AX2008 - White LED Backlight Controller

General Description

The AX2008 is a step-up current mode PWM DC/DC converter with built-in power MOSFET and eight channel current sources.

It is designed for driving white LED arrays for medium size LCD panel backlight applications.

Key Features

  • dynamic output voltage control function, which automatically chooses the lowest sense voltage of multiple channels to regulate the feedback voltage of step-up converter. Through the function, the AX2008 is able to dynamically adjust output voltage of step-up converter to optimize the system power efficiency. The internal step-up converter provides soft-start feature which is determined by external compensation components. The switching frequency is programmable by an external resistor, which is.
