FAN7710 - Ballast Controller

General Description

The FAN7710, developed using Fairchild’s unique highvoltage process and system-in-package (SiP) concept, is a ballast control integrated circuit (IC) for a compact fluorescent lamp (CFL).

The FAN7710 controls internal high-voltage stress and delivers 20W to the lamp at 310VDC voltage.

Key Features

  • Integrated Half-Bridge MOSFET.
  • Floating Channel for Bootstrap Operation up to +550V.
  • Low Start-up and Operating Current: 120μA, 2.6mA.
  • Under-Voltage Lockout with 1.8V of Hysteresis.
  • Adjustable Run Frequency and Preheat Time.
  • Internal Active ZVS Control.
  • Internal Protection Function (No Lamp).
  • Internal Clamping Zener Diode.
  • High Accuracy Oscillator.
  • Soft-Start Functionality.
