TPS54260DGQ – TEXAS INSTRUMENTS

The TPS54260DGQ is a 40V, 2A synchronous step-down converter from Texas Instruments, packaged in a 20-pin QFN (Quad Flat No-Lead) package. This device utilizes a hysteretic control architecture for fast transient response and minimal output voltage ripple, making it ideal for applications requiring tight voltage regulation under dynamic loads. Its input voltage range spans 4.5V to 40V, allowing for flexible power supply designs. The TPS54260DGQ boasts a high efficiency exceeding 95% across a wide load range, minimizing power loss and improving thermal performance. Key features include programmable output voltage via external resistors, enabling customization to specific system requirements. It incorporates internal soft-start and overcurrent protection, enhancing system robustness. Common use cases include intermediate bus voltage conversion in distributed power architectures, powering high-performance microprocessors, and powering high-current loads from a higher voltage source. Its compact size and high efficiency make it a strong candidate for space-constrained, high-power-density applications where reliable and efficient voltage regulation is paramount. The device’s inherent protection mechanisms simplify design and reduce the need for external components, contributing to a smaller overall solution size.
