The TLD5098EP is a LED boost controller with built in protection features
The controller concept of the TLD5098EP allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. Thanks to this the TLD5098EP is a quite easy to use and flexible device that comes without SPI but still with a quite powerful feature set.
TLD5098EP 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.
Summary of Features
Single-Channel Multitopology (B2B, B2G, SEPIC, Flyback) DC-DC Controller
Constant Current or Constant Voltage Regulation
Wide Input Voltage Range from 4.5 V to 45 V
Very Low Shutdown Current: Iq_OFF < 10 μA
Switching Frequency Range from 100 kHz to 500 kHz
Synchronization with external clock source
PWM Dimming (integrated Gate driver for high accuracy)
Analog Dimming feature to adjust average LED current
Open Circuit Detection
Short to GND Protection
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
Automotive AEC Qualified
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
