APPLICATIONS
High density, isolated dc-to-dc power supplies
Intermediate bus converters
High availability parallel power systems
Server, storage, industrial, networking, and communications
infrastructure
The ADP1050 is an advanced digital controller with a PMBus™
interface targeting high density, high efficiency dc-to-dc power
conversion. This controller implements voltage mode control
with high speed, input voltage feedforward operation for
enhanced transient and noise performance. The ADP1050 has
four programmable pulse-width modulation (PWM) outputs
capable of controlling most high efficiency power supply
topologies, with the added control of synchronous rectification (SR).
The ADP1050 implements several features to enable a robust
system of parallel and redundant operation for customers who
require high availability. The device provides synchronization,
prebias startup, and conditional overvoltage techniques to
identify and safely shut down an erroneous power supply in
parallel operation mode.
The ADP1050 is based on flexible state machine architecture
and is programmed using an intuitive graphical user interface
(GUI). The easy to use GUI reduces design cycle time and
results in a robust, hardware coded system loaded into the built-
in EEPROM. The small size (4 mm × 4 mm) of the LFCSP
package makes the ADP1050 ideal for ultracompact, isolated
dc-to-dc power module or embedded power designs.
