Analog Devices Inc. has introduced the ADP1046 digital power controller for high efficiency AC-to-DC and isolated DC-to-DC power supply systems.
The ADP1046 is a flexible controller with seven PWM (pulse width modulation) logic outputs that can be easily programmed using an easy-to-use graphic user interface (GUI) with I2C interface. The device can be used to control and drive most power supply topologies, including resonant mode for high efficiency. The ADP1046 is pin compatible with ADI’s, ADP1043A but offers advanced features and greater flexibility, including voltage feed-forward for fast line transient response; dedicated control loop configuration to improve loop response and reduce output noise; and adaptive dead-time control for enhanced efficiency across the entire load range.
