TLD5190QU Description

Short technical summary and product information.

The Infineon TLD5190QU is a synchronous MOSFET H-Bridge DC/DC controller designed for high-power LED applications. It features a wide input voltage range from 4.5 V to 55 V and supports LED forward voltages from 2 V to 55 V. This device operates with a switching frequency adjustable between 200 kHz and 700 kHz, offering maximum efficiency up to 96%.

The TLD5190QU provides both constant current (LED) and constant voltage regulation, along with advanced protection features including overload, shorted load, open load, and overvoltage protection. It also includes diagnostic outputs for fault detection and enhanced dimming capabilities via analog and PWM signals. The device is EMC optimized with an auto Spread Spectrum feature and is available in PG-VQFN-48-31 or PG-TQFP-48-9 packages.

Designed for the harsh automotive environment, the TLD5190QU is AEC qualified. Its current mode regulation scheme ensures a stable control loop, and an adjustable soft-start feature limits inrush current and voltage overshoot during startup. The controller supports synchronization to an external clock source for improved system integration.
