General Description
The AP3616 is an sixteen-channel constant current
sink with current match used for LED driver. It uses an
external resistor to set the current for sixteen LED
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.
The device can keep working normally without any
damage when LEDs are short or open. It features under
voltage lockout protection and over temperature pro-
tection.
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.
