The LP8865-Q1 family is a
non-synchronous multi-topology option 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
configurable from 100kHz to 2.2MHz, 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 sends out acknowledge signals as soon as any
fault condition is detected.
