The device is ideal for MR16 and AR111 applications, which require good patibility to DC and AC voltages and electronic transformers. The hysteretic control scheme does not need control loop pensation while providing the benefits of fast transient response and high power factor. The patent pending feedback control method allows the output power to be determined by the number of LED used without ponent change. The TPS92560 supports both boost and SEPIC configurations for the use of different LED modules.
