LEDs are the big enabler in automotive front lighting, supporting new design possibilities, energy savings and new applications like matrix or laser high beam. These trends come with the demand for flexible DC/DC driver solutions for driving LED systems up to 50 W and more – or LEDs in configurations with currents of even more than 3 A – with high efficiency. The TLD5541-1QV is the first member of Infineon’s new multitopology DC/DC controller family LITIX™ Power Flex. Its synchronous DC/DC H-bridge topology is beneficial for driving high-power LEDs with maximum system efficiency (well above 90%), and a minimum number of external components. Furthermore, reduced EMC emissions are achieved thanks to the optimized spread spectrum switching frequency. With its seamless buck-boost regulation and fast dynamic load jump behavior, it is also an innovative solution for realizing cost-optimized LED headlamps with complete protection and diagnosis features – e.g. by driving two, three or more separately switched LED loads in one string, with up-to 55 V string voltage, with just one TLD5541-1QV.
