Product details
Overview
LM10692BRMYT from Texas Instruments is a fully integrated power management unit (PMU) designed specifically for SandForce SF3700 SSD controllers. It integrates six SPI/I²C-programmable buck regulators, delivers up to 95% efficiency, operates at 2 MHz switching frequency, and supports programmable output voltages from 0.8 V to 3.3 V across six rails-including 2.5A 1.8V CPE and 2.5A 1.1V CPE-enabling optimized power delivery for M.2 solid-state drives.
For engineers reviewing the LM10692BRMYT datasheet, LM10692BRMYT pinout, LM10692BRMYT application, or LM10692BRMYT equivalent, key selection considerations include I²C-based voltage programmability, phase-shifted buck operation for reduced input ripple, independent AON/CPE rail control with Power Good outputs, bypass mode on Buck1 for 3.3V M.2 applications, and thermal/over-current protection tailored for NAND flash power systems.
Technical Context
The LM10692BRMYT implements six synchronous buck regulators with independent enable and Power Good signals for Always-On (AON) and Core Power (CPE) domains. Each regulator supports programmable output voltage via I²C interface, with ±1% feedback accuracy and automatic soft-start to limit inrush current.
It features phase-shifted switching across multiple bucks to reduce input capacitor stress, PFM mode for light-load efficiency, fast active discharge, and built-in thermal shutdown. The device uses a single 2.5V–5.5V input supply and supports customizable startup sequencing for SSD controller coordination.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65988ARSLR | USB-C PD + PMU combo; lacks dedicated NAND rail sequencing and bypass mode | Targeted at USB host systems, not SF3700 SSDs; no native support for AON/CPE domain separation | Use only if redesigning for USB-C PD integration; requires external sequencing logic for NAND rails |
| RTQ2136B-QA | Quad-buck with I²C, but no bypass mode, lower max current (1.5A), and no PFAIL input | Designed for automotive infotainment; lacks SF3700-specific register map and startup timing | Acceptable for generic SSD-like loads only if Buck1 bypass and PFAIL are omitted from design |
Compared with TPS65988ARSLR and RTQ2136B-QA, the LM10692BRMYT uniquely integrates SF3700-optimized AON/CPE rail partitioning, Buck1 bypass for M.2, and PFAIL-triggered safe shutdown-making it the only drop-in PMU for SandForce-based SSDs without layout or firmware rework.

FAQ
What is the primary function of the LM10692BRMYT in an SSD system?
The LM10692BRMYT serves as a fully integrated power management unit for SandForce SF3700 SSD controllers. It provides six programmable buck regulators to power AON and CPE domains, implements I²C-based dynamic voltage scaling, supports bypass mode for 3.3V M.2 compliance, and delivers coordinated startup/shutdown sequencing. Its design eliminates up to six discrete power components in the LM10692BRMYT-based SSD architecture.
Does the LM10692BRMYT support both I²C and SPI interfaces?
The LM10692BRMYT supports I²C communication for configuration, monitoring, and control-including dynamic voltage scaling, sleep mode entry, and fault reporting. While some documentation references SPI programmability, the LM10692BRMYT datasheet and reference designs exclusively specify I²C (SCL/SDA pins) as the supported serial interface; no SPI pins or timing specifications are defined for the LM10692BRMYT.
What is the purpose of the VIN_MODE pin on the LM10692BRMYT?
The VIN_MODE pin on the LM10692BRMYT selects bypass mode for Buck1, enabling direct pass-through of the AVIN supply to the output without inductor involvement. This feature satisfies M.2 specification requirements for 3.3V rail delivery, reduces board area, eliminates inductor losses, and improves reliability in compact SSD modules using the LM10692BRMYT.
How does the LM10692BRMYT handle thermal protection?
The LM10692BRMYT includes integrated thermal shutdown that disables all regulators when die temperature exceeds 150°C. Recovery occurs automatically after temperature falls below 135°C hysteresis. This protection is implemented entirely within the LM10692BRMYT silicon and requires no external components, ensuring robust operation in thermally dense M.2 SSD environments.
Can the LM10692BRMYT be used with controllers other than SandForce SF3700?
The LM10692BRMYT is specifically architected for SandForce SF3700 controllers, with register maps, startup timing, AON/CPE rail assignments, and I²C command sets aligned to that platform. While basic buck functionality may operate with other controllers, features like PFAIL-driven shutdown, sequenced enable timing, and SF3700-specific DVS profiles are not guaranteed outside that ecosystem - the LM10692BRMYT is not validated for non-SF3700 use.
