Three-Channel Digital Power Supply Controller

Product Details

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 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.

All eight PWM outputs can also be assigned to enable a singlechannel solution, which may be required in high power, high efficiency applications.

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).

EVAL-ADP1053 Circuit Diagram

Product Details

The ADP1053 daughter card evaluation board allows the user to quickly evaluate the ADP1053. 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.

The user guide UG-388 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.
