Power controller IC from ADI for AC/DC
and DC/DC converters
Analog Devices 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 ADP1043A featuring 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. The ADP1046 is specifically designed for high
efficiency AC-to-DC power supplies used in server, storage
and networking applications and isolated DC-to-DC supplies
including intermediate bus and radio power amplifier applications.
The ADP1046 is suited to parallel and redundant power supply
operation and offers analog and digital current sharing
functions and control of the external OR-FET for redundant
power supply applications.
The other key features:
Dedicated loop filters for soft start, light load and normal
load offer improved. loop response and enhance design flexibility.
Adaptive dead-time control for improved efficiency across
the entire load range.
Current share and OR-ing control for use in parallel and
redundant systems.
User accessible 8K byte EEPROM.
