XL3525K – PWM Controller – Xinluda

The XL3525K from Xinluda is a regulating pulse-width-modulation (PWM) controller in a SOP-16 package, based on the industry-standard SG3525 architecture for switch-mode power supplies. Available for quote through Pacific Component Xchange.

The XL3525K is a regulating pulse-width-modulation (PWM) controller manufactured by Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.). It belongs to the well-established SG3525 family of regulating PWM modulators and is supplied in a surface-mount SOP-16 package. The device integrates a precision voltage reference, an error amplifier, a programmable oscillator with dead-time control, soft-start, under-voltage lockout, and dual totem-pole outputs that simplify the design of push-pull, half-bridge, and full-bridge switch-mode power supplies.

Key Features

• Regulating pulse-width-modulation (PWM) controller, SG3525-family architecture
• SOP-16 surface-mount package (the “K” suffix denotes the SOP-16 option; the XL3525Z is another SOP-16 variant and the XD3525 is the DIP-16 version in the same family)
• Wide operating supply voltage range of 8 V to 40 V
• Programmable oscillator with dead-time control
• Dual complementary totem-pole outputs for driving push-pull and bridge power stages
• Approximately 45% maximum duty cycle per output
• Integrated soft-start and under-voltage lockout (UVLO)
• Operating temperature range of -40 C to +85 C

Applications

• Switch-mode power supplies (SMPS)
• DC-DC converters (push-pull, half-bridge, full-bridge)
• Off-line AC-DC converters and offline switchers
• Inverters and uninterruptible power supplies (UPS)
• Industrial and instrumentation power modules
• Motor-drive and lighting power stages

Why Source XL3525K from Pacific Component Xchange

The XL3525K is a regional/specialty part with little to no authorized-distributor stock, which makes it difficult to procure through mainstream channels. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs and optocouplers, helping engineers and buyers secure the exact PWM controller their design was built around without forcing a costly redesign or qualification cycle.

Every XL3525K we supply is sourced with authenticity and traceability in mind, backed by our inspection and quality processes, and we ship globally to meet production schedules. Pricing on this part is quote-based. Request a quote (RFQ) from Pacific Component Xchange today with your quantity and target date, and our sourcing team will confirm availability and lead time.
