The Infineon Technologies TLD55412QVXUMA1 is a dual-channel synchronous DC/DC controller suitable for high-power LED driver applications. It operates within a wide input voltage range of 4.5V to 40V for the IC and 4.5V to 55V for power, with a switching frequency adjustable from 200 kHz to 700 kHz. The device supports multiple topologies, including Step-Down (Buck) and Step-Up (Boost), and offers LED current accuracy of ±3%.
Designed for the harsh automotive environment, this controller features advanced protection functions and enhanced dimming capabilities with both analog and PWM control. It is available in a thermally enhanced PG-VQFN-48-31 package, suitable for surface mount applications. The TLD55412QVXUMA1 also boasts a maximum efficiency of up to 96%.
Key features include SPI for diagnostics and control, a Limp Home Function (Fail Safe Mode), and an EMC-optimized design with auto Spread Spectrum. The controller provides LED current sense with a dedicated monitor output and supports multiple loads with fast output discharge operation.
