Description
General part information
TPS922053 Series
The TPS92205x family is a 2A / 4A non-synchronous Buck LED driver with 4.5V to 65V wide input range. By integrating the low-side 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 anode connection and single layer PCB design. The switching frequency is configurable from 100kHz to 2.2MHz with optional spread spectrum feature for better EMI performance.
The TPS92205x 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 TPS92205x 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.
