Product details
Overview
DC1040A-A from Analog Devices (formerly Linear Technology) is a demonstration circuit board implementing the LTC3544 quad synchronous step-down DC/DC converter IC. It delivers four independent regulated outputs (1.2V/100mA, 1.5V/200mA, 0.8V/200mA, 1.8V/300mA) from a 2.25V–5.5V input, operates at 2.25MHz switching frequency, and achieves >90% efficiency for battery-powered portable electronics evaluation.
For engineers reviewing the DC1040A-A datasheet, DC1040A-A pinout, DC1040A-A application, or DC1040A-A equivalent, this page provides verified board-level specifications, thermal design context, output ripple performance under load, RUN-controlled enable sequencing, and alternative evaluation platforms compatible with LTC3544-based quad buck regulation.
Technical Context
DC1040A-A implements the LTC3544EUD or LTC3544BEUD in a fully assembled, tested 16-pin QFN evaluation platform with exposed thermal pad. Each of the four buck regulators features independent RUN control, pulse-skipping mode at light loads to maintain low ripple, and internal compensation eliminating external loop components.
The board supports both burst-mode (LTC3544EUD) and pulse-skip-mode (LTC3544BEUD) variants via PCB labeling and jumper configuration (JP1–JP4). Input voltage ringing mitigation is addressed via optional tantalum capacitor pads on the bottom side for long-lead lab testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.25V to 5.5V - Supports single-cell Li-ion, Li-polymer, and dual-cell alkaline/NiMH battery inputs without pre-regulation. |
| Output Voltages | VOUT1 = 1.2V ±2%, VOUT2 = 1.5V ±2%, VOUT3 = 0.8V ±2%, VOUT4 = 1.8V ±2% - Pre-set for common core/logic/I/O rail sequencing in portable SoC designs. |
| Max Output Currents | 100mA (VOUT1), 200mA (VOUT2 & VOUT3), 300mA (VOUT4) - Matches typical current demands of RF transceivers, sensors, microcontrollers, and memory interfaces. |
| Switching Frequency | 2.25MHz - Enables use of compact 1µH inductors and 10µF ceramic capacitors; avoids audible noise and simplifies EMI filtering. |
| Output Ripple | <15mVP–P (20MHz BW) across all outputs at full load - Measured directly at VOUT/GND terminals; validates low-noise power delivery for sensitive analog circuits. |
| Quiescent Current | <1µA total in shutdown - Confirmed with all RUN pins de-asserted; enables ultra-low-power system sleep states. |
| Efficiency | >90% typical - Achieved across mid-load range (30–80% of max current); reduces thermal load in sealed handheld enclosures. |

FAQ
What is the primary function of the DC1040A-A demonstration circuit?
The DC1040A-A demonstration circuit implements the LTC3544 quad synchronous buck regulator to provide four independently controlled, pre-configured DC output rails. It serves as a ready-to-use hardware platform for evaluating voltage regulation accuracy, load transient response, efficiency, and thermal behavior-without requiring custom PCB design or component selection. The DC1040A-A is not a standalone IC but a fully assembled evaluation board.
Which LTC3544 variants are supported on the DC1040A-A board?
The DC1040A-A board supports both the LTC3544EUD (burst-mode operation) and LTC3544BEUD (pulse-skip mode) versions. The installed controller is identified by label on the PCB, and jumper shunts JP1–JP4 allow individual RUN control for each regulator. No hardware modification is needed to evaluate either variant-only firmware or test setup changes affect operational mode.
How is output voltage accuracy verified on the DC1040A-A?
Output voltage accuracy on the DC1040A-A is verified per Table 1 of the Quick Start Guide: all four outputs must remain within ±2% tolerance across the full input range (2.25V–5.5V) and respective load ranges (0–100mA for VOUT1, 0–200mA for VOUT2/VOUT3, 0–300mA for VOUT4). Measurements are taken directly at the VOUT/GND terminals using proper oscilloscope probe technique to avoid ground lead artifacts.
Does the DC1040A-A require external compensation components?
No, the DC1040A-A does not require external compensation components. The underlying LTC3544 IC integrates full internal compensation circuitry, and the DC1040A-A board layout preserves this feature. This eliminates the need for external Type-II or Type-III compensation networks, reducing design complexity and board area-critical for rapid prototyping and space-constrained applications using the DC1040A-A.
What thermal management provisions are included on the DC1040A-A?
The DC1040A-A board incorporates thermal design aligned with the LTC3544's 16-pin QFN package, including an exposed thermal pad soldered to a large copper pour on the PCB bottom layer. This structure enables efficient heat conduction from the IC die to the board plane. The DC1040A-A documentation confirms that this layout supports >90% efficiency and low thermal rise during continuous full-load operation across all four channels.
