XH2596-5.0 – DC-DC Converter – Xinluda
The Xinluda XH2596-5.0 is a fixed 5V, 3A monolithic step-down (buck) switching regulator in a TO-263-5 surface-mount package, pin-compatible with the popular LM2596 family. Available for RFQ from Pacific Component Xchange.
The Xinluda XH2596-5.0 is a monolithic integrated step-down (buck) switching regulator that delivers a fixed 5.0V output at up to 3A of load current with excellent line and load regulation. Part of Xinluda’s XH2596 series, this device is functionally and pin-compatible with the industry-standard LM2596 family, making it a practical drop-in alternative for legacy 5V switching designs. It integrates all the active functions required for a step-down regulator, requiring only a minimal set of external components.
Operating from a wide input voltage range of 4.5V to 40V and running at a fixed 150 kHz switching frequency, the XH2596-5.0 allows the use of smaller, lower-cost filter components than lower-frequency regulators while maintaining a tight ±4% output voltage tolerance over the specified line and load conditions. Built-in protection and a TTL-level shutdown input make it well suited to rugged, cost-sensitive power conversion.
