A708 3 CHANNELS 20mA ADVANCED CURRENT REGULATOR
 
GENERAL 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.
 
APPLICATIONS
• Small Size Color LCD Backlights.
•Mobile Phone, Smart Phone.
•LED Backlight for Portable DVD, NB, Monitors and UMPC.
 
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.
