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 to the other family members TLD5097EP and TLD5098EP is an integrated spread spectrum feature and an integrated PWM engine.

Key features

• Constant current or constant voltage regulation
• Switching frequency range from 100 kHz to 500 kHz
• Synchronization with external clock source
• Analog dimming and PWM dimming feature to adjust average LED current

Additional features

• Integrated PWM Engine and spread spectrum feature
• PWMO gate driver for PWM dimming and output disconnection
• Open circuit detection, short to GND protection, output overvoltage protection
• Internal soft start,  over temperature shutdown

Applications

• Automotive Interior and Exterior Lights
• Pre-Regulator for Rear Light Applications
• Daytime Running LED Lights
