Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Daughter Card Evaluation Board for the ADP1053 Digital Power Supply Controller Features include differential voltage sensing, fast current sensing, FEATURES flexible start-up sequencing and tracking, and synchronization ADP1053 daughter card with 40-pin connector between devices to reduce low frequency system noise. Protection 2 and I C interface and monitoring features include overcurrent protection (OCP), Plugs into ADP1053 evaluation motherboard undervoltage protection (UVP), overvoltage protection (OVP), PMBus compliant and overtemperature protection (OTP). Low component count PCB size: 28 mm 50 mm EVALUATION BOARD DESCRIPTION Robust design The ADP1053 daughter card evaluation board allows the user to quickly evaluate the ADP1053 (see Figure 1). The ADP1053 GENERAL DESCRIPTION daughter card plugs into an existing ADP1053 evaluation The ADP1053, based on a voltage mode PWM architecture, is motherboard. Communication to the daughter card is established a flexible, application dedicated digital controller designed for 2 by connecting the USB-to-I C dongle interface between the isolated and nonisolated dc-to-dc power supply applications. daughter card and a PC running Windows 2000, Windows NT, The ADP1053 enables highly efficient power supply design and Windows XP, Windows Vista, or Windows 7. facilitates the introduction of intelligent power management 2 techniques to improve energy efficiency at a system level. The The USB-to-I C dongle interface (Part No. ADP-I2C-USB-Z) must be purchased separately from Analog Devices, Inc. The ADP1053 operates from a single 3.3 V supply. graphical user interface (GUI) software for the ADP1053 The ADP1053 provides control, monitoring, and protection daughter card evaluation board can be downloaded from the of up to three independent channel outputs. The eight flexible ADP1053 product page. PWM outputs can be configured as three independent channels: two regulated channels with feedback control plus one additional This user guide describes how to set up and use the ADP1053 unregulated channel with a fixed duty cycle. The frequency of daughter card evaluation board. The user guide should be read these three channels can be programmed individually from in conjunction with the ADP1053 data sheet, which provides 50 kHz to 625 kHz all channels can be synchronized internally detailed information about the ADP1053 3-channel digital power supply controller. or to an external signal.
