-8 buck converters for high-ambient industrial enclosures. A fixed 570 kHz switching frequency, 1 µA typical shutdown current and adjustable output down to 0.8 V from a 3.5 V to 28 V input round out a flexible point-of-load solution.

Power Features & Applications
- -40°C to +150°C rating exceeds most competing SOIC-8 buck converters for high-ambient industrial use
- Eco-mode pulse-skip control improves light-load efficiency versus fixed-PWM-only designs
- 1 µA typical shutdown current minimizes power draw when the rail is disabled
- Fixed 570 kHz switching frequency simplifies filter and magnetics design
- 3.5 V to 28 V wide input range covers common industrial and automotive-adjacent bus voltages
- 8-pin SOIC package and adjustable output down to 0.8 V fit most point-of-load rail voltages
