Description
The highly integrated FSBH-series consists of an integrated current-mode Pulse Width Modulator (PWM) and an avalanche-rugged 700V SenseFET. It is specifically designed for high-performance offline Switched-Mode Power Supplies (SMPS) with minimal external components.

FEATUREs
  Brownout Protection with Hysteresis
  Built-In 5ms Soft-Start Function
  Internal Avalanche-Rugged 700V SenseFET
  Low Acoustic Noise During Light-Load Operation
  High-Voltage Startup
  Linearly Decreasing PWM Frequency to 18KHz
  Peak-Current-Mode Control
  Cycle-by-Cycle Current Limiting
  Leading-Edge Blanking (LEB)
  Synchronized Slope Compensation
  Internal Open-Loop Protection
  VDDUnder-Voltage Lockout (UVLO)
  VDDOver-Voltage Protection (OVP)
  Internal Auto-Restart Circuit (OVP, OTP)
  Constant Power Limit (Full AC Input Range)
  Internal OTP Sensor with Hysteresis
  VIN Pin for Pull-HIGH Latch Function and Pull-LOW Auto-Recovery Protection
