FSL5x8A/H High Performance 800 V Off-Line Switcher with HV Startup and SenseFET

onsemi FSL5x8A/H PWM power switch provides a base platform for cost-effective design of isolated and non-isolated flyback converters

Image of onsemi FSL5x8A/H: High Performance 800 V Off-line Switcher with HV Startup and SenseFET onsemi FSL5x8A/H is an integrated peak-current-mode controlled pulse width modulation (PWM) power switch specifically designed for off-line switch-mode power supplies. The PWM controller includes an advanced soft-start, frequency hopping, optimized gate driver, internal transconductance amplifier, temperature-compensated precise current source for loop compensation, and enhanced self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSL5x8A/H allows users to reduce total cost, component count, size, and weight while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform for the cost-effective design of both isolated and non-isolated flyback converters.

Features
  • Rugged 800 V FET with 3.8 Ω or 6.3 Ω typical RDS(ON) with built-in HV current source for start-up
