SG6846A - Highly Integrated Green-Mode PWM Controller

Description

The SG6846A is especially designed for SMPS with surge-current output, incorporated with a two-level OCP function.

Features

  • Low Startup Current: 8µA.
  • Low Operating Current: 3.7mA.
  • Peak-Current Mode of Operation with Cycle-by- Cycle Current Limiting.
  • PWM Frequency Continuously Decreasing with Burst Mode at Light Loads.
  • VDD Over-Voltage Protection (OVP).
  • AC Input Brownout Protection with Hysteresis.
  • Constant Output Power Limit (Full AC Input Range).
  • Internal Latch Circuit for OVP, OTP, and OCP.
  • Two-level OCP Delay: 1600ms.
  • Output Short-Circuited Delay Time: 100ms.
