The Xinluda XD3525 is a monolithic regulating pulse-width-modulation (PWM) controller designed for switch-mode power-supply applications. It belongs to the well-established SG3525 / SG3525A family and is offered as a cost-effective, pin-compatible alternative to parts such as the SG3525AN, KA3525A and UC2525A. Housed in a 16-pin dual-in-line (DIP-16) package, the XD3525 combines the control circuitry required to build a complete push-pull, half-bridge or full-bridge converter onto a single chip.
The device integrates an on-chip oscillator, a high-gain error amplifier, internal soft-start, under-voltage lockout, and two alternating totem-pole outputs capable of sourcing and sinking 500mA each. The complementary outputs are well suited to driving power MOSFETs or bipolar transistors directly in transformer-coupled topologies.
The Xinluda XD3525 is an Asian-brand part with limited authorized-distributor coverage, which can make it difficult to source reliably for production runs and repairs. Pacific Component Xchange specializes in hard-to-find and end-of-life power-management ICs, helping engineers and procurement teams secure parts that mainline catalog distributors no longer stock. Every order is backed by our authenticity and quality-assurance program to guard against counterfeit and re-marked components, and we ship globally to meet your build schedule.
Because the XD3525 is offered on a request-for-quote (RFQ) basis, pricing and lead time are quoted per order against current availability. Submit an RFQ to Pacific Component Xchange today for the XD3525 and let our sourcing specialists confirm stock, pricing, and delivery for your quantity.
The XD3525 is a regulating pulse-width-modulation (PWM) controller from Xinluda. It belongs to the SG3525 family and is used as the control IC in switch-mode power supplies, integrating an oscillator, error amplifier, soft-start, under-voltage lockout, and dual 500mA totem-pole outputs in a DIP-16 package.
The XD3525 is offered as a pin-compatible, cost-effective alternative to the SG3525AN, KA3525A and UC2525A. It shares the same 16-pin DIP pinout and core functionality, making it suitable as a drop-in replacement in most SG3525-based designs. Always confirm electrical parameters against your specific application.
The XD3525 is supplied in a 16-pin dual-in-line (DIP-16) through-hole package and is RoHS compliant.
The XD3525 operates from an 8V to 35V supply, provides two alternating totem-pole outputs rated at 500mA each, supports switching frequencies from 100Hz up to 400kHz, and operates over a -40u00b0C to +85u00b0C temperature range with up to 1000mW power dissipation.
The XD3525 is an Asian-brand part with limited authorized-distributor availability, so it is offered on an RFQ basis. Pacific Component Xchange quotes pricing and lead time per order based on current stock. Submit an RFQ to get a confirmed quote for your quantity.
Yes. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs and can source the XD3525 in both prototype and production volumes, with authenticity verification and global shipping. Contact us with your quantity and target date for a quote.
