The XL3525Z is a regulating pulse-width-modulation (PWM) controller manufactured by Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.). It belongs to Xinluda’s 3525-series of switching controllers and is functionally aligned with the widely deployed industry-standard SG3525 architecture, making it a practical building block for switch-mode power supplies (SMPS), DC-DC converters, and inverter designs. The “Z” suffix denotes the SOP-16 (SOP-16Z) surface-mount package; a pin-compatible DIP-16 variant is offered as the Xinluda XD3525.
This device integrates the core control functions required for a complete PWM power-supply controller, including an on-chip voltage reference, error amplifier, oscillator with programmable dead-time, soft-start circuitry, under-voltage lockout, and a totem-pole output stage that can both source and sink current to drive external power switches directly.
The XL3525Z is a specialized Xinluda part with little to no authorized-distributor stock outside of Asia, which can stall production when a build calls for this exact device. Pacific Component Xchange specializes in sourcing hard-to-find and allocated power-management ICs like the XL3525Z. We support engineers and procurement teams who need a scarce or single-source component matched to their bill of materials.
Every order is backed by our commitment to authenticity and quality, with inspection and traceability processes to help protect against counterfeit and non-conforming parts. We ship globally and respond quickly to quote requests with current availability and lead time. Request a quote (RFQ) for the XL3525Z today and our sourcing team will get back to you with pricing and availability.
The XL3525Z is a regulating pulse-width-modulation (PWM) controller IC from Xinluda, supplied in a SOP-16 (SOP-16Z) package. It is functionally aligned with the industry-standard SG3525 and is used to control switch-mode power supplies and DC-DC converters.
The XL3525Z follows the SG3525 regulating-PWM-modulator architecture and shares the same core feature set (8-35 V supply, totem-pole outputs, soft-start, under-voltage protection). Always confirm pinout and parametric compatibility against the Xinluda datasheet for your specific design before substituting.
The XL3525Z is the SOP-16 (SOP-16Z) surface-mount variant of Xinluda's 3525 series. A pin-compatible DIP-16 variant is offered as the Xinluda XD3525.
Per the manufacturer data, it operates from an 8 V to 35 V supply, supports a switching frequency from 100 Hz to 400 kHz, provides totem-pole outputs rated up to 500 mA, and offers a maximum duty cycle of about 49% with built-in soft-start and under-voltage protection.
The XL3525Z has limited authorized-distributor availability outside Asia. Pacific Component Xchange specializes in sourcing scarce and hard-to-find power-management ICs. Submit an RFQ and our team will respond with current pricing, availability, and lead time.
Yes. Pacific Component Xchange ships globally and supports procurement teams worldwide with authenticity verification and traceability on hard-to-find components like the XL3525Z.
