FSFA2100 Overview
The growing demand for higher power density and low profile in power converter designs has forced designers to increase switching frequencies. Operation at higher frequencies considerably reduces the size of passive ponents, such as transformers and filters. However, switching losses have been an obstacle to highfrequency operation. To reduce switching losses and allow high-frequency operation, Pulse Width Modulation (PWM) with soft-switching techniques have been developed. These techniques allow switching devices to be softly mutated, which dramatically reduces the switching losses and noise. FSFA2100 is an integrated PWM controller and SuperFET™ specifically designed for Zero-VoltageSwitching (ZVS) half-bridge converters with minimal external ponents. The internal controller includes an oscillator, under-voltage-lockout, leading-edge blanking (LEB), optimized high-side and low-side...
