SG6858 - Green-Mode PWM Controller

General Description

This highly integrated PWM controller provides several special enhancements designed to meet the low standby-power needs of low-power SMPS.

Key Features

  • Green-Mode PWM.
  • Supports the ”Blue Angel” Standard.
  • Low Startup Current: 10µA (Maximum).
  • Low Operating Current: 2.5mA.
  • Leading-Edge Blanking (LEB).
  • Constant Output Power Limit.
  • Built-in Synchronized Slope Compensation.
  • Current-Mode Operation.
  • Cycle-by-Cycle Current Limiting.
  • Under-Voltage Lockout (UVLO).
  • Programmable PWM Frequency.
  • VDD Over-Voltage Protection with Auto-Restart.
  • Gate Output Voltage Clamped at 17V.
  • Few External.
