A708
3 CHANNELS 20mA
ADVANCED CURRENT REGULATOR
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.
TYPICAL APPLICATION CIRCUIT
VLED+
CBP
APPLICATIONS
„ Small Size Color LCD Backlights.
„ Mobile Phone, Smart Phone.
„ LED Backlight for Portable DVD, NB, Monitors,
and UMPC.
