A80804 Overview
The A80804 and A80804-1 are linear, programmable current controllers capable of accurately regulating current in four LED strings using external MOSFETs. Each of the four LED drivers has an independent enable/PWM input and current-sense resistors and can be independently dimmed with an external PWM signal, or all channels can be dimmed with internal PWM dimming and automatic phase shifting. The overall LED current...
