TLD5098EL - Infineon

TLD5098EL Power DC/DC Controller

The TLD5098EL 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 TLD5098EL drives a low .

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 TLD5098EL 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 TLD5098EL can be flexibly dimmed by means of analog and PWM dimming; an enable function reduces the shut-down current consumption to IQ_OFF < .
