3 Description
The LP8865-Q1 family is a non-synchronous multitopology
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.
