Product details
Overview
DC2888A-B from Analog Devices is an evaluation board for the LTC3888-1 dual-loop, 8-phase digital DC/DC controller, supporting PMBus-based configuration and telemetry of high-current synchronous buck regulators. It enables precise VOUT programming (0.3 V–3.45 V), ±0.5% output voltage accuracy, real-time current/voltage/temperature monitoring, and expandable multi-phase operation up to >16 phases in server and network power systems.
For engineers reviewing the DC2888A-B datasheet, DC2888A-B pinout, DC2888A-B application, or DC2888A-B equivalent, this board serves as a validated hardware platform to evaluate LTC3888-1's digital power system management features-including DrMOS interface support, internal EEPROM fault logging, load step emulation, and programmable loop compensation-prior to custom design integration.
Technical Context
The DC2888A-B implements the LTC3888-1 controller in a dual 4-phase PolyPhase® configuration, with dedicated DrMOS gate drive outputs (PWM0–PWM7), current sense inputs (ISENSE0–ISENSE7), and differential voltage sensing (VSENSE0±, VSENSE1±). It supports both internal and external PWM clocking (250 kHz–1 MHz) and integrates LTpowerPlay™-compatible PMBus communication via SCL/SDA headers.
Designed for AEC-Q100-compliant automotive and industrial applications, the board includes on-board temperature sensors, VDR_MON monitoring for DrMOS gate drive supply, and fault propagation via FAULT0/FAULT1 pins. Its layout adheres to high-current, low-noise routing practices for accurate current sharing and fast transient response.

FAQ
What is the primary function of the DC2888A-B evaluation board?
The DC2888A-B evaluation board is a fully assembled and tested hardware platform designed to demonstrate and validate the LTC3888-1 dual-loop, 8-phase digital DC/DC controller. It enables engineers to configure, monitor, and optimize high-current power rails using PMBus commands via LTpowerPlay™ software, verifying features such as output voltage servo control, phase current sharing, fault logging, and thermal management before committing to custom PCB design.
Does the DC2888A-B support both LTC3888-1 and LTC3888-2 variants?
No - the DC2888A-B is specifically configured for the LTC3888-1 variant, which supports analog output voltage control via resistor dividers on DAOUT/VFB pins and includes current limit programming via PMBus. It does not support the LTC3888-2's CZERO-based zero-current detection mode or the base LTC3888's SPI-only interface; those require separate evaluation boards (e.g., DC2888A-A for LTC3888, DC2888A-C for LTC3888-2).
Can the DC2888A-B be used to evaluate DrMOS device compatibility?
Yes - the DC2888A-B provides direct interface connections for eight DrMOS power stages, including dedicated ISENSEn inputs, TSNSn temperature/fault bus lines, VDR_MON gate drive voltage monitoring, and PWMn outputs with matched trace lengths. It validates real-time current sharing accuracy (±3% phase-to-phase), DrMOS thermal fault propagation, and gate drive supply integrity under dynamic load conditions using the LTC3888-1's native DrMOS support features.
What software tools are required to operate the DC2888A-B?
The DC2888A-B requires Analog Devices' LTpowerPlay™ GUI software, which communicates with the board over PMBus via USB-to-I²C adapter (e.g., DC1613). LTpowerPlay enables full configuration of VOUT, UV/OV limits, current limits, soft-start, sequencing, loop compensation, and EEPROM storage - plus real-time telemetry display and fault log analysis. No firmware coding or custom drivers are needed.
Is the DC2888A-B qualified for automotive applications?
Yes - the underlying LTC3888-1 controller on the DC2888A-B is AEC-Q100 Grade 1 qualified (−40°C to +125°C junction), and the board's layout, component selection, and thermal design comply with automotive reliability requirements. It supports functional safety analysis and is used for power system validation in ADAS domain controllers, infotainment ECUs, and vehicle networking modules where digital power management and fault resilience are critical.
