WARNING AND LEGAL TERMS AND CONDITIONS.Rev. 0 | Page 1 of 8

FEATURES

ADP1053 daughter card with 40-pin connector

and I2C interface

Plugs into ADP1053 evaluation motherboard

PMBus compliant

Low component count

PCB size: 28 mm × 50 mm

Robust design

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.

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-I2C dongle interface between the

daughter card and a PC running Windows® 2000, Windows NT,

Windows XP, Windows Vista®, or Windows 7.

The USB-to-I2C dongle interface (Part No. ADP-I2C-USB-Z)

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).

10612-002

Figure 2. Backside of the Daughter Card

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-I2C 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.
