ADI DC2820A-B Quad 3A Silent Switcher μModule Regulator Evaluation Board With Package-Level EMI Shield

Shenzhen Mingjiada Electronics Co., Ltd., a renowned distributor of electronic components, is now officially supplying the ADI DC2820A-B evaluation board. At the heart of this board is the LTM8060F quad-output high-performance Silent Switcher® μModule® buck regulator. Its unique package-level EMI shielding and compact design provide engineers with a turnkey solution for addressing complex power supply noise and space constraints.

【Core Analysis: DC2820A-B Evaluation Board and LTM8060F μModule Regulator】

The DC2820A-B evaluation board serves as a hardware platform for assessing and developing power systems based on the LTM8060F chip. Its core value lies in integrating ADI's advanced Silent Switcher architecture with μModule packaging technology, condensing complex multi-output power circuits into a single miniature module.

1. Revolutionary Silent Switcher® Architecture and EMI Shielding

The LTM8060F's standout feature is its patented Silent Switcher architecture. This technology significantly reduces high-frequency electromagnetic noise generated by fast switching operations at its source by optimizing internal switch node layout and current paths. This enables the regulator to easily meet stringent international EMC standards like CISPR 22 Class B without requiring bulky additional input filters. This capability is critical for applications in noise-sensitive environments such as medical imaging equipment, RF communication base stations, and precision test instruments.

Further innovation lies in its package-level EMI shielding. The LTM8060F utilizes a specialized pre-soldered grid array (PSGA) package measuring just 16mm × 11.9mm × 2.9mm. This package incorporates an internal metal shielding layer, effectively creating a miniature “Faraday cage” around the chip. This design efficiently isolates and absorbs radiated noise generated within the module, preventing interference with external sensitive circuits. This physical EMI protection at the package level offers more comprehensive and space-saving shielding compared to traditional external shielding solutions.

2. High-Performance, Flexible Power Output

The DC2820A-B evaluation board demonstrates the LTM8060F's robust electrical performance:

Wide Input Range: Supports a broad operating input voltage from 5.4V to 40V, compatible with common 12V and 24V industrial buses and battery-powered systems.

Four Independent Outputs: On-board outputs are preset to 5V, 3.3V, 1.5V, and 1.2V, covering power requirements for most chips including processors, memory, FPGAs, and analog circuits.

High Current & Programmability: Each output delivers up to 3A continuous current. Output voltage is flexibly adjustable from 0.8V to 8V via simple external resistor programming to meet custom requirements.

Scalability: Supports phase-parallel operation, enabling multiple outputs to be connected in parallel for higher current demands on a single rail, offering exceptional design flexibility.

【DC2820A-B Application Scenarios】

With ultra-low noise, high integration, and high reliability, the DC2820A-B evaluation board and the LTM8060F solution it represents are ideal for the following critical applications:

Communications Infrastructure (5G): The DC2820A-B delivers clean, stable power to RF transceivers, data converters, and field-programmable gate arrays (FPGAs) in base stations, ensuring signal integrity.

Aerospace & Defense: DC2820A-B enables high-efficiency, low-radiation power management in space-constrained, harsh-environment airborne or command systems.

Instrumentation & Measurement: DC2820A-B serves high-precision oscilloscopes, spectrum analyzers, and similar equipment, where its low-noise characteristics are fundamental to measurement accuracy.

Medical Electronics: The DC2820A-B powers medical imaging equipment (e.g., portable ultrasound) and clinical monitors, preventing power supply noise from interfering with sensitive physiological signal acquisition.

Industrial Automation: Within complex industrial control and robotic systems, the DC2820A-B delivers compact, reliable multi-channel power to diverse core chips.
