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

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.
