TPS923655DRRR

The TPS92365x family is a 2-A / 4-A nonsynchronous Boost / Buck-Boost LED driver with 4.5-
V to 65-V wide input range. By integrating the lowside NMOS switch, the device is capable of driving
LEDs as well as charging batteries 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 optional spread spectrum
feature for better EMI performance.
The TPS92365x 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 TPS92365x family also provides multiple
systematic protections, including LED open and short,
sense resistor open and short, configurable thermal
foldback and thermal shutdown. A Fault output
sends out acknowledge signals as soon as any fault
condition is detected.
