The ADP1046A is a flexible secondary-side digital controller for AC-DC and isolated DC-DC converters. It has multiple features including integrated typical PWM controller functions, programmable loop filters, programmable input line voltage feedforward, remote and local voltage detection, primary-side and secondary-side current detection, synchronous rectification control, current sharing, and redundant OrFET control.
The ADP1046A is a flexible secondary-side digital controller designed for use in AC-DC and isolated DC-DC converters. It integrates all typical PWM controller functions, including seven PWM control signals, digital loop control, an integrated programmable loop filter, and programmable input line voltage feedforward.
The device offers extensive fault detection and protection features, along with fast digital calibration and user-accessible EEPROM for programming loop filters and timing controls. Powered by a single 3.3 V supply in a 32-lead LFCSP package, it supports applications such as server power systems, memory, network infrastructure, and communication equipment.
