TOPOLOGY AND CIRCUIT DESCRIPTION
This evaluation board features the ADP1048 in a typical AC/DC switching power supply in a bridgeless boost power factor
correction (PFC) topology. The circuit is designed to provide a rated load of 385V/300W from an AC input voltage source of 90
VRMS to 265 VRMS AC. The ADP1048 provides functions all the functions necessary for active PFC circuit plus accurate AC
power metering. It achieves near-unity power factor, low distortion of the input current, the output voltage regulation, over
current protection, AC line fault detection and protection, over temperature protection, and power supply shutdown. It also can
optimize light load efficiency performance using output voltage adjustment and frequency reduction.
Please refer to the appendix for the detailed schematic. The AC input side consists of the input terminals, EMI filter, inrush
relay and its control circuit. The D4 is used for input voltage sensing. The D21 is used to charge the output capacitor during the
initial stage. It has two boost circuits, one consists of L3, Q2 and D15, while the other consists of L2,Q1 and D2. The D34 and
D35 are slow recovery diodes. The boost circuit consists boost inductor (L2), boost switch (Q1) and diode (D2). The gate
signal for the boost switch comes from the ADP1048 through the ADP3634 gate driver. The ADP1048 (U1, on daughter card)
can be powered either via the USB 5V via an ADP3303 LDO (U2, on daughter card) present on the same daughter card, or
via the auxiliary power supply on the board. Thermistor (RTD1) is placed close to the MOSFET on the board allowing over
temperature protection functionality to be implemented.

Figure 3 - ADP1048 and GUI interaction
The register settings (having extension .48r) and the board settings (having extension .48b) are two files that are associated
with the ADP1048 software. The register settings file contains information that govern the functionality of the part such as the
over voltage and over current limits, softstart timing, PWM settings etc. The ADP1048 stores all its settings in the EEPROM.
When the ADP1048 is connected to the USB adapter the LDO powers the I.C. and the GUI downloads the settings from the
registers of the ADP1048 so that the state of the part is known. It is possible to save these settings in a file for later use. Older
register settings are overwritten when new files are loaded.
The EEPROM on the ADP1048 can contain the information about the board, such as current sense resistor, output inductor
and capacitor values. This information is also stored in board setup file (extension .48b) and is necessary for the GUI to
display the correct information in the ‘Monitor’ tab as well as ‘Filter Settings’ window. Always make sure that the correct board
file has been loaded for the board currently in use.
Each ADP1048 chip has trim registers for the temperature, input current and the output voltage and input voltage. These can
be configured during production and are not overwritten whenever a new register settings file is loaded. This is done in order
to retain the trimming of all the ADCs for that corresponding environmental and circuit condition (component tolerances,
thermal drift, etc.).

SETUP
NOTE: DO NOT CONNECT THE USB CABLE TO THE EVALUATION BOARD UNTIL THE SOFTWARE HAS
FINISHED INSTALLING
1)
Install the ADP1048 software by inserting the installation CD. The software setup will start automatically and a guided
process will install the software as well as the USB drivers for communication of the GUI with the IC using the USB
adapter.
2)
Insert the daughter card in connector J6 as shown in Figure 4.
3)
Ensure that the PS_ON switch (SW1 on schematic) is turned to the on position. It is located on the bottom left half of the
board (Figure 4).
4)
Connect the evaluation board to the USB port on the PC using the “USB to I2C interface” adapter as shown in Error!
Reference source not found.1.
5)
The software should report that the ADP1048 has been located on the board. Click “Finish” to proceed to the Main
Software Interface Window. The serial number reported on the side of the checkbox indicates the USB adapter serial
number. The windows also displays the device I2C address.
Figure 6 - ADP1048 address in the GUI
6)
If the software does not detect the part it enters into simulation mode. Ensure that the connector is connected to J8/J11
(on main board) Click on ‘Scan for ADP1048A now’ icon (magnifying glass) located on the top right hand corner of the
screen.
Figure 7 - “Scan for ADP1048 Now’ icon
7)
The board setting is store in the IC and this step is optional. Click on the “Load Board Settings” icon (fourth button
from the left) and select the ADI1048bridgelessPFC.48b file. This file contains all the board information including values of
shunt and voltage dividers. Note: All board setting files have an extension of .48b
Figure 8 - Different icons on dashboard for loading and saving .48r and .48b files
8)
The IC on the evaluation board comes preprogrammed and this step is optional. The original register configuration
is stored in the ADP1048bridgelessPFC.48r register file. Note: All register files have an extension of .48r. The file can be
loaded using the second icon from the left in Figure .

9)
PRD 1378
Connect a resistive or electronic load to the output connections of Vout+ and Vout-. Note that the load should be
connected before the input power is supplied to the evaluation board for safety concerns.
10) Connect a 50 or 60 Hz isolated ac power source, which has to be turned off, to ac plug J1 or terminals J9 and J10.
11) Turn on AC power source and increase the input voltage within the range from 85Vrms to 265Vrms.
12) The evaluation board should now up and running, and ready for evaluation. The output should now read about 385 VDC.
13) Click on the ‘MONITOR’ tab and then on the Flags and readings icon. This window provides a snapshot of the entire state
of the PSU in a single user friendly window.
Figure 9 - Monitor window in GUI
During power up, the ADP1048 is connected to the USB port (5V) and the LDO powers the IC. It takes 20µsec for VCORE (pin
26) to reach an internal voltage of 2.5V. After this, the I.C. downloads the contents of the registers into the EEPROM. After this
the softstart ramp begins.
After successful startup and in steady state condition, 5 LEDs on the board to provide to the user the status of the board. All
the LEDs will be turned ON indicating that there are no faults detected such as over voltage or over current. In case of a fault
the PGOOD or AC_OK LEDs will be turned OFF indicating that some flag has tripped due to an out of bounds condition. The
monitor window will display the appropriate state of the PSU.

ADP1048 PROGRAMMING SOFTWARE
The goal of this evaluation kit is to allow the user to get an insight into the flexibility offered by the extensive programming
options offered by the ADP1048. Several test points on the board allow easy monitoring of the various signals. The user can
also use the software to program multiple responses (such as disable power supply or disable the PWM) for various fault
conditions. There are several main windows where the user can use to program and evaluate the PSU. They can be
accessed from the Setup window in the GUI. The ADP1048 can be easily programmed to modify the behavior of the PSU
under different fault and load conditions without any hardware changes. All the changes are purely through software and do
not require desoldering components and replacing them with new values to specify a different operating condition.
