FAN7710 — Ballast Control IC for Compact Fluorescent Lamps June 2007 FAN7710 Ballast Control IC for Compact Fluorescent Lamps 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 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. FAN7710 incorporates a preheating / ignition function, controlled by an user-selected external capacitor, to increase lamp life. The FAN7710 detects switch operation from after ignition-mode through an internal active Zero-Voltage Switching (ZVS) control circuit. This control scheme enables the FAN7710 to detect an open-lamp condition, without the expense of external circuitry, and prevents stress on MOSFETs. The high-side driver built into the FAN7710 has a commonmode noise cancellation circuit that provides robust operation against high-dv/dt noise intrusion. 8-DIP Applications Compact Fluorescent Lamp Ballast Ordering Information Part Number FAN7710N Package 8-DIP Pb-Fre……
