The Xinluda XL494 is a single-chip pulse-width-modulation (PWM) control IC designed for switch-mode power supply (SMPS) applications. Built on the widely adopted TL494 architecture, the XL494 integrates all the building blocks required for a complete PWM control loop, including two error amplifiers, an on-chip adjustable oscillator, a dead-time control comparator, a 5V reference, and two output transistors for push-pull or single-ended operation. Supplied in a compact SOP-16 surface-mount package, it is a cost-effective controller for power-conversion designs that follow the established 494-type pinout.
The XL494 is a Xinluda-branded part with limited authorized-distributor coverage in North America and Europe, which makes it difficult to procure through mainstream channels. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs and optocouplers, helping engineers and buyers secure parts like the XL494 even when standard catalog distributors show no stock.
Every order is backed by our authenticity and quality-assurance process to protect your build against counterfeit and substandard components, and we ship globally to support both prototype and production volumes. Because the XL494 is offered on a request-for-quote (RFQ) basis, our sourcing team can confirm current availability, lead time, packaging, and pricing tailored to your quantity. Request a quote from Pacific Component Xchange today and let our team handle the hard-to-find sourcing for you.
The XL494 is a fixed-frequency PWM control IC from Xinluda used in switch-mode power supplies. It integrates dual error amplifiers, an adjustable oscillator, a 5V reference, dead-time control, and two output transistors, all in an SOP-16 package.
The XL494 is built on the industry-standard TL494 architecture and shares the same functional blocks and 494-type pinout. As always, verify electrical parameters and timing against your specific design before substituting; our team can help cross-reference your requirements.
The XL494 referenced here is supplied in a 16-pin SOP-16 surface-mount package. Other 494-family packages such as DIP-16 exist in the broader Xinluda lineup; contact us to confirm the exact package for your order.
The XL494 operates over a supply voltage range of approximately 7V to 40V, with a typical quiescent current of about 6mA, making it suitable for a wide range of AC-DC and DC-DC power-supply designs.
Its on-chip oscillator is adjustable via external timing components and supports a switching frequency range of roughly 1kHz to 200kHz, set by the external R and C values you choose for your design.
Because the XL494 is an RFQ product, submit a quote request to Pacific Component Xchange with your quantity and target date. Our sourcing team will confirm current availability, lead time, packaging, and pricing.
