STMicroelectronics STEVAL-SPDC01V2

Overview

STEVAL-SPDC01V2 from STMicroelectronics is a demonstration board for the SPDC12L00010 10 A high-density DC-DC PoL module, implementing a complete step-down power supply with integrated controller, FETs, inductor, and support components in a 15 × 15 mm LGA package; supports 1.8–14 V input, 0.6–5 V adjustable output, 93% peak efficiency, and operates from –40 °C to +85 °C.

For engineers reviewing the STEVAL-SPDC01V2 datasheet, STEVAL-SPDC01V2 pinout, STEVAL-SPDC01V2 application, or STEVAL-SPDC01V2 equivalent, this board enables rapid evaluation of the SPDC12L00010 module's pre-bias startup, programmable Power Good delay, master/slave synchronization, selectable UVLO (5 V/12 V), and source/sink capability in space-constrained industrial and embedded power designs.

Technical Context

The STEVAL-SPDC01V2 implements fixed-frequency voltage-mode control with adjustable switching frequency and soft-start/inhibit logic to ensure controlled power-up under varying load conditions. It validates the SPDC12L00010's integrated thermal shutdown, overvoltage protection (latched or non-latched), and 180° phase-shifted synchronization for multi-module current sharing.

This board demonstrates the module's ability to operate without external heatsink or airflow while delivering 10 A continuous output at up to 93% efficiency, enabled by synchronous rectification and thermally enhanced LGA packaging with exposed thermal pad connected to PGND.

FAQ

What is the primary function of the STEVAL-SPDC01V2 board?

The STEVAL-SPDC01V2 is a demonstration board designed exclusively to evaluate the SPDC12L00010 10 A integrated DC-DC PoL module. It provides all necessary circuitry-including input/output filtering, feedback network, synchronization interface, and Power Good signaling-to validate performance under real-world load, thermal, and dynamic conditions without requiring additional design effort.

Does STEVAL-SPDC01V2 support adjustable output voltage?

Yes, the board supports adjustable output voltage down to 0.6 V using the FB (feedback) pin and an external resistor divider. The reference schematic shows R8 and R7 as configurable components for setting VOUT; no hardware modification is needed beyond populating appropriate resistors per target voltage.

Can STEVAL-SPDC01V2 be used for synchronized multi-phase operation?

Yes, it supports master/slave synchronization with 180° phase shift via the SYNC pin (L5). When configured as slave, the board accepts an external clock signal to align switching edges, enabling interleaved operation with another STEVAL-SPDC01V2 or compatible SPDC-based board to reduce input/output ripple and improve thermal distribution.

Is pre-bias startup supported on this evaluation board?

Yes, pre-bias startup is fully implemented and validated on STEVAL-SPDC01V2. The SPDC12L00010 module monitors output voltage during startup and delays gate drive activation until VOUT falls below the programmed threshold, preventing reverse current flow into a pre-charged rail-critical for hot-swap and redundant power systems.
