The main function of controlling the output voltage is performed
using the feedback ADCs, the digital loop filter, and the PWM
block.
The feedback ADCs use a multipath approach (patent pending).
The
coarse) ADC with a low speed, high resolution (slow and accurate)
ADC. Loop compensation is implemented using the digital filter.
This proportional, integral, derivative (PID) filter is implemented
in the digital domain to allow easy programming of filter char-
acteristics, which is of great value in customizing and debugging
designs.

The PWM block generates up to seven programmable PWM
outputs for control of FET drivers and synchronous rectification
FET drivers. This programmability allows many traditional and
unique switching topologies to be realized.
A current share bus interface is provided for paralleling multiple
power supplies. The
and control for N + 1 redundant power supplies.
Conventional power supply housekeeping features, such as remote
and local voltage sense and primary and secondary side current
sense, are included. An extensive set of protections is offered,
including overvoltage protection (OVP), overcurrent protection
(OCP), overtemperature protection (OTP), undervoltage protec-
tion (UVP), ground continuity monitoring (voltage continuity),
and ac sense.
All these features are programmable through the I
face. This bus interface is also used to calibrate the power supply.
Other information that is useful for power monitoring, such as
input current, output current, and fault flags, is also available
through the I
The internal EEPROM can store all programmed values and
allows standalone control without a microcontroller. A free,
downloadable GUI is available and provides all the necessary
software to program the ADP1046. To obtain the latest software
