Texas Instruments DC-DC Buck Controller, 5-Channel, 8-Pin SOIC, 4.5 - 52V, 500kHz, Surface Mount TPS40200D

The Texas Instruments TPS40200D is a high-performance DC-DC buck controller specifically engineered for efficient step-down voltage regulation in a variety of electronic systems. Designed for use with external power MOSFETs, it offers exceptional design flexibility for board-level power supplies.

This controller operates from a wide input voltage range of 4.5V to 52V and supports up to 8 output channels, making it suitable for complex power architectures in both industrial and commercial electronics. Its compact 8-pin SOIC surface-mount package enables streamlined PCB layout and minimizes component footprint.

With a high switching frequency of 500kHz, the TPS40200D allows the use of smaller external components while maintaining high conversion efficiency. The maximum duty cycle of 95 percent supports a broad range of input and output voltages, and its robust voltage control loop ensures stable output under varying load conditions.

Reliable operation is ensured over a temperature range from minus 40°C to 85°C, making this controller suitable for environments subject to wide thermal variation. The TPS40200D meets the RoHS standard, providing a lead-free and environmentally conscious solution for modern power management requirements.

Industries such as telecommunications, industrial automation, consumer electronics, and embedded systems benefit from its high efficiency, robust performance, and flexible power management capabilities.
