Product details
Overview
TPS6286920CRQYR from Texas Instruments is a 4-A/6-A synchronous step-down DC-DC converter with I²C interface, designed for high-efficiency core power delivery in space-constrained applications. It operates from 2.4 V to 5.5 V input, delivers 1.2 V output with ±1% accuracy, features DCS-Control™ architecture for fast transient response, and integrates 11-mΩ/10.5-mΩ internal MOSFETs - used in LPDDR5 VDDQ rail supply and FPGA core voltage regulation.
For engineers reviewing the TPS6286920CRQYR datasheet, TPS6286920CRQYR pinout, TPS6286920CRQYR application, or TPS6286920CRQYR equivalent, key selection criteria include its fixed 1.2-V start-up output, PG (power-good) pin function, QFN-9 1.5×2.5-mm package, 2.4-MHz switching frequency, and I²C-configurable protection modes including hiccup vs. latching short-circuit response.
Technical Context
The TPS6286920CRQYR implements DCS-Control™ topology, enabling seamless PWM-to-Power-Save Mode transition without output disturbance. Its 2.4-MHz fixed-frequency PWM operation ensures low output ripple, while the 100% duty-cycle mode supports near-input-output voltage operation under light load.
This variant uses the VSET/VID pin as PG (open-drain power-good indicator), not for voltage selection - confirmed by Device Options table. It supports I²C up to 3.4 Mbps, enables dynamic configuration of forced-PWM mode, output discharge, ramp speed, and thermal pre-warning, all while maintaining ±1% output accuracy across –40°C to 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4 V to 5.5 V - supports single-cell Li-ion, USB PD, and industrial 3.3-V/5-V rails without external LDO pre-regulation. |
| Output Current Rating | 6 A - rated for TPS62869 family; enables direct powering of high-current FPGA cores or ASIC logic blocks. |
| Start-up Output Voltage | 1.2 V - fixed at power-on via external resistor on VSET/VID pin; eliminates need for I²C initialization before regulation. |
| Output Voltage Accuracy | ±1% - tight tolerance over full temperature and load range ensures reliable LPDDR5 VDDQ compliance and timing margin. |
| Switching Frequency | 2.4 MHz - enables use of ultra-small 0.22-µH inductors and reduces EMI filter footprint in compact PCB layouts. |
| I²C Interface Speed | Up to 3.4 Mbps - supports high-speed dynamic voltage scaling (DVS) during runtime without interrupting system operation. |
| Thermal Protection | 130°C thermal warning + 150°C shutdown - provides early fault indication and safe fail-safe behavior in thermally dense SoC modules. |
Pinout & Package
TPS6286920CRQYR is housed in a 1.5-mm × 2.5-mm × 1.0-mm, 9-pin QFN package (RQY) with 0.5-mm pitch and wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AGND | Analog ground reference | Separate low-noise return path for feedback and control circuitry; must be connected to quiet analog ground plane. |
| 2 PGND | Power ground return | High-current return for switch node and inductor; requires low-inductance connection to thermal pad and power ground. |
| 3 VIN | Main input power supply | Accepts 2.4–5.5 V; requires local 10-µF ceramic input capacitor placed adjacent to pin for stability and EMI suppression. |
| 4 EN | Enable control input | Active-high logic; internal 100-kΩ pull-down ensures default disable; rising-edge triggers 100–900 µs enable delay before switching begins. |
| 5 SDA | I²C serial data line | Open-drain, 3.4-Mbps capable; requires external pull-up to 1.8–5.5 V; must not float - tie to AGND if unused. |
| 6 SCL | I²C serial clock line | Open-drain, 3.4-Mbps capable; same pull-up and termination rules as SDA; critical for DVS and protection reconfiguration. |
| 7 SW | Switch node output | Connects to inductor; carries high di/dt current; requires short, wide trace and minimized loop area to reduce EMI and ringing. |
| 8 VOS | Output voltage sense | Direct Kelvin connection to output capacitor anode; enables accurate remote sensing and compensates for PCB IR drop. |
| 9 PG | Power-good open-drain output | Asserts high when VOUT reaches 91–120% of nominal (1.2 V); used for system sequencing and fault monitoring; pull-up required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6286910CRQY | Start-up output = 0.9 V; same 6-A rating, QFN-9 package, and I²C interface - but uses VSET/VID for DVS register selection, not PG. | Used where dynamic voltage scaling across 0.4–1.675 V range is required (e.g., multi-core SoCs), not fixed 1.2-V rails. | Select TPS6286910CRQY only if variable output voltage via I²C is needed; TPS6286920CRQY is preferred for fixed 1.2-V LPDDR5 VDDQ or FPGA core rails. |
| TPS6286820CRQY | 4-A rating (vs. 6-A); identical 1.2-V start-up, PG pin function, QFN-9 package, and I²C feature set - lower current capability reflects internal FET RDS(on) derating. | Suitable for lower-power FPGAs (e.g., Lattice CrossLink-NX) or microcontrollers where peak load <4 A. | Choose TPS6286820CRQY for cost-sensitive, lower-current designs; TPS6286920CRQY provides headroom for future performance scaling and transient surges. |
Compared with TPS6286910CRQY and TPS6286820CRQY, the TPS6286920CRQY uniquely combines 6-A capability, fixed 1.2-V start-up, and dedicated PG functionality - making it the optimal choice for LPDDR5 VDDQ and high-performance FPGA core supplies where voltage stability and sequencing integrity are non-negotiable.

FAQ
What is the start-up output voltage of the TPS6286920CRQYR?
The TPS6286920CRQYR has a fixed start-up output voltage of 1.2 V, selected by an external resistor on the VSET/VID pin. This value is factory-configured per Device Options table and cannot be altered post-manufacture. The TPS6286920CRQYR does not support dynamic voltage scaling at power-on - its I²C interface enables configuration only after the initial 1-ms soft-start ramp completes.
Does the TPS6286920CRQYR support forced PWM mode?
Yes, the TPS6286920CRQYR supports forced PWM (FPWM) mode via I²C register write to the CONTROL register. In FPWM mode, the device maintains 2.4-MHz switching regardless of load, reducing output voltage ripple and simplifying EMI filtering - essential for noise-sensitive analog or RF subsystems powered from the same rail.
What is the function of Pin 9 (VSET/VID or PG) on the TPS6286920CRQYR?
On the TPS6286920CRQYR, Pin 9 functions exclusively as PG (power-good open-drain output), not as VSET/VID. It asserts high when output voltage reaches 91–120% of 1.2 V and remains active during normal operation - providing system-level power sequencing and fault detection without requiring external comparators or supervisors.
What thermal protection features does the TPS6286920CRQYR include?
The TPS6286920CRQYR includes thermal pre-warning at 130°C (signaled via I²C status register) and thermal shutdown at 150°C. Both thresholds have 20°C hysteresis. These features allow host firmware to initiate thermal throttling or log events before catastrophic failure - critical for fanless embedded systems and sealed industrial enclosures where airflow is limited.
Can the TPS6286920CRQYR operate with a pre-biased output capacitor?
Yes, the TPS6286920CRQYR supports start-up into a pre-biased output. When enabled, it detects the existing output voltage and ramps from that level to 1.2 V using its internal soft-start circuitry - preventing reverse current flow and ensuring safe hot-plug operation in modular systems and field-upgradeable storage controllers.
