The TPS922152 is non-synchronous Average-Current control Buck LED drivers with 4.5V to 500V wide application voltage range. The TPS922152 is capable of driving external switching FETs at adjustable switching frequency up to 1MHz with Adative Off-Time (AOT) mode. The AOT mode allows low LED current ripple and fast transient response with small output capacitor. The device also supports single layer PCB design and common anode connection.
The TPS922152 supports high-accuracy and high-ratio analog dimming by configuring analog signals through the ADIM input pins. The full-scale output current is configured by an external resistor and high analog dimming ratio is achievable by the unique corrective sensing. The device also supports high-frequency and high-ratio PWM dimming by configuring simple high and low signals through the PDIM input pins. High-accuracy and high-ratio of PWM dimming is achievable by the unique inductive fast dimming (IFD).
The TPS922152 also provides multiple systematic protections, including LED open and short, sense resistor open and short.
