The Xinluda XH2576-12 is a monolithic step-down (buck) switching regulator that delivers a fixed 12V output at up to 3A of load current with good line and load regulation. Part of the XH2576 series, it provides a high-efficiency alternative to popular three-terminal linear regulators, substantially reducing heat-sink size and, in many designs, eliminating the heat sink entirely. The XH2576-12 belongs to an LM2576-12-compatible family, making it a convenient option for common buck-regulator designs.
Requiring a minimum of external components, the device integrates internal frequency compensation and a fixed-frequency oscillator, simplifying board design and reducing bill-of-materials cost. Built-in protection features keep the regulator robust under fault conditions.
The XH2576-12 is a hard-to-find part with little to no authorized-distributor stock. Pacific Component Xchange specializes in sourcing scarce, obsolete, and end-of-life power-management ICs and optocouplers for engineers and buyers who can’t get them through mainline channels. We focus on authenticity, careful inspection, and reliable global shipping so you receive the parts your build depends on.
Pricing for the XH2576-12 is quote-based. Submit an RFQ to Pacific Component Xchange and our sourcing team will confirm availability, lead time, and a firm quote for your required quantity.
The XH2576-12 is a Xinluda fixed 12V, 3A step-down (buck) switching regulator in a TO-263-5 package. It integrates the active functions of a buck regulator with internal frequency compensation and a 52 kHz fixed-frequency oscillator.
The XH2576 series is a high-efficiency, LM2576-compatible step-down regulator family, and the XH2576-12 is the fixed 12V version. For drop-in use in an existing LM2576-12 design, confirm pin assignment and electrical parameters against the datasheet for your application.
It provides a fixed 12V output at a specified 3A output current, with u00b14% output voltage tolerance under the specified line and load conditions.
It includes cycle-by-cycle current limiting, thermal shutdown, and an external shutdown input with a low-power standby mode drawing 50 u00b5A typical.
The XH2576-12 is supplied in a surface-mount TO-263-5 package, suitable for designs that need a buck regulator with good thermal dissipation.
The XH2576-12 has limited authorized-distributor availability and is offered on an RFQ basis. Submit a quote request to Pacific Component Xchange and our team will confirm stock, lead time, and pricing for your quantity.
