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.

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.
