SG6848DZ1 - Green-Mode PWM Controller

Download the SG6848DZ1 datasheet PDF. This datasheet also covers the SG6848TZ1 variant, as both devices belong to the same green-mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

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

To minimize standby power consumption, the proprietary Green Mode provides offtime modulation to continuously decrease PWM frequency under light-load conditions.

Key Features

  • Green-Mode PWM Controller.
  • Low Startup Current: 5 μA.
  • Low Operating Current: 3 mA.
  • Programmable PWM Frequency.
  • Peak-Current-Mode Operation.
  • Leading-Edge Blanking.
  • Built-in Synchronized Slope Compensation.
  • Cycle-by-Cycle Current Limiting.
  • Constant Output Power Limit.
  • Gate Output Voltage Clamped at 15 V.
  • Small SSOT-6 Package.
