The Xinluda XH2596-3.3 is a monolithic integrated circuit that provides all of the active functions required for a step-down (buck) switching regulator. It delivers a fixed 3.3V output and is capable of driving a 3A load with excellent line and load regulation. Operating from a wide 4.5V to 40V input range with a 150kHz fixed-frequency internal oscillator, the XH2596-3.3 minimizes external component count and allows the use of smaller filter components than lower-frequency regulators. The device is a pin-compatible alternative within the popular 2596 step-down regulator family and is supplied here in the surface-mount TO-263-5 package.
The XH2596-3.3 is an independent-distribution part with little to no authorized-distributor stock, which can make it difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and end-of-life power-management ICs, helping engineers and buyers secure the parts their builds depend on. We focus on authenticity, supply-chain traceability, and responsive service, with global shipping to keep your production on schedule. Whether you need a single reel or volume quantities, request a quote (RFQ) from Pacific Component Xchange today and our sourcing team will respond quickly with availability and pricing for the XH2596-3.3.
It is a monolithic step-down (buck) switching regulator IC that provides a fixed 3.3V output at up to 3A of load current from a 4.5V to 40V input, operating at a 150kHz fixed switching frequency in a TO-263-5 package.
The device accepts a wide 4.5V to 40V input range and can drive a load of up to 3A while regulating a fixed 3.3V output.
This part is offered in the surface-mount TO-263-5 package.
The XH2596 belongs to the widely used 2596 family of step-down regulators sharing the same 3A, 150kHz fixed-frequency architecture, making it a functional alternative in many 2596-based designs. Always confirm pinout and electrical parameters against the datasheet for your specific application.
The regulator integrates switch current limiting (via two-stage frequency reduction) and thermal shutdown protection, plus an external shutdown function with a typical standby current of 80u00b5A.
Yes. The XH2596-3.3 is available through Pacific Component Xchange as a request-for-quote (RFQ) item. Submit an RFQ and our sourcing team will respond promptly with availability and pricing.
