ADP1043A
The ADP1043A is a secondary side controller for switch mode
power supplies (SMPS). It is designed for use in isolated redun-
dant applications. The ADP1043A integrates the typical functions
that are needed to control a power supply. These include
A current share bus interface provides for parallel power supplies.
The part also has hot-swap OrFET sense and control for N + 1
redundant power supplies.
Conventional power supply housekeeping features, such as remote

Housekeeping and I 2 C interface
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, and ac sense.
All these features are programmable through the I 2 C bus inter-
face. This bus interface is also used to calibrate the power supply.
? Calibration and trimming
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 ADP1043A combines a high speed, low resolution
(fast and coarse) ADC and a low speed, high resolution (slow and
accurate) ADC. Loop compensation is implemented using the
digital filter. This PID (proportional, integral, derivative) filter is
implemented in the digital domain to allow easy programming
of filter characteristics, which is of great value in customizing
Other information, such as input current, output current, and
fault flags, is also available through the I 2 C bus interface.
The internal EEPROM can store all programmed values and
allows standalone control without a microcontroller. A free,
downloadable GUI is available that provides all the necessary
software to program the ADP1043A. For more information
about the GUI, contact Analog Devices, Inc., for the latest
software and a user guide.
The ADP1043A operates from a single 3.3 V supply and is
specified from ?40°C to +85°C.
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.
