Product details
Overview
SPDC12L00010 from STMicroelectronics is a fully integrated 10 A step-down DC-DC converter module in LGA package, delivering 0.6–5 V output from 1.8–14 V input with 93% peak efficiency and 40 mVpp output ripple. It integrates controller, power FETs, inductor, and support components, enabling standalone point-of-load regulation in space-constrained server and telecom systems.
For engineers reviewing the SPDC12L00010 datasheet, SPDC12L00010 pinout, SPDC12L00010 application, or SPDC12L00010 equivalent, key selection criteria include its programmable soft-start, master/slave synchronization with 180° phase shift, selectable UVLO (5 V/12 V), pre-bias start-up, and Power Good with programmable delay - all critical for high-density distributed power architectures.
Technical Context
The SPDC12L00010 employs fixed-frequency voltage-mode control with internal 0.6 V reference (±1% tolerance) and synchronous rectification to achieve ultrafast transient response and stable regulation down to 0.6 V. Its integrated oscillator supports frequency adjustment via external resistor on OS pin and enables precise inter-module synchronization via SYNC pin.
Protection architecture includes latched or non-latched overvoltage protection (OVP), cycle-by-cycle overcurrent limiting (12 A trip), thermal shutdown at 120 °C case temperature, and programmable undervoltage lockout (UVLO) thresholds - all implemented without external components beyond PGDLY capacitor and SS_INL timing capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 10 A continuous; supports full load without heatsink or airflow in free-air conditions on 4-layer PCB |
| Input voltage range | 1.8 V to 14 V; dual-supply architecture allows separate VCC (4.5–14 V) and VIN rails |
| Output voltage range | 0.6 V to 5 V; programmed via FB pin with ±1% regulation accuracy over -40 °C to +85 °C |
| Peak efficiency | 93%; achieved at mid-load with 12 V input and 3.3 V/5 V output, minimizing thermal stress |
| Output ripple | 40 mVpp; measured at 12 V input, 10 A load, 2×330 μF output capacitance, 20 MHz BW |
| Switching frequency | 678–780 kHz; factory-trimmed, adjustable ±15% via OS pin resistor |
| Thermal shutdown | 120 °C at center of top case (T1); de-rates output current progressively above 75 °C ambient |
Pinout & Package
SPDC12L00010 uses a thermally enhanced 15 mm × 15 mm × 3 mm over-molded Land Grid Array (LGA) package with exposed thermal pad (PH bank) for bottom-side heat dissipation. The package is RoHS-compliant and designed for standard SMT reflow assembly, including back-side mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Bank 1) | Primary power input | Accepts 1.8–14 V DC; must be decoupled per Section 5.18; supplies power stage only |
| VCC (L3) | Controller supply | 4.5–14 V rail for internal logic; can be tied to VIN if ≥4.5 V, otherwise requires separate supply |
| VOUT (Bank 3) | Regulated output | Delivers 0.6–5 V at up to 10 A; low-impedance path required per Section 5.19 |
| FB (L9) | Feedback sense | Inverting input of error amplifier; sets output voltage via external resistor divider referenced to 0.6 V |
| SS_INL (L11) | Soft-start/inhibit | Pull <0.5 V to disable; external capacitor sets soft-start ramp time (e.g., 3.3 nF ≈ 10 ms total) |
| PG (L4) | Power Good indicator | Open-collector output pulled low if VOUT deviates >±10% from target; 10 kΩ pull-up to VAUX |
| PGDLY (L5) | PG delay control | Capacitor-to-SGND sets rising-edge delay: PGdelay = 0.5 × CPGDLY (pF) in μs |
| SYNC (L6) | Frequency synchronization | Master/slave interface; enables 180° phase shift between modules when tied together |
| PRG (L7) | Multi-function configuration | Selects UVLO threshold (5 V/12 V bus), OVP latch mode, and post-soft-start sink capability |
| VAUX (J11) | Auxiliary 5 V supply | Internally regulated 4.5–5.5 V source for PRG/OS biasing; no external capacitor needed |
Key Features
| Feature | Design Value |
|---|---|
| Integrated power train | Combines controller, MOSFETs, shielded inductor, and compensation in single LGA module - eliminates 30+ discrete components |
| Pre-bias start-up | Enables safe turn-on into pre-charged output capacitors without reverse current or voltage overshoot |
| Programmable Power Good delay | Adjustable rising-edge delay (0–100 μs typical) avoids false PG assertion during output voltage ramp |
| Source/sink capability | Selectable post-soft-start current sink mode improves transient response under sudden load removal |
| Thermal de-rating table | Published derating curves per VOUT (0.7–5.0 V) and VIN (6–14 V) enable precise system-level thermal design without prototyping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current integrated DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS84A20 | 8 A max output, 2.5–6 V input, 0.6–3.6 V output; 7 mm × 7 mm QFN vs. 15 mm × 15 mm LGA | Lacks master/slave sync and pre-bias start-up; lower current rating limits use in 10 A FPGA cores | Preferred for compact, lower-current designs where board space is more constrained than thermal budget |
| Infineon IR3897 | 12 A max output, 4.5–18 V input, 0.6–3.3 V output; requires external inductor and compensation | Discrete power stage increases BOM count and layout sensitivity; no integrated soft-start capacitor | Chosen when design flexibility (e.g., custom inductors, higher Vin) outweighs integration benefits |
Compared with TPS84A20 and IR3897, SPDC12L00010 uniquely delivers 10 A in a self-contained LGA module with synchronization, pre-bias start-up, and programmable PG delay - making it optimal for thermally dense, high-reliability telecom and server applications where layout simplicity and robust sequencing are mandatory.

FAQ
What is the maximum allowable case temperature for continuous operation?
The SPDC12L00010 must not exceed 120 °C at the center of the top case (T1 point). Thermal de-rating tables in the datasheet specify reduced output current limits based on ambient temperature and input/output voltage combinations to maintain this limit on standard 4-layer FR4 PCBs.
Can SPDC12L00010 operate with an input voltage below 4.5 V?
Yes - the power stage (VIN) accepts 1.8 V minimum, but the controller (VCC) requires ≥4.5 V. Below 4.5 V on VIN, VCC must be supplied separately from a dedicated 4.5–14 V rail; tying VCC to VIN is only valid when VIN ≥4.5 V.
How is the Power Good delay calculated and what is its functional impact?
PG delay is set by a capacitor from PGDLY (L5) to SGND: PGdelay (μs) = 0.5 × CPGDLY (pF). This delay applies only to the rising edge of the PG signal, preventing false assertions during output voltage ramp-up while preserving immediate fault detection on falling edges.
Does SPDC12L00010 support output voltage tracking for multi-rail sequencing?
No - the device lacks dedicated tracking pins or analog control inputs for coordinated ramping with other supplies. Sequencing must be managed externally via inhibit (SS_INL) pin control or upstream power sequencers, as confirmed in Section 5.3 and Figure 5 of the datasheet.
