Product details
Overview
TPS560200QDGKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive synchronous step-down DC/DC converter with integrated 0.95Ω high-side and 0.33Ω low-side MOSFETs, delivering 500mA continuous output current, 0.8V–6.5V adjustable output voltage, and 600kHz fixed-frequency operation using D-CAP2™ control. It enables compact, low-standby-power power supplies in EV charging stations and infotainment systems.
For engineers reviewing the TPS560200QDGKRQ1 datasheet, TPS560200QDGKRQ1 pinout, TPS560200QDGKRQ1 application, or TPS560200QDGKRQ1 equivalent, key selection considerations include its automotive-grade thermal performance (–40°C to 125°C TJ), advanced Eco-mode for light-load efficiency, internal 2ms soft-start, prebias-safe startup, and compatibility with ceramic and polymer output capacitors without external compensation.
Technical Context
The TPS560200QDGKRQ1 implements adaptive on-time D-CAP2™ control, combining constant on-time modulation with internal ripple injection to achieve fast transient response and stable operation with ultra-low-ESR ceramic capacitors. Its control loop requires no external compensation components and maintains pseudo-fixed 600kHz switching across input (4.5V–17V) and output (0.8V–6.5V) ranges.
Functional modes include continuous conduction mode (CCM) at medium-to-heavy loads, pulse-skipping Eco-mode below ~100mA, and standby shutdown via EN pin. Overcurrent protection uses valley-current sensing on the low-side FET, while thermal shutdown activates at 160°C with 10°C hysteresis - both non-latching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 17V - supports 12V automotive battery rails with ±10% tolerance and cold-crank margin. |
| Output Current | 500mA continuous - sufficient for powering microcontrollers, CAN transceivers, and display logic in automotive modules. |
| Output Voltage Accuracy | ±1.3% over temperature - ensures stable core or I/O rail regulation without post-regulation trimming. |
| Switching Frequency | 600kHz nominal - enables use of small 10µH inductors and reduces EMI filter size while maintaining efficiency. |
| Quiescent Current | 35–95µA in operating mode - minimizes standby power loss in always-on vehicle subsystems. |
| Thermal Shutdown Threshold | 160°C junction temperature - protects against sustained overload or poor PCB thermal design in enclosed enclosures. |
| ESD Rating (HBM) | ±2000V - meets AEC-Q100 H2 classification for robustness in manufacturing and field environments. |
Pinout & Package
TPS560200QDGKRQ1 is housed in an 8-pin VSSOP (DGK) package measuring 3mm × 4.9mm, optimized for thermal dissipation in automotive PCB layouts with exposed thermal pad connection to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-high logic control; floating defaults to enabled - allows simple system-level power sequencing without pull-up resistors. |
| GND (Pins 2, 8) | Power and signal ground | Dual GND pins reduce ground impedance and improve noise immunity for control circuitry and low-side switch return path. |
| VSENSE (Pin 3) | Feedback input | Monitors output voltage via resistor divider; internal 0.8V reference enables precise output programming from 0.8V to 6.5V. |
| NC (Pins 4, 5) | No connection | Internally unconnected - may be left floating or tied to GND for mechanical stability; no electrical function. |
| VIN (Pin 6) | Main power input | Supplies both control circuitry and high-side gate driver; requires local 10µF ceramic bypass capacitor for stability. |
| PH (Pin 7) | Switch node | Connects to inductor; carries high di/dt switching current - must be routed with minimal loop area to suppress EMI and voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control architecture | Enables <10µs load transient response with zero external compensation - simplifies design and improves reliability in dynamic automotive loads. |
| Advanced Eco-mode | Automatically transitions to pulse-skipping at light loads (<100mA), achieving >85% efficiency at 1mA - critical for always-on telematics modules. |
| Prebias-safe soft-start | Prevents reverse current flow during startup into precharged outputs - eliminates need for external reverse-blocking diodes in legacy designs. |
| Integrated power MOSFETs | 0.95Ω HS / 0.33Ω LS RDS(on) - delivers >90% peak efficiency at 500mA with minimal BOM count and footprint. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C junction operation with HBM ±2000V and CDM ±500V ESD - meets functional safety requirements for ASIL-B systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMQ66430QRNXTQ1 | Higher 3A output current, 2.5V–36V input, 2.1MHz switching - larger package (16-pin QFN), higher quiescent current (26µA vs 60µA typical). | Targeted at higher-power ADAS domain controllers; not cost-optimized for sub-1A rails. | Select when >1A output or wider VIN range is required; avoid if board space or light-load efficiency is critical. |
| TPS62865ARGTR | Pin-compatible 600kHz 3A buck with PMBus interface, 2.7V–6V input - lacks AEC-Q100 qualification and automotive temp range. | Designed for industrial/commercial applications only; unsuitable for under-hood or safety-critical use. | Consider only for non-automotive designs requiring digital monitoring; not a drop-in replacement for TPS560200QDGKRQ1. |
Compared with LMQ66430QRNXTQ1 and TPS62865ARGTR, the TPS560200QDGKRQ1 offers optimal balance of AEC-Q100 compliance, ultra-low quiescent current, and minimal BOM count for sub-1A automotive point-of-load applications - making it the preferred choice where cost, thermal footprint, and functional safety are jointly constrained.

FAQ
What is the maximum output current capability of the TPS560200QDGKRQ1?
The TPS560200QDGKRQ1 delivers 500mA continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 4.5V–17V). Its integrated 0.95Ω high-side and 0.33Ω low-side MOSFETs enable this rating with typical efficiency >90% at full load. Peak current capability exceeds 670mA per valley-current limiting specification, but sustained operation above 500mA requires careful thermal management.
Does the TPS560200QDGKRQ1 require external compensation components?
No, the TPS560200QDGKRQ1 does not require external compensation components. Its D-CAP2™ control architecture incorporates internal ripple injection and adaptive on-time modulation, enabling stable operation with ceramic, POSCAP, or SP-CAP output capacitors without adding external RC networks or type-II/III compensators - significantly reducing design complexity and BOM count.
Can the TPS560200QDGKRQ1 safely start up into a prebiased output voltage?
Yes, the TPS560200QDGKRQ1 features proprietary prebias-safe soft-start. When enabled, it gradually ramps the reference voltage while controlling low-side FET gate pulses cycle-by-cycle to prevent reverse current flow into a precharged output. This eliminates the need for external reverse-blocking diodes and avoids output voltage overshoot or system reset during hot-swap scenarios.
What is the switching frequency of the TPS560200QDGKRQ1 and how is it controlled?
The TPS560200QDGKRQ1 operates at a nominal 600kHz switching frequency using adaptive on-time control. The on-time is dynamically adjusted based on VIN and VOUT to maintain pseudo-constant frequency across input and output variations. No external clock or synchronization pin is required, and frequency remains stable within ±5% over load and line conditions per typical characterization data.
Is the TPS560200QDGKRQ1 qualified for automotive applications?
Yes, the TPS560200QDGKRQ1 is AEC-Q100 Grade 1 qualified, certified for operation from –40°C to +125°C junction temperature. It meets HBM ±2000V and CDM ±500V ESD requirements, and is manufactured in TI's ISO/TS 16949-certified facilities - making it suitable for safety-critical automotive applications including infotainment, body control, and ADAS subsystems.
