GENERAL DESCRIPTION
The ADP1053, based on a voltage mode PWM architecture, is a flexible, application dedicated digital controller designed for isolated and nonisolated dc-to-dc power supply applications. The ADP1053 enables highly efficient power supply design and facilitates the introduction of intelligent power management techniques to improve energy efficiency at a system level.
The ADP1053 provides control, monitoring, and protection of up to three independent channel outputs. The eight flexible PWM outputs can be configured as three independent channels: two regulated channels with feedback contro...
