The controller concept of the TLD5098EL allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. Thanks to this the TLD5098EL is a quite easy to use and flexible device that comes without SPI but still with a quite powerful feature set.TLD5098EL is a perfect choice when diagnostic as well as advanced dimming functionality like analog and digital dimming are required and where a DC-DC boost concept is needed like for Day-time-running lights or combined Low-/High-Beams.

This concept of a synchronous and seamless buck-boost regulation provides a very efficient solution for circuits where the output (load) voltage is on the same level as the input voltage, e.g. in short chains with 2 to 3 high power LEDs or laser diodes connected to a 12 V electrical system.Thanks to the flexibility to be used in current and in voltage mode it is also a perfect device for powering non LED applications like USB and mobile wireless charger or as multipurpose pre-regulation like for infotainment.As it comes without SPI it is also ideal for all application where a basic feature set is sufficient or where a Microcontroller is not used.

The TLD6099-2ES is a dual channel multi-topology DC-DC controller for LED applications with built-in protection features for a compact LED driver. Each channel drives an external NMOS to discharge the output capacitance fast, managing load variations. Typical user cases are switching from low beam to high beam or driving adaptive driving beam with matrix manager.
