The XH2576-3.3 is a monolithic step-down (buck) switching regulator from Xinluda Information Technology Co., Ltd. It integrates all of the active functions required for a fixed 3.3V output DC-DC converter capable of driving up to 3A of load current with excellent line and load regulation. As part of the XH2576 family — a function-compatible alternative to the industry-standard LM2576 — it requires only a minimal number of external components and a standard inductor, making it a compact, high-efficiency replacement for traditional three-terminal linear regulators.
With an internal fixed-frequency oscillator running at 52kHz, on-chip frequency compensation, cycle-by-cycle current limiting, and thermal shutdown, the XH2576-3.3 delivers reliable point-of-load power conversion across a wide input range while keeping the bill of materials and heatsink requirements low.
The XH2576-3.3 can be difficult to source through authorized Western distribution channels, which makes consistent supply a challenge for production and maintenance teams. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and optocouplers. We help engineers and buyers secure difficult-to-locate components like the XH2576-3.3 with a focus on authenticity, quality verification, and reliable global shipping.
Whether you need a single reel or volume quantities, our team can source this device and offer alternatives where appropriate. Request a quote (RFQ) today and let Pacific Component Xchange handle the hard-to-find sourcing so your build stays on schedule.
The XH2576-3.3 is a monolithic step-down (buck) switching DC-DC converter from Xinluda. It provides a fixed 3.3V output at up to 3A of load current in a TO-263-5 package.
The XH2576-3.3 operates over a wide input voltage range of 6V to 40V, making it suitable for a variety of step-down power-supply applications.
It uses an internal fixed-frequency oscillator running at 52kHz, which allows the use of readily available standard inductors and a minimal external component count.
The XH2576 family is widely used as a function-compatible alternative to the industry-standard LM2576-3.3 52kHz simple buck regulator. Always confirm pinout and electrical compatibility against the official datasheet for your specific design.
The device includes cycle-by-cycle current limiting and thermal shutdown to provide protection under fault conditions, along with internal frequency compensation.
The XH2576-3.3 can be difficult to source through authorized Western distribution channels. Pacific Component Xchange specializes in sourcing hard-to-find power-management ICs and can supply this part on request. Submit an RFQ for current availability and pricing.
