The Infineon LITIX power is a flexibly usable DC/DC boost controller with built in diagnosis and protection features especially designed to drive LEDs. It also includes a pulse width modulator to easily implement a dimming function with reduced color shifting and a spread spectrum modulator to improve the EMI performance. It is designed to support fixed current and fixed voltage configurations in multiple topologies such as boost, buck, buck-boost, SEPIC and fly back by simply adjusting the external components.

Drives low-side external n-channel switching MOSFET from internal 5 V voltage regulator
Flexible switching frequency range from 100 kHz to 500 kHz with spread spectrum modulator
Synchronization with external clock source
