FSBH0270 - Green Mode Fairchild Power Switch

Download the FSBH0270 datasheet PDF. This datasheet also covers the FSBH0170 variant, as both devices belong to the same green mode fairchild power switch family and are provided as variant models within a single manufacturer datasheet.

General 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 Switch Mode Power Supplies (SMPS) with minimal external components.

Key Features

  • Brownout Protection with Hysteresis.
  • Built-In 5ms Soft-Start Function.
  • Internal Avalanche-Rugged 700V SenseFET.
  • No 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.
  • VDD Under-Voltage Lockout (UVLO).
  • VDD Over-Voltage Prote.
