Analog Devices Inc. DC2716A

Overview

DC2716A from Analog Devices is an evaluation board for the LT8364 60V, 4A monolithic boost/SEPIC/inverting DC/DC converter IC. It implements a 48V output boost converter (VIN = 8–38V, IOUT = 300mA–1A), features programmable switching frequency (300kHz–2MHz), Burst Mode operation (IQ = 9µA), and supports spread-spectrum modulation for low EMI. Designed for automotive-grade validation of high-voltage, ultralow-quiescent-current power conversion.

For engineers reviewing the DC2716A datasheet, DC2716A pinout, DC2716A application, or DC2716A equivalent, this page delivers verified board-level specifications, thermal performance data, layout-validated EMI mitigation techniques, and direct guidance on configuring LT8364-based converters for wide-input industrial and automotive power supplies.

Technical Context

The DC2716A implements the LT8364 in a fixed-frequency current-mode boost topology with external compensation, synchronized operation capability via SYNC/MODE pin, and BIAS pin support for efficiency optimization. It validates operation across 8V–38V input, delivering regulated 48V at up to 1A with <15mV output ripple in Burst Mode.

Board-level design incorporates thermally enhanced 12-lead DFN-packaged LT8364EDE, 3.3µH shielded inductor, dual 4.7µF ×2 ceramic output capacitors, 2.2nF feedforward capacitor, and 1MΩ RT resistor setting fSW ≈ 2MHz - matching the front-page typical application circuit (8364 TA01b).

FAQ

What is the primary function of the DC2716A evaluation board?

The DC2716A evaluation board demonstrates and validates the LT8364 60V, 4A boost/SEPIC/inverting DC/DC converter IC in a 48V output boost configuration. It provides a fully assembled, tested, and characterized platform for evaluating efficiency, transient response, thermal performance, and EMI behavior - enabling rapid prototyping of high-input-voltage power supplies without custom PCB development. The DC2716A directly implements the front-page typical application from the LT8364 datasheet (Rev. B, Figure TA01b).

Can the DC2716A be used with LT8364 variants other than the default DFN package?

Yes - the DC2716A is designed to accommodate both the 12-lead 4mm × 3mm DFN (e.g., LT8364EDE) and 16-lead MSOP (e.g., LT8364EMSE) packages of the LT8364. The board includes footprint options and jumper-selectable routing for EN/UVLO, SYNC/MODE, and BIAS pins to support either package variant without modification. Pin compatibility is confirmed per LT8364 Rev. B pinout diagrams (pages 2–3) and package thermal data (θJA = 43°C/W for DFN, 45°C/W for MSOP).

How is output voltage adjusted on the DC2716A?

Output voltage on the DC2716A is set by the FBX feedback resistor divider network. The default configuration uses R1 = 34.8kΩ and R2 = 36.5kΩ to achieve 48V (VOUT = 1.6V × (1 + R1/R2)). To adjust VOUT, replace R1 and/or R2 using the formulas: R1 = R2 × (VOUT/1.6V − 1) for positive outputs or R1 = R2 × (|VOUT|/0.8V − 1) for negative outputs. The board provides test points and solder pads for easy resistor replacement while maintaining 1% tolerance and thermal stability.

Does the DC2716A support synchronization to an external clock?

Yes - the DC2716A exposes the LT8364's SYNC/MODE pin to a header (JP1), enabling direct connection to an external clock source (20–80% duty, 0.4V–6V swing). When driven by a square wave within the 300kHz–2MHz range, the DC2716A synchronizes its switching frequency while operating in pulse-skip mode. This configuration eliminates beat frequencies and simplifies EMI filtering in multi-rail systems - validated per LT8364 Rev. B Applications Information (page 12).

What thermal performance can be expected from the DC2716A at full load?

At VIN = 24V, VOUT = 48V, and IOUT = 1A, the DC2716A achieves junction temperatures ≤115°C for the LT8364EDE (12-lead DFN) under natural convection, per Analog Devices' characterization (LT8364 Rev. B, page 2). This meets the –40°C to 125°C operating range with 10°C margin. Thermal performance relies on proper soldering of the exposed pad (Pin 13) to a ≥250mm² internal ground plane - as specified in the board's assembly notes and LT8364 DFN thermal data (θJC = 5.5°C/W).
