Description

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 components, such as transformers and filters. However, switching losses have been an obstacle to high-frequency 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 commutated, which dramatically reduces the switching losses and noise. FSFA2100 is an integrated PWM controller and SuperFET® specifically designed for Zero-Voltage-Switching (ZVS) half-bridge converters with minimal external components. The internal controller includes an oscillator, under-voltage-lockout, leading-edge blanking (LEB), optimized high-side and low-side gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation and self-protection circuitry. Compared with discrete MOSFET and PWM controller solution, FSFA2100 can reduce total cost; component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability.
