iW7032 Datasheet (Dialog Semiconductor)

iW7032, 32-Channel LED Driver

The iW7032 is a high efficiency driver for LEDs.

It is designed for use with mid-to-large size LCD panels that use arrays of LEDs as a backlight source.

It is able to communicate with up to two external step-up or step-down PWM DC-DC converters to drive up to 32 separate strings of multiple series-c

iW7032 Features

* dynamic output voltage control, which automatically chooses the lowest active LED source voltage to regulate the feedback voltage of a step-up or step-down converter. Through this function, the iW7032 is able to dynamically adjust the output voltage of up to two external step-up or step-down convert
