TPS54202DDCR

The TPS54202DDCR is a high-efficiency, EMI-friendly synchronous step-down converter designed for a wide input voltage range of 4.5V to 28V, with an output current capability of 2A. Manufactured by Texas Instruments, this converter integrates two switching FETs, internal loop compensation, and a 5ms internal soft-start feature, which helps to reduce component count and simplify circuit design.

The TPS54202DDCR operates at a switching frequency of 500kHz and offers an adjustable output voltage, making it suitable for a variety of power conversion applications. Its advanced eco-mode implementation maximizes light-load efficiency and minimizes power loss, making it an ideal choice for energy-conscious designs.

The converter employs a frequency spread spectrum operation to reduce EMI emissions, ensuring clean and reliable power delivery to sensitive loads. It also includes cycle-by-cycle current limiting in both the high-side and low-side MOSFETs, providing robust protection against overload and short-circuit conditions. If an overcurrent condition persists, the converter enters hiccup mode protection to prevent damage.

The TPS54202DDCR is packaged in a compact, surface-mount format, making it easy to integrate into modern electronic systems. Its high power density and small footprint on the PCB make it an excellent choice for space-constrained applications. Suitable for use in distributed power buses, home appliances, set-top boxes, digital TVs, printers, and other electronic devices, the TPS54202DDCR offers a combination of performance, reliability, and ease of use that makes it a valuable addition to any power conversion design.
