Product details
Overview
TPS62872Y1QWRXSRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering up to 12A continuous output current, supporting 2.7V–6V input, ±1% output voltage accuracy, differential remote sensing, and I²C interface (address 0x42) for dynamic voltage scaling in high-performance core supplies.
For engineers reviewing the TPS62872Y1QWRXSRQ1 datasheet, TPS62872Y1QWRXSRQ1 pinout, TPS62872Y1QWRXSRQ1 application, or TPS62872Y1QWRXSRQ1 equivalent, key selection criteria include stackable 12A operation, resistor-selectable switching frequency (1.5/2.25/2.5/3.0 MHz), thermal warning threshold at 150°C, wettable-flank VQFN-16 package, and functional safety documentation support.
Technical Context
The TPS62872Y1QWRXSRQ1 implements a fixed-frequency DCS-Control topology optimized for fast load transients and low output voltage ripple. It integrates 7 mΩ high-side and 4.5 mΩ low-side MOSFETs, supports power-save or forced-PWM mode via MODE/SYNC pin, and enables precise point-of-load regulation using differential remote sense (VOSNS/GOSNS).
Its I²C interface (up to 1 MHz) provides real-time monitoring of output voltage, junction temperature, and thermal warnings, while stackable architecture allows parallel operation with synchronized switching and shared COMP compensation network across identical-current devices.

Pinout & Package
RXS package: 16-pin VQFN (2.55 mm × 3.55 mm × 1 mm) with exposed thermal pad soldered to GND for optimal thermal performance (RθJB = 7.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COMP | Control loop compensation node | Connects external RC network to GOSNS; in stacked configurations, all COMP pins must be tied together |
| 2 - GOSNS | Differential ground sense input | Completes remote-sense pair with VOSNS; enables <±1% regulation at point-of-load despite PCB IR drop |
| 3 - VOSNS | Differential output voltage sense input | Measures true load voltage; rejects noise and trace resistance errors when paired with GOSNS |
| 4 - EN | Enable control input | Active-high logic; requires ≥15 kΩ series resistor; interconnects across stacked devices for coordinated startup |
| 5,9 - VIN | Main power input | Dual input pins reduce parasitic inductance; each requires local 5–10 µF ceramic capacitor to GND |
| 6,8 - GND | Power and signal ground | Low-inductance return path; connects directly to exposed thermal pad for thermal and electrical integrity |
| 7 - SW | Power switch node | Drives external inductor; high di/dt node requiring tight layout and minimized loop area |
| 10 - PG | Open-drain power-good indicator | Signals valid regulation (92–98% undervoltage, 102–108% overvoltage window); daisy-chained in stacks |
| 11 - MODE/SYNC | Operating mode select / clock sync input | Pull low for power-save mode; pull high for forced-PWM; accepts external sync clock in 1.3–3.3 MHz range |
| 12 - SDA | I²C data line | Bi-directional open-drain interface; requires external pullup; grounded for secondary devices in stack |
| 13 - SCL | I²C clock line | Input-only clock; requires external pullup; grounded for secondary devices in stack |
| 14 - SYNC_OUT | Internal clock output | Drives MODE/SYNC of next device in daisy-chain; pulled to GND via 47 kΩ to configure as secondary |
| 15 - VSEL | Startup voltage select | Resistor-to-GND/VIN sets default VOUT at power-on (0.875 V for Y1 variant); internal 5.5–9 kΩ pullup |
| 16 - FSEL | Frequency select | Resistor-to-GND/VIN selects 1.5/2.25/2.5/3.0 MHz; internal 1.3–2.2 kΩ pulldown |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62873Y1QWRXSRQ1 | 15A rated; higher RDS(on) (7/4.5 mΩ → 6.5/4.2 mΩ); same I²C address space (0x43) | Required where peak current exceeds 12A; higher thermal margin but larger solution size | Select when system load demands >12A continuous; verify PCB copper and thermal pad design for increased power dissipation |

FAQ
What is the default startup output voltage of the TPS62872Y1QWRXSRQ1?
The TPS62872Y1QWRXSRQ1 has a factory-configured default startup output voltage of 0.875 V, selected via internal VSEL pin configuration (shorted to VIN). This value is confirmed in Table 4-1 of the datasheet and remains stable across temperature and input voltage variations within spec.
Does the TPS62872Y1QWRXSRQ1 support stacking with other current ratings?
No - the TPS62872Y1QWRXSRQ1 must only be stacked with identical 12A variants (e.g., other TPS62872Y1QWRXSRQ1 units). Mixing with 6A, 9A, or 15A devices risks unbalanced current sharing and premature current-limit activation in the lower-rated unit, as explicitly stated in Section 7.1.
What is the maximum supported I²C clock frequency for the TPS62872Y1QWRXSRQ1?
The TPS62872Y1QWRXSRQ1 supports I²C Fast Mode Plus operation up to 1 MHz, as specified in Section 6.6. This enables rapid register reads (e.g., temperature, VOUT) and writes (e.g., voltage update, spread-spectrum enable) without compromising timing margins in automotive microcontroller environments.
How does the differential remote sensing work on the TPS62872Y1QWRXSRQ1?
The TPS62872Y1QWRXSRQ1 uses dedicated VOSNS and GOSNS pins to measure output voltage directly at the load, rejecting voltage drop across PCB traces. The internal error amplifier compares this sensed value against the reference, achieving ±1% DC accuracy regardless of board layout or current level - a capability verified in Section 6.5.
Is the TPS62872Y1QWRXSRQ1 pin-compatible with non-I²C variants like TPS62872N1QWRXSRQ1?
Yes - the TPS62872Y1QWRXSRQ1 shares identical RXS VQFN-16 pinout and footprint with all TPS62872x-Q1 variants, including non-I²C versions. However, SDA and SCL pins must be tied to GND on non-I²C parts, and VSEL/FSEL resistor values may differ per variant's factory settings.
