Product details
Overview
TPS62993QRYTRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous buck converter delivering up to 3 A continuous output current with ±1.5% VOUT accuracy across –40°C to +165°C junction temperature, 4 µA typical quiescent current, and DCS-Control topology for fast transient response in ADAS power rails.
For engineers reviewing the TPS62993QRYTRQ1 datasheet, TPS62993QRYTRQ1 pinout, TPS62993QRYTRQ1 application, or TPS62993QRYTRQ1 equivalent, this device supports configurable 1-MHz/2.5-MHz switching, internal/external VOUT selection (0.4 V–5.5 V), forced PWM or auto PFM mode, and power-good signaling - all in a wettable 2.2 mm × 2.0 mm VQFN package.
Technical Context
The TPS62993QRYTRQ1 implements TI's DCS-Control topology, combining voltage-mode stability with hysteretic-like transient response via direct control of the high-side FET's on-time using a fast comparator and internal 1-V reference. It uses seamless PWM/PFM transition and internal compensation to eliminate external loop components.
Its MODE/S-CONF pin enables dual-function configuration: resistor-based selection of switching frequency (1 MHz or 2.5 MHz), VOUT source (FB or VSET), output discharge, and operating mode (auto PFM with AEE or forced PWM); dynamic mode change is supported only when the pin is driven logic-high or logic-low at startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 10 V - supports 5 V, 9 V, and multi-cell Li-ion rails without pre-regulation. |
| Output Current | Up to 3 A continuous - sufficient for SoC core rails, camera modules, and radar MMIC biasing. |
| Quiescent Current | 4 µA typical in power-save mode - enables >1-year battery standby in always-on vehicle systems. |
| Output Voltage Accuracy | ±1.5% over –40°C to +165°C TJ - ensures reliable regulation under extreme under-hood thermal stress. |
| Switching Frequency | Selectable 1.0 MHz or 2.5 MHz - balances EMI control (1 MHz) vs. size efficiency (2.5 MHz with 1 µH inductor). |
| RDS(ON) | 62 mΩ (HS) / 22 mΩ (LS) - minimizes conduction loss at full load, supporting >92% peak efficiency at 6 VIN/3.3 VOUT. |
| Package | VQFN-9 (RYT), 2.2 mm × 2.0 mm, 0.5 mm pitch - optimized for single-layer PCB routing and automated optical inspection. |
Pinout & Package
VQFN-9 (RYT) package: 2.2 mm × 2.0 mm body, 0.5 mm pitch, wettable flanks for solder joint inspection. Exposed thermal pad (Pin 4) connected to GND for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PG (Pin 1) | Open-drain power-good output | Signals VOUT regulation status; requires external pullup; enables sequencing with downstream ICs. |
| SW (Pin 2) | Switch node | Connects internal HS/LS FETs to external inductor; critical for EMI layout and thermal path management. |
| VOS (Pin 3) | Output voltage sense | Direct Kelvin connection to output capacitor positive terminal - eliminates trace IR drop error in VSET mode. |
| GND (Pin 4) | Power ground | Primary thermal and current return path; must be low-impedance plane tie to exposed pad. |
| EN (Pin 5) | Enable input | Logic-compatible (0.85 VIL/1.0 VIH); precise threshold enables clean system-level power sequencing. |
| VIN (Pin 6) | Input supply | Accepts 3–10 V; requires local 3–10 µF ceramic input capacitor placed adjacent to VIN/GND pins. |
| MODE/S-CONF (Pin 7) | Configuration & mode select | Resistor-programmable for 16 VOUT options, 2 fSW, discharge enable, and PFM/PWM behavior - no firmware needed. |
| SS/TR (Pin 8) | Soft-start & tracking input | 2.5 µA current source sets ramp rate; also accepts external voltage for supply tracking during power-up/down. |
| FB/VSET (Pin 9) | Feedback or VOUT setpoint input | Configurable as FB (0.6 V reference) for adjustable outputs or VSET (resistor-to-voltage mapping) for fixed outputs. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables <10 µs load transient recovery with minimal output capacitance - critical for processor DVFS events. |
| 100% duty cycle operation | Permits VOUT ≥ VIN – dropout (e.g., 5 V out from 5.2 V rail) - extends usable input range in battery-sag conditions. |
| No external bootstrap capacitor | Reduces BOM count and layout area; simplifies design for space-constrained automotive modules. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient (TA) and +165°C junction - meets under-hood thermal requirements. |

FAQ
What is the maximum junction temperature rating for the TPS62993QRYTRQ1?
The TPS62993QRYTRQ1 is rated for operation up to +165°C junction temperature, validated per AEC-Q100 with extended thermal characterization. This enables deployment in under-hood locations such as radar front-end modules and engine bay ECUs without thermal derating, unlike standard Grade 1 parts limited to +125°C TJ.
How does the MODE/S-CONF pin configure the TPS62993QRYTRQ1?
The MODE/S-CONF pin configures the TPS62993QRYTRQ1 via resistor value or logic level: resistor selection (7.15 kΩ–118 kΩ) sets switching frequency (1/2.5 MHz), VOUT source (FB/VSET), output discharge, and PFM/PWM mode; logic-high/low enables dynamic mode switching during operation without power cycling.
Does the TPS62993QRYTRQ1 require an external bootstrap capacitor?
No, the TPS62993QRYTRQ1 integrates bootstrap circuitry and does not require an external bootstrap capacitor. This reduces bill-of-materials count, PCB area, and layout complexity - particularly beneficial in space-constrained automotive modules like camera ECU housings.
What output voltage options does the TPS62993QRYTRQ1 support?
The TPS62993QRYTRQ1 supports two configuration methods: (1) external feedback via FB pin (0.6 V reference, 0.6–5.5 V VOUT), or (2) internal VSET divider with 16 factory-programmed options (0.4 V–5.5 V), selected by resistor to GND on FB/VSET pin per Table 8-2 in the datasheet.
Is the TPS62993QRYTRQ1 pin-compatible with other devices in the TPS6299x-Q1 family?
Yes, the TPS62993QRYTRQ1 shares the same RYT VQFN-9 package, pinout, and footprint with TPS62992QRYTRQ1, TPS62903QRYTRQ1, and TPS62902QRYTRQ1 - enabling scalable power design and BOM rationalization across 1-A to 3-A automotive buck applications.
