1 / 16 page  SIXTEEN-CHANNEL, 75mA CURRENT SINK WITH CURRENT MATCH AP3616 Data Sheet 1 BCD Semiconductor Manufacturing Limited Jul. 2012 Rev. 1. 2 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. Features · Input Voltage Range: 4.2V to 27V · Maximum Output Current: Typical 1.2A (75mA per Channel) · Current Match Accuracy (Typical): ±1.5% · PWM / Linear Dimming Control · Open LED Self-check and Protection · Flexible Short LED Protection · Under Voltage Lockout Protection · Over Temperature Protection · FBX and SYN Pins Enable Parallel Application · Over Voltage Protection Applications · LCD Display Modules · LCD Monitor · LCD TV Figure 1.
