XD2525 – PWM Controller – Xinluda

The Xinluda XD2525 is a regulating pulse-width-modulator (PWM) controller in a DIP-16 package, operating from an 8-35V supply with switching frequencies up to 500kHz. It belongs to the industry-standard SG2525/SG3525 PWM controller family.

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.
