    static, PWM


The valley switching converter shows lower EMI and higher power conversion efficiency compared to the hard switched converter with a fixed switching frequency. The FSQ-Series were specially made for the purpose of valley switching operation with minimal external components. Each high class PWM controller comes with an integrated fixed-frequency oscillator, Leading Edge Blanking (LEB), optimized gate driver and the well known internal soft-start. This very remarkable device also has a self-protection circuitry and Under-Voltage Lockout as an added value and convenience to the consumers. Compared to other controller solutions, the FSQ-Series is known for its cost-effective designs and world-class quality.
