Description
General part information
LP8865X-Q1 Series
The LP8865-Q1 family is a non-synchronous multi-topology solution with 4.5-V to 65-V 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 configurable from 100 kHz to 2.2 MHz with an optional spread spectrum feature for better EMI performance.
The LP8865-Q1 family supports four dimming options, including analog, PWM, hybrid and flexible dimming. Each dimming method can be configured through the PWM and ADIM input pins by means of simple high and low signals. The family adopts an adaptive off-time current mode control along with smart and accurate sampling to enable inductive fast dimming (IFD) and achieve high dimming accuracy.
The LP8865-Q1 family also provides multiple systematic protections, including LED open and short, sense resistor open and short, configurable thermal foldback and thermal shutdown. Fault output will send out acknowledge signals as soon as any fault condition is detected.
