AP3616 Datasheet | BCD Semiconductor

Data Sheet SIXTEEN-CHANNEL, 75m A 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 (75m A 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 20m A to 75m A for each channel. The LED lightness can be adjusted by PWM dimming function. - - - Current Match Accuracy (Typical): ±1.5% PWM / Linear Dimming Control 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 - LCD TV Jul. 2012 Rev. 1. 2 SOIC-28 HSOP-28 Figure 1.
