3 CHANNELS 20mA
ADVANCED CURRENT REGULATOR
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.
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.
Supply voltage range 2.7V ~ 12V.
Output sustaining voltage up to 17V.
0.1uA standby current.
2KV HBM ESD protection.
Advanced Bi-CMOS process.
