一華半導體股份有限公司 MOSDESIGN SEMICONDUCTOR CORP. EL CONTROLE M5003 EL LAMP DRIVER IC GENERAL DESCRIPTION 功能叙述 The M5003 is CMOS chip design for Electro-luminescence Lamp (EL) to light has independent circuit to control switching and EL driver frequency circuit, The switching frequency is decided by CKX, If OSC connect a resistor to VDD, or connect a capacitor to VSS the switching frequency can be adjusted. Delay function can be implement if ON connect a capacitor to VSS. The time of delay is decided by the value of capacitor. FEATURES 产品特长 • DC to AC conversion • Built-in RC oscillator • Two trigger inputs TG : active High TGB : active Low • Adjustable EL driver frequency by CKX • Adjustable Switching frequency by CHOPX APPLICATIONS 产品应用 • EL display BLOCK DIAGRAM 功能方块图 OSC Oscillator CKX Divider Inductor Driver CHOP CHOPX Oscillator ON Oscillator Delay Time Divider EL Driver CK TGB TG S1 S2 Control Logic *All specs and applications shown above subject to change without prior notice.
