SIXTEEN-CHANNEL, 75mA CURRENT SINK WITH CURRENT MATCH AP3616
General Description
Features
The AP3616 is an sixteen-channel constant current _{· Input Voltage Range: 4.2V to 27V}
sink with current match used for LED driver. It uses an _{· Maximum Output Current: Typical 1.2A (75mA}
external resistor to set the current for sixteen LED
per Channel)
strings with an accuracy of ±1.5%. The full scale LED _{· Current Match Accuracy (Typical): ±1.5%}
current can be adjusted from 20mA to 75mA for each _{· PWM / Linear Dimming Control}
channel. The LED lightness can be adjusted by PWM
dimming function.

Open LED Self-check and Protection
Flexible Short LED Protection
The device can keep working normally without any ^{· Under Voltage Lockout Protection}
damage when LEDs are short or open. It features under ^{· Over Temperature Protection}
voltage lockout protection and over temperature pro- · FBX and SYN Pins Enable Parallel Application
tection.
· Over Voltage Protection
The AP3616 has three interface terminals (FB, SYN
and FBX pins). The FB and SYN pins allow the device
to work with a DC/DC converter to drive LED arrays
for good performance. And the FBX pin enables the
device to be connected in parallel.
The AP3616 is available in SOIC-28 and HSOP-28
packages.
