The TLD5097EL from Infineon Technologies is a flexible DC/DC boost controller with integrated diagnosis and protection features, specifically designed for driving LEDs. It supports various topologies including Boost, Buck, Buck-Boost, SEPIC, and Flyback by adjusting external components.
This controller operates with a wide input voltage range from 4.5V to 45V and features an adjustable switching frequency from 100 kHz to 500 kHz, which can also be synchronized to an external clock. The TLD5097EL includes analog and PWM dimming capabilities for adjusting average LED current and an enable function that reduces shutdown current consumption to less than 10 µA.
Designed for harsh automotive environments, the TLD5097EL drives a low-side n-channel power MOSFET from an internal 5V linear regulator. It incorporates current mode control for stable regulation and an integrated soft-start feature to limit current peaks and voltage overshoot during startup. Protection and diagnostic functions include open circuit detection, output overvoltage protection, and overtemperature shutdown.
The device is available in a PG-SSOP-14-3 package, suitable for surface mount applications.
The input voltage range is 4.5 V to 45 V.
The switching frequency is adjustable from 100 kHz to 500 kHz.
The shutdown current consumption is less than 10 µA.
It is available in a PG-SSOP-14-3 package.
