The PQ3230 150W High-Frequency SMPS Transformer is a robust and efficient power transformer designed for switch-mode power supply applications requiring a 21V high-current output. Built on a PQ3230 MnZn ferrite core, this transformer is optimized for high-frequency operation and is fully compatible with OB2269CP-based SMPS designs. With a power handling capacity of up to 150 watts and multiple auxiliary/bias windings, this transformer is ideal for use in power adapters, battery chargers, LED drivers, audio amplifiers, and industrial SMPS circuits. High-grade copper windings ensure low losses, stable performance, and reliable operation across a wide temperature and frequency range.
