XL3525Z – PWM Controller – Xinluda

The XL3525Z from Xinluda is a regulating pulse-width-modulation (PWM) controller in a SOP-16 package, functionally aligned with the industry-standard SG3525 for switch-mode power supply designs. Available for RFQ from Pacific Component Xchange.

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.
