Description
General part information
TLD5191ESXUMA1
The TLD5191ES is a synchronous MOSFET H-Bridge DC-DC controller with built-in protection features. This concept is beneficial for driving high power LEDs with maximum system efficiency and minimum number of external components. The TLD5191ES offers analog and digital (PWM) dimming and embedded PWM engine. The switching frequency is adjustable in the range of 200 kHz to 700 kHz. A built-in spread spectrum switching frequency modulation and the forced continuous current regulation mode improve the overall EMC behavior. Furthermore, the current mode regulation scheme provides a stable regulation loop maintained by small external compensation components. The adjustable soft start feature limits the current peak as well as voltage overshoot at start-up. The TLD5191ES is suitable for use in the automotive environment and in industrial and consumer applications as well (e.g. wireless charging).
