Infineon, DC-DC Controller 48-Pin, PG-VQFN-48-31 TLD5190QVXUMA1

The Infineon LITIX Power 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 TLD5190 offers both analogue and digital dimming. The switching frequency is adjustable in the range of 200 kHz to 700 kHz. It can be synchronized to an external clock source. A built in spread spectrum switching frequency modulation and the forced continuous current regulation mode improve the overall EMC behaviour. 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.
