Texas Instruments TPS92365x 2A/4A Non-Synchronous Boost/Buck-Boost LED Drivers have a 4.5V to 65V wide input range. By integrating the low-side NMOS switch, the devices can drive LEDs and charge batteries with high power density and high efficiency. The TPS92365x also supports common anode 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 TPS92365x supports four dimming options: analog, PWM, hybrid, and flexible. Each dimming method can be configured through the PWM and ADIM input pins using simple high and low signals. The TPS92365x adopts an adaptive off-time current mode control and smart and accurate sampling to enable inductive fast dimming (IFD) and achieve high dimming accuracy.
The Texas Instruments TPS92365x 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.
