The Infineon TLD5191ES is a synchronous MOSFET H-Bridge DC-DC controller featuring built-in protection. This device is optimized for driving high-power LEDs in automotive applications, offering maximum system efficiency with a minimal number of external components. It supports both analog and digital (PWM) dimming, along with an embedded PWM engine.
The TLD5191ES operates within an input voltage range of 4.5V to 40V for the device and 4.5V to 55V for the power stage. The switching frequency is adjustable between 200 kHz and 700 kHz. Key electrical specifications include a maximum efficiency of up to 96%, LED current accuracy of ±3%, and typical H-Bridge NMOS driver on-state resistance values of 2.3 Ω (gate pull-up) and 1.2 Ω (gate pull-down) at 25°C.
Diagnostic outputs for overvoltage, shorted LED fault, and overtemperature are provided. The device is EMC optimized with spread spectrum frequency modulation activated by default. It is qualified for automotive applications according to AEC-Q100, Grade 1.
The TLD5191ES is housed in a TSDSO-24-5 package and is designed for surface mount applications. Its suitability for the automotive environment makes it ideal for exterior lighting such as full LED headlamp assemblies, pixel lights, and as a voltage pre-regulator for rear lamp assemblies.
The device input supply voltage range is 4.5 V to 40 V, and the power stage input voltage range is 4.5 V to 55 V.
The switching frequency range is adjustable from 200 kHz to 700 kHz.
The maximum efficiency is up to 96%.
The LED current accuracy is ± 3%.
It offers enhanced dimming features including analog and PWM dimming.
The TLD5191ES is available in a TSDSO-24-5 package.
