Infineon Technologies TLD5099EP DC/DC controller

The TLD5099EP is the newest member of the well-established LITIX Power Family. It is a LED boost controller with built-in protection features. The controller concept of the TLD5099EP allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC, and Flyback by simply adjusting the external components. Thanks to this the TLD5099EP is a quite easy to use and flexible device that comes without SPI but still with a quite powerful feature set. The main difference between the other family members TLD5097EP and TLD5098EP is an integrated spread spectrum feature and an integrated PWM engine.
