The Xinluda XD3526 is a high-reliability voltage-mode pulse-width-modulation (PWM) switching regulator controller supplied in an 18-pin DIP package. It is offered as a cost-effective, functional equivalent to the industry-standard UC3526AN, making it a practical second-source option for legacy and current isolated switching power-supply designs. A companion SOP-18 variant is offered under the part number XL3526.
Built around a temperature-compensated reference and sawtooth oscillator, the XD3526 integrates dual low-impedance power drivers, programmable soft-start, undervoltage lockout, and digital current limiting, allowing it to drive a wide range of isolated and non-isolated converter topologies with minimal external circuitry.
The XD3526 is a specialized, hard-to-find part with little or no authorized-distributor availability. Pacific Component Xchange is an independent distributor focused on hard-to-find power-management ICs and optocouplers, helping engineers and buyers secure obsolete, allocated, and niche components when mainstream channels come up empty.
Every order is backed by our commitment to authenticity, with inspection and verification to protect against counterfeit and substandard parts. We ship globally and can support both prototype quantities and production volumes. Because the XD3526 is a Request-For-Quote item, contact Pacific Component Xchange for a current quote, lead time, and stock confirmation on the XD3526 and equivalent UC3526AN-family controllers.
The XD3526 is a voltage-mode PWM switching regulator controller from Xinluda, supplied in an 18-pin DIP package. It is designed as a functional equivalent to the UC3526AN for isolated and non-isolated switching power supplies.
Yes. Xinluda positions the XD3526 as a cost-effective functional equivalent to the UC3526AN, sharing the same DIP-18 pinout-class package and core PWM controller feature set.
The XD3526 is supplied in an 18-pin DIP (DIP-18) package. Xinluda also offers an SOP-18 surface-mount variant under the part number XL3526.
The XD3526 operates from a 7 V to 35 V VCC supply and supports oscillator/switching frequencies up to 600 kHz, with a maximum duty cycle of 50% and a 7 V undervoltage-lockout threshold.
The XD3526 supports Boost, Buck, Flyback, Forward, Full-Bridge, Half-Bridge, and Push-Pull topologies, with dual 0.2 A outputs for driving switching power stages.
The XD3526 is a Request-For-Quote item with limited authorized-distributor availability. Contact Pacific Component Xchange for a current quote, lead time, and stock confirmation; we specialize in hard-to-find power-management ICs and ship globally.
