TLD5097EP

The Infineon TLD5097EP is a flexibly usable DC/DC boost controller IC with built-in diagnosis and protection features, specifically designed to drive LEDs. It supports fixed current and fixed voltage configurations in various topologies including Boost, Buck, Buck-Boost, SEPIC, and Flyback by adjusting external components.

This controller IC operates within a wide input voltage range of 4.5 V to 45 V and features an adjustable switching frequency from 100 kHz to 500 kHz, which can also be synchronized to an external clock source. The TLD5097EP is designed to drive a low-side n-channel power MOSFET from an internal 5 V linear regulator. It offers flexible dimming capabilities through analog and PWM dimming, and an enable function that reduces shutdown current consumption to less than 10 µA.

Suited for harsh automotive environments, the TLD5097EP includes integrated protection and diagnostic functions such as open circuit detection, output overvoltage protection, and overtemperature shutdown. It also features an internal soft-start function to limit current peaks and voltage overshoot during startup. The device is available in a small, thermally enhanced 14-pin PG-TSDSO-14 package and is qualified for automotive applications according to AEC-Q100/101.

Potential applications include automotive exterior and interior lighting, general illumination, and general-purpose current/voltage-controlled DC/DC drivers.
