The TLD5097EP is a LED boost controller with built in protection features
The controller concept of the TLD5097EP allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. Thanks to this the TLD5097EP is a quite easy to use and flexible device that comes without SPI but still with a quite powerful feature set. It is very similar to TLD5098EP but without a dedicated PWM driver and without short to ground protection. Therefore it is a good alternative device for applications where the electronic is integrated in the same housing with the load like it is often the case for separately placed day-time-running lights or in some cost-effective LED headlamps.
Summary of Features
Single-Channel Multitopology (B2B, B2G, SEPIC, Flyback) DC-DC Controller

Synchronization with external clock source
PWM Dimming
Analog Dimming feature to adjust average LED current
Internal 5 V Low Drop Out Voltage Regulator
Open Circuit Detection
Output Overvoltage Protection
Internal Soft Start
Over Temperature Shutdown
300mV High Side Current Sense to ensure highest flexibility and LED current accuracy
Available in a small thermally enhanced PG-TSDSO-14 package

Potential Applications
Automotive interior and exterior lights
LED daytime running lights, Low Beam, High Beam or combined Low- and Highbeams
Pre-regulator e.g. for rear light applications
Applications
Automotive instrument cluster
Automotive LED lighting systems
