A708中文资料广鹏科技数据手册PDF规格书

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.
