iW7032 - 32-Channel LED Driver

Description

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.

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 converters to optimize the system power efficiency. The iW7032 also provides 32 constant current sinks with maximum ±2% current matching. The LED PWM dimming can be adjusted dynamically through a high bandwi.

iW7032 32-Channel LED Driver for LCD Panel Backlighting 1 Description 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-connected LEDs. The 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 converters to optimize the system power efficiency.
