LITIX™ Power

TLD5098EP- Multitopology LITIX™ Power DC/DC Controller IC

Overview

Description

The TLD5098EP is a flexibly usable DC/DC boost controller with built in

diagnosis and protection features especially designed to drive LEDs.

It is designed to support fixed current and fixed voltage configurations in

multiple topologies such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external

components. The TLD5098EP drives a low side n-channel power MOSFET from an internal 5 V linear regulator.

The switching frequency is adjustable in the range from 100 kHz to 500 kHz and can also be synchronized to

an external clock source.

The TLD5098EP can be flexibly dimmed by means of analog and PWM dimming; an enable function reduces

the shut-down current consumption to I_{Q_OFF}< 10 µA.

The current mode control scheme of this device provides a stable regulation loop maintained by small

external compensation components. Additionally an integrated soft start feature limits the current peak as

well as voltage overshoot at start-up. This IC is suited for use in the harsh automotive environments.
