XH2596-12 – DC-DC Converter – Xinluda
The XH2596-12 from Xinluda is a fixed 12V output step-down (buck) switching regulator rated for 3A load current in a TO-263-5 surface-mount package. Available for RFQ from Pacific Component Xchange.
The XH2596-12 is a monolithic step-down (buck) switching voltage regulator from Xinluda, part of the XH2596 series. It integrates all the active functions required for a high-efficiency step-down switching regulator, delivering a fixed 12V output and capable of driving loads up to 3A with excellent line and load regulation. The device requires only a minimal number of external components, simplifying board design and reducing bill-of-material cost.
Built around a 150kHz fixed-frequency internal oscillator, the XH2596-12 allows the use of smaller, lower-cost filter components than lower-frequency switching regulators would require. Integrated protection features include cycle-by-cycle current limiting and thermal shutdown, making it a robust choice for industrial and consumer power-supply designs. The XH2596 series is offered in TO-220 and TO-263 packages; the XH2596-12 listed here is the surface-mount TO-263-5 (D2PAK) variant.
Key Features
- Fixed 12V output (XH2596-12 variant of the XH2596 3.3V / 5V / 12V / ADJ family)
- Up to 3A output load current
- Wide input voltage range of 4.5V to 40V
- 150kHz fixed-frequency internal oscillator
- +/-4% output voltage tolerance over line and load conditions
- +/-15% tolerance on oscillator frequency
- External shutdown capability with typical 80uA standby current
- Current limiting via two-stage frequency reduction and thermal shutdown protection
- Requires only four external components
- TO-263-5 surface-mount package
Applications
- Simple, high-efficiency step-down (buck) regulators
- On-board 12V point-of-load power conversion
- Industrial control and instrumentation power supplies
- Consumer electronics and appliance power rails
- Pre-regulators for linear regulators
- LM2596-compatible step-down regulator replacement designs
Why Source XH2596-12 from Pacific Component Xchange
The XH2596-12 is a hard-to-find part with little to no authorized-distributor stock, which can stall production for designs that depend on it. Pacific Component Xchange is an independent distributor specializing in scarce and obsolete power-management ICs and optocouplers. We help engineering and procurement teams secure difficult-to-source components like the XH2596-12 when traditional supply channels come up empty.
Every order is backed by our commitment to authenticity, quality inspection, and counterfeit-avoidance practices, with global shipping to keep your build on schedule. Because this is a Request-For-Quote item, pricing and lead time are confirmed per order based on current availability. Contact Pacific Component Xchange today to request a quote on the XH2596-12 and let our sourcing team track down the quantity you need.
