The XL2594-12 is a member of Xinluda’s XL2594xx SIMPLE SWITCHER family of monolithic step-down (buck) switching voltage regulators. It integrates all of the active functions needed for a buck regulator capable of driving a 0.5-A load with excellent line and load regulation. The “-12” suffix denotes the factory-fixed 12 V output version; the same family is also offered in 3.3 V, 5 V, and adjustable (ADJ) variants. With an internal 150-kHz fixed-frequency oscillator and internal frequency compensation, the XL2594-12 requires only four external components, making it a simple, space-efficient choice for fixed 12 V rails.
The XL2594-12 is a Xinluda-branded part with little to no authorized-distributor stock in Western markets, which makes it difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs like the XL2594-12, giving design and procurement teams a reliable path to secure quantities when standard distributors come up empty. Every order is backed by our authenticity and quality-assurance process, and we ship globally to support both prototype and production needs. Request a quote (RFQ) for the XL2594-12 today and our sourcing specialists will respond with availability, lead time, and pricing.
The XL2594-12 is a Xinluda monolithic step-down (buck) switching voltage regulator. It provides a fixed 12 V output at up to 0.5 A from an input of up to 40 V, using a 150-kHz internal oscillator and only four external components, in an SOP-8 package.
The XL2594-12 delivers a factory-fixed 12 V output and is ensured for up to 0.5 A of output current.
The recommended operating supply voltage is 4.5 V to 40 V, with an absolute maximum supply rating of 45 V. For the 12 V output version, the datasheet specifies the output voltage over 15 V u2264 VIN u2264 40 V, so the input should be sufficiently above 12 V (15 V or higher) for proper regulation.
The XL2594-12 is supplied in an 8-pin SOP-8 surface-mount package.
It includes a two-stage frequency-reducing current-limit on the output switch and an overtemperature (thermal) shutdown for protection under fault conditions, plus a TTL-compatible ON/OFF shutdown input with an ~85 uA low-power standby mode.
Yes. The XL2594-12 has little to no authorized-distributor availability in Western markets. Pacific Component Xchange specializes in sourcing hard-to-find power-management ICs like this one. Submit an RFQ and our team will provide availability, lead time, and pricing.
