The Xinluda XD2525 is a monolithic regulating pulse-width-modulator (PWM) controller designed for switch-mode power supply applications. Part of the widely adopted SG2525/SG3525 controller family, it integrates the core building blocks needed for a voltage-mode PWM regulator in a single DIP-16 package, including an oscillator, error amplifier, soft-start and under-voltage lockout circuitry, and dual complementary totem-pole output drivers for directly driving power MOSFETs or transistors in push-pull, half-bridge, and full-bridge topologies.
With a wide 8V to 35V operating supply range and switching frequencies up to 500kHz, the XD2525 is well suited to DC-DC converters, inverters, and offline switching power supplies where precise duty-cycle control and reliable startup behavior are required.
The XD2525 is produced by Xinluda, an Asia-based semiconductor manufacturer with limited authorized-distributor coverage in Western markets, which can make this PWM controller difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs, helping engineers and procurement teams secure parts that are otherwise unavailable.
Every order is backed by our commitment to authenticity and quality verification, with global shipping to wherever your build or production line is located. Whether you need a prototype quantity or a production run, our team can help you locate verified stock and competitive pricing.

The XD2525 is a regulating pulse-width-modulator (PWM) controller from Xinluda, supplied in a DIP-16 package. It integrates an oscillator, error amplifier, soft-start, under-voltage lockout, and dual complementary totem-pole output drivers for switch-mode power supply control.
Yes. The XD2525 belongs to the industry-standard SG2525/SG3525 PWM controller family and shares the same DIP-16 functional architecture. As always, confirm pinout and electrical parameters against the datasheet for your specific design before substituting.
Per Xinluda's published data, the XD2525 operates from an 8V to 35V supply, switches at up to 500kHz, drives 500mA totem-pole outputs, and provides a maximum duty cycle of approximately 49% with integrated soft-start and under-voltage lockout.
The XD2525 is offered in a 16-pin DIP-16 through-hole package.
It is used to control DC-DC converters, switch-mode power supplies, push-pull and bridge converters, inverters, and other power-conversion stages that require regulated PWM switching.
Xinluda has limited authorized-distributor presence in Western markets, so the XD2525 is often unavailable through mainstream channels. Pacific Component Xchange specializes in hard-to-find power-management ICs and can source verified stock on an RFQ basis with global shipping.
