The LP8865C-Q1 family is a low cost non-synchronous multi-topology solution with 4.5V to 65V wide input range. By integrating the low-side NMOS switch, the device is capable of driving LEDs with high power density and high efficiency. The family also supports common cathode connection and single layer PCB design. The switching frequency is fixed with 400kHz.
The LP8865C-Q1 family support PWM dimming by configuring through the DIM input pins by means of simple high and low signals or analog dimming by configuring through the DIM input pins by means of analog voltage signals. The device adopts an adaptive off-time current mode control along with smart and accurate sampling to enable fast PWM dimming and achieve high-dimming ratio.
The LP8865C-Q1 family also provides multiple systematic protections, including LED open and short, switching FET open and short, sense resistor open and short, and thermal shutdown.
