FAN7711 Datasheet | Fairchild Semiconductor

Features Description - Floating Channel for Bootstrap Operation to +600V The FAN7711, developed with Fairchild’s unique high- - Low Start-up and Operating Current: 120μA, 3.2m A voltage process, is a ballast control integrated circuit (IC) for a fluorescent lamp. FAN7711 incorporates a preheating - Under-Voltage Lockout with 1.8V of Hysteresis - Adjustable Run Frequency and Preheat Time IG - Internal Active ZVS Control S - Internal Protection Function (Latch Mode) D DE - Internal Clamping Zener Diode - High Accuracy Oscillator - Soft-Start Functionality INUFORemi N Applications ED ns TIO - Electronic Ballast / ignition function, controlled by an user-selected external capacitor, to increase lamp life. The FAN7711 detects switch operation from after ignition mode through an internal active Zero-Voltage Switching (ZVS) control circuit. This control scheme enables the FAN7711 to detect an open-lamp condition, without the expense of external circuitry, and prevents stress on MOSFETs. The high-side driver built into the FAN7711 has a monmode noise cancellation circuit that provides robust operation against high-dv/dt noise intrusion. 8-SOP 8-DIP ONTMCETNYDORUINRFo ORMA Ordering Information C T RE NTA FO Part Number O O E FAN7711N ISIS N E C TIV FAN7711M S TA FAN7711MX Package 8-DIP 8-SOP DVICE PLEA SEN Typical Application THIS DE REPRE R1 Pb-Free Yes Operating Temperature Range -25°C ~ 125°C Packing Method Tube Tube Tape & Reel D5 R3 D6 U1 D1 D2 VDD 1 8...
