FSBH0270 - Green Mode Fairchild Power Switch

This page provides the datasheet information for the FSBH0270, a member of the FSBH0170 Green Mode Fairchild Power Switch family.

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.

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.
