General Description

The MAX1804 feedback integrator is designed to improve voltage regulation in power-supply systems. The device corrects line- and load-regulation problems, and can be used to compensate for voltage drops in power-management distribution lines.

The regulation set point is determined by an external reference voltage applied at the ADJ pin. The differ ence between that reference and MAX1804 feedback is integrated, and a correction current is applied to the voltage regulator’s feedback.
