FAN7547A LCD Backlight Inverter Drive IC February 2007 FAN7547A LCD Backlight Inverter Drive IC Features Description Backlight Lamp Ballast and Soft Dimming The FAN7547A provides all control functions for a Reduced Number of Components current-fed, push-pull, self-oscillation type converter and Wide Range of Operating Voltage (6 to 30V) also contains a pulse-width-modulated (PWM) controllerto develop a supply voltage. Typical operating frequency Precision Voltage Reference Reduced to 3.4% range is from 30kHz to 100kHz, depending on the cold Low Standby Current (Typically 50µA) cathode fluorescent lamp (CCFL) and the transformer s Soft-Start Function characteristics. PWM ControlAnalog, Mixed, and PWM Dimming Function 14-SOP P-Channel MOSFET DriveOpen-Lamp Protections (OLP)Shutdown Protections (SDP)14-Pin SOP Ordering Information Part Number Package Pb-Free Operating Temperature Range Packing Method FAN7547AM Tube 14-SOP Yes -25°C ~ +85°C FAN7547AMX Tape & Reel © 2005 Fairchild Semiconductor Corporation FAN7547A Rev. 1.0.3 FAN7547A LCD Backlight Inverter Drive IC Internal Block Diagram OUT V 1 CC V V Z ref SW Vref 3V Output 2A V Internal Driver Q R SDP
