A708

www.DataSheet4U.com A708 www.addmtek.com DESCRIPTION The A708 is a 3 channels 20mA advanced current regulator for driving LEDs. Only bypass capacitor is required and the noise is very low. The special circuit design provides over 90% efficiency because of the very low dropout voltage. Target end applications are LED backlights for color LCD display, such as mobile phone, smart phone, PDA, notebook, and monitor, etc. „ „ „ „ „ „ „ „ „ ADVANCED 3 CHANNELS 20mA CURRENT REGULATOR FEATURES Fixed 20mA DC constant sink current. Individual current sink circuit for each LED string to prevent short / open circuit on LEDs. TSOT-26 package available. High efficiency. Supply voltage range 2.7V ~ 12V. Output sustaining voltage up to 17V. 0.1uA standby current. 2KV HBM ESD protection. Advanced Bi-CMOS process. APPLICATIONS „ TYPICAL APPLICATION CIRCUIT Small Size Color LCD Backlights.
