XL2525K – PWM Controller – Xinluda

The Xinluda XL2525K is a regulating pulse-width-modulator (PWM) controller in an SOP-16 package, designed for switch-mode power supplies and following the industry-standard SG2525/SG3525 architecture. Available on a request-for-quote basis from Pacific Component Xchange.

The XL2525K from Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.) is a fixed-frequency regulating pulse-width-modulator (PWM) controller housed in an SOP-16 package. Belonging to the classic SG2525/SG3525-style architecture, the XL2525K integrates an error amplifier, oscillator, soft-start, and dual totem-pole outputs to drive a wide range of switch-mode power-supply topologies with a minimum of external components.

With a wide operating supply range and an oscillator that reaches up to 500 kHz, the XL2525K is well suited to push-pull, half-bridge, full-bridge, forward, flyback, boost, and buck converter designs. It is a cost-effective, widely-sourced alternative for designs originally built around legacy SG-series PWM controllers.

Key Features

• Regulating pulse-width-modulator (PWM) controller for switch-mode power supplies
• Wide operating voltage range: 8 V to 40 V
• Oscillator frequency up to 500 kHz
• Dual totem-pole outputs rated approximately 0.4 A
• Supports Boost, Buck, Flyback, Forward, Full-Bridge, Half-Bridge and Push-Pull topologies
• SG2525 / SG3525-compatible architecture
• SOP-16 surface-mount package

Applications

• Switch-mode power supplies (SMPS)
• DC-DC converters and isolated power modules
• Push-pull, half-bridge and full-bridge inverters
• Industrial power and motor-drive supplies
• Battery chargers and LED drivers
• Legacy SG2525/SG3525 design replacements

Why Source XL2525K from Pacific Component Xchange

The XL2525K is a hard-to-find part with little or no authorized-distributor stock, making it a challenge for buyers managing legacy or high-mix power designs. Pacific Component Xchange specializes in sourcing scarce and obsolete power-management ICs and optocouplers. Whether you need a small bridge quantity or a full production run, our team can help you locate authentic XL2525K devices, verify their provenance, and ship globally.

Pricing on the XL2525K is provided by quotation. Submit an RFQ to Pacific Component Xchange and our sourcing specialists will respond with current availability, lead time, and pricing. We support hard-to-find and end-of-life procurement, authenticity verification, and worldwide shipping.
