Product details
Overview
LM10000SDE/NOPB from Texas Instruments is an Adaptive Voltage Scaling (AVS) system controller IC that enables AVS functionality for non-AVS DC/DC regulators via PowerWise® Interface (PWI 2.0). It features a 7-bit current DAC (IAVS, 0–60 µA), programmable slew rate control, precision enable inputs (EN_BIAS, CONTROL), and CNTL_EN logic output for slave regulator sequencing - used in high-performance ASIC/FPGA power domains requiring dynamic voltage scaling between 0.6 V and 1.2 V.
For engineers reviewing the LM10000SDE/NOPB datasheet, LM10000SDE/NOPB pinout, LM10000SDE/NOPB application, or LM10000SDE/NOPB equivalent, this page delivers verified technical context on PWI 2.0 register mapping, IAVS feedback injection into slave regulator FB nodes, UVLO thresholds (2.27 V to 2.75 V), thermal resistance (54.7°C/W), and dual-state sequencing (Active/Sleep/Shutdown) with fault recovery via FLT_N.
Technical Context
The LM10000SDE/NOPB implements a Slave Power Controller (SPC 2.0) architecture compliant with PWI 2.0, supporting multi-master digital power management. Its core function is translating PWI Change Voltage Commands (CVC) into precise 7-bit current DAC outputs (IAVS and mirrored IAVS_MIRROR) injected into the feedback node of external regulators.
It operates with two independent logic enable paths: EN_BIAS initiates full initialization (<100 µs), while CONTROL toggles Active/Sleep states without reset delay. The device supports programmable ramp control (R10 register) with 8 discrete time-step options (1–16 µs) and 7 code-step options (1–16 LSB), enabling fine-grained dV/dt control over output voltage transitions.

Applications
| ASIC Core Voltage Scaling | FPGA Dynamic Power Management |
|---|---|
|
Use Scenario: High-performance ASICs dynamically adjust core voltage based on workload to minimize power consumption while maintaining timing closure. IC Role / Device Role / Timing Role: LM10000SDE/NOPB acts as AVS interface controller, translating APC2 commands into IAVS current injection at the FB node of a multi-phase buck controller (e.g., LM3754). Use Value: Enables sub-100 mV voltage steps with programmable slew rate, reducing dynamic power by up to 30% versus fixed-voltage operation under variable load conditions. |
Use Scenario: FPGA-based systems require rapid voltage transitions between performance states (e.g., compute vs. idle) without violating inrush limits. IC Role / Device Role / Timing Role: LM10000SDE/NOPB serves as slave power sequencer, using CONTROL pin for immediate Sleep/Active state switching and CNTL_EN to gate the enable input of a PMIC like LMZ10505. Use Value: Achieves <200 ns enable/disable response and supports 1–16 µs programmable ramp times, preventing rail collapse during state transitions. |
| Multi-Rail AVS System Coordination | Legacy Regulator AVS Retrofit |
|
Use Scenario: Systems with multiple AVS domains (e.g., CPU, GPU, memory) require synchronized voltage scaling across independent power rails. IC Role / Device Role / Timing Role: LM10000SDE/NOPB operates as one node in a multi-master PWI 2.0 bus, allowing centralized APC2 host to issue coordinated CVC commands to multiple LM10000 devices. Use Value: Supports simultaneous voltage updates across rails with deterministic timing, eliminating inter-rail skew and ensuring safe SoC-level power state transitions. |

IC Role / Device Role / Timing Role: LM10000SDE/NOPB functions as external AVS add-on, injecting IAVS current into the FB node of legacy regulators to override their fixed resistor-divider setpoint. Use Value: Adds full AVS functionality-including PWI register access, fault recovery, and slew control-to pre-existing power stages with zero changes to regulator selection or PCB layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar AVS interface controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS53689 | Integrated 3-phase PWM controller with built-in AVS support; no external DAC or PWI interface required | Replaces both LM10000SDE/NOPB and external controller; requires redesign of power stage and layout | Select when consolidating AVS and regulation into single IC; avoid when retrofitting existing non-AVS regulators |
| LM10011 | Pin-compatible successor with enhanced PWI 2.0 features, wider VPWI range (1.2–3.6 V), and improved DAC linearity (±1.5% FS) | Direct drop-in replacement with identical pinout and register map; supports newer APC2 firmware revisions | Select for new designs requiring higher DAC accuracy and broader I/O voltage compatibility; LM10000SDE/NOPB remains valid for legacy systems |
Compared with TPS53689, LM10000SDE/NOPB preserves design modularity by decoupling AVS control from regulation, enabling reuse of proven power stages. Compared with LM10011, it offers proven stability in long-lifecycle ASIC platforms but lacks updated DAC specs and extended VPWI range.

FAQ
What is the primary function of the LM10000SDE/NOPB in a power system?
The LM10000SDE/NOPB serves as an Adaptive Voltage Scaling (AVS) system controller that enables non-AVS DC/DC regulators to participate in PWI 2.0-based AVS systems. It does so by converting digital PWI commands into a precise 7-bit current DAC output (IAVS) injected into the feedback node of external regulators - thereby dynamically adjusting output voltage without modifying the regulator itself. This function is central to the LM10000SDE/NOPB's role in ASIC/FPGA power domains.
How does the LM10000SDE/NOPB interface with a slave regulator's feedback node?
The LM10000SDE/NOPB interfaces via its IAVS output pin, which sources 0–60 µA of current directly into the feedback (FB) node of an external regulator. This current alters the effective divider ratio per the equation VOUT = VFB × (1 + RFB1/RFB2) − IAVS × RFB1. Because the LM10000SDE/NOPB uses current injection rather than voltage injection, it avoids loading effects and maintains compatibility with any regulator having a standard resistive FB network - a key design feature confirmed in TI's SNVS643C datasheet.
Can the LM10000SDE/NOPB operate independently of the PWI interface?
Yes - the LM10000SDE/NOPB supports standalone operation using its logic inputs EN_BIAS and CONTROL. EN_BIAS initiates full initialization and powers internal circuitry, while CONTROL toggles between Active and Sleep states without requiring PWI communication. The CNTL_EN output reflects these states and can directly enable/disable the slave regulator. This dual-mode capability makes the LM10000SDE/NOPB suitable for both fully digital AVS systems and hybrid designs with partial hardware control.
What is the purpose of the FLT_N pin on the LM10000SDE/NOPB?
The FLT_N pin is an active-low fault input that resets and holds the IAVS current register (R0) to its default value (0x7F → 0 µA) whenever asserted. When connected to the PWGD (power-good) output of a slave regulator, FLT_N enables automatic recovery: if the slave regulator faults and pulls PWGD low, FLT_N forces LM10000SDE/NOPB to restore the default output voltage, allowing the regulator to restart cleanly. This behavior is explicitly documented in the "FAULT" state description and register R3 status bit mapping in the LM10000SDE/NOPB datasheet.
Does the LM10000SDE/NOPB support multiple devices on the same PWI bus?
Yes - the LM10000SDE/NOPB supports multi-master PWI 2.0 bus operation through its ADDR pin, which sets a unique 3-bit device address (0–7) via an external resistor-to-ground. Up to eight LM10000SDE/NOPB devices can coexist on a single PWI bus, each responding only to commands addressed to its configured ADDR value. This capability is essential for coordinating AVS across multiple power rails in complex SoCs and is validated in TI's typical application circuits and PWI register map documentation.
