GENERAL DESCRIPTION

The ADP1053, based on a voltage mode PWM architecture, is
a flexible, application dedicated digital controller designed for
isolated and nonisolated dc-to-dc power supply applications.
The ADP1053 enables highly efficient power supply design and
facilitates the introduction of intelligent power management
techniques to improve energy efficiency at a system level. The

ADP1053 operates from a single 3.3 V supply.

The ADP1053 provides control, monitoring, and protection
of up to three independent channel outputs. The eight flexible
PWM outputs can be configured as three independent channels:
two regulated channels with feedback control plus one additional
unregulated channel with a fixed duty cycle. The frequency of
these three channels can be programmed individually from
50 kHz to 625 kHz; all channels can be synchronized internally
or to an external signal.

ADP1053DC-EVALZ DAUGHTER CARD EVALUATION BOARD

Features include differential voltage sensing, fast current sensing,
flexible start-up sequencing and tracking, and synchronization
between devices to reduce low frequency system noise. Protection
and monitoring features include overcurrent protection (OCP),
undervoltage protection (UVP), overvoltage protection (OVP),
and overtemperature protection (OTP).

EVALUATION BOARD DESCRIPTION

The ADP1053 daughter card evaluation board allows the user
to quickly evaluate the ADP1053 (see Figure 1). The ADP1053
daughter card plugs into an existing ADP1053 evaluation
motherboard. Communication to the daughter card is established
by connecting the USB-to-I
daughter card and a PC running Windows® 2000, Windows NT,
Windows XP, Windows Vista®, or Windows 7.

The USB-to-I

must be purchased separately from Analog Devices, Inc. The
graphical user interface (GUI) software for the ADP1053
daughter card evaluation board can be downloaded from the

ADP1053 product page.

This user guide describes how to set up and use the ADP1053
daughter card evaluation board. The user guide should be read
in conjunction with the ADP1053 data sheet, which provides
detailed information about the ADP1053 3-channel digital
power supply controller.

HARDWARE DESCRIPTION

40-PIN CONNECTOR

The ADP1053 daughter card PCB is 28 mm × 50 mm. A
40-pin connector is soldered to the back of the daughter
card evaluation board (see Figure 2).

USB-TO-I2C DONGLE

For a complete evaluation of the ADP1053, the following items
are required:

• ADP1053 evaluation motherboard

• ADP1053 evaluation daughter card

• USB-to-I

• Software GUI

Figure 4 shows how to use the USB-to-I
the ADP1053 daughter card to the PC.

C dongle interface

C dongle to connect

The 40-pin connector plugs directly into an existing ADP1053
evaluation motherboard. A 5 V source from the USB connection
provides power to the on-board ADP3303 LDO, which, in turn,
provides the 3.3 V power to the ADP1053.

Figure 3 shows the pin assignments for the 40-pin connector on
the ADP1053 daughter card evaluation board.

OPERATING INSTRUCTIONS FOR THE EVALUATION BOARD

To use the ADP1053 evaluation board, follow these steps:

1. Insert the ADP1053DC-EVALZ daughter card into the

ADP1053 evaluation motherboard (see Figure 5). Note

that users must create a motherboard for the ADP1053
evaluation daughter card (the motherboard shown in
Figure 5 is a prototype).

2. Connect the cables of the USB-to-I

2

C dongle to the daughter

card and to the PC (see Figure 4).

The USB interface provides the 5 V supply to the daughter
card. The daughter card has an on-board LDO (the ADP3303)
that provides the 3.3 V power to the ADP1053.

3. Download the ADP1053 GUI software from the ADP1053

product page and install the software on a PC.

4. Run the GUI software to verify the connection to the

ADP1053 before applying the input supply voltage to

the motherboard.

5. Apply power to the input terminals of the motherboard.
