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-I
2
C dongle interface between the
daughter card and a PC running Windows® 2000, Windows NT,
Windows XP, Windows Vista®, or Windows 7.
The USB-to-I
2
C 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.
