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 can be adjusted from 20mA to 75mA for each
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.
Applications
· LCD Display Modules
· LCD Monitor

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
