代理*A708 3路20mA LED线性恒流驱动IC

A708 3 CHANNELS 20mA ADVANCED CURRENT REGULATOR

GENERAL D*CRIPTION

        The A708 is a 3 channels 20mA advanced current regulator for driving LEDs. Only b** 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, *art phone, PDA, notebook, and monitor, etc.

APPLICATIONS

• Small Size Color LCD Backlights.

•Mobile Phone, Smart Phone.

•LED Backlight for Portable DVD, *, Monitors and UMPC.

FEATUR*

•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 *D protection.

•Advanced Bi-CMOS process.
