Product details
Overview
TPS560200QDGKTQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified synchronous step-down DC/DC converter for automotive applications, integrating 0.95Ω high-side and 0.33Ω low-side MOSFETs, delivering 500mA continuous output current with 0.8V–6.5V adjustable output voltage, ±1.3% reference accuracy, and D-CAP2™ control enabling fast transient response without external compensation.
For engineers reviewing the TPS560200QDGKTQ1 datasheet, TPS560200QDGKTQ1 pinout, TPS560200QDGKTQ1 application, or TPS560200QDGKTQ1 equivalent, key selection considerations include its 600kHz fixed-frequency operation, 2ms internal soft-start, prebias-safe startup, thermal shutdown (160°C), and compatibility with ceramic and low-ESR polymer output capacitors in space-constrained automotive power rails.
Technical Context
The TPS560200QDGKTQ1 implements adaptive on-time D-CAP2™ control, combining constant on-time PWM with internal ripple-simulation to achieve stable regulation across ceramic and POSCAP/SP-CAP output capacitors without external compensation. Its valley-current-based overcurrent protection monitors low-side FET voltage during conduction to detect fault conditions.
It operates in three functional modes: continuous conduction mode (CCM) at full load (quasi-fixed 600kHz), pulse-skipping Eco-mode at light loads for high efficiency, and standby mode when EN is pulled low - all supported by integrated UVLO (4.35V rise / 4.15V fall), 2ms soft-start, and non-latching thermal shutdown with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 17V - supports wide automotive battery rail including cold-crank (≥4.5V) and load-dump transients (≤17V) |
| Output Current | 500mA continuous - sufficient for powering microcontrollers, sensors, and infotainment subsystems |
| Output Voltage Range | 0.8V to 6.5V - programmable via external resistor divider for core logic, I/O, or analog supply rails |
| Reference Accuracy | ±1.3% over –40°C to 125°C - ensures tight output regulation across automotive temperature range |
| Switching Frequency | 600kHz nominal - enables compact magnetics and EMI filtering while balancing efficiency and thermal performance |
| High-Side RDS(on) | 0.95Ω typical - reduces conduction loss at 500mA, supporting >90% peak efficiency at mid-load |
| Low-Side RDS(on) | 0.33Ω typical - minimizes synchronous rectification losses and improves light-load efficiency |
| Soft-Start Time | 2ms fixed internal - prevents inrush current and ensures controlled ramp-up into regulation |
Pinout & Package
TPS560200QDGKTQ1 is housed in an 8-pin VSSOP (DGK) package measuring 3mm × 4.9mm, optimized for thermal performance and PCB area efficiency in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-high logic control; floating enables operation; threshold 1.16–1.29V rising edge |
| GND (Pins 2, 8) | Power and signal ground | Common return for control circuitry and low-side MOSFET; must be connected to low-impedance PCB ground plane |
| VSENSE (Pin 3) | Feedback input | Monitors output voltage via resistor divider; internal 0.8V reference sets regulation point |
| NC (Pins 4, 5) | No connection | Internally unconnected; may be left floating or tied to GND/VOUT per layout requirements |
| VIN (Pin 6) | Main power input | Supplies control circuitry and high-side gate driver; requires local 10µF ceramic bypass capacitor |
| PH (Pin 7) | Switch node | Connects to inductor; carries high di/dt switching current - requires minimal loop area and direct copper routing |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562201QDGKRQ1 | 2A output current, same 4.5–17V input, identical DGK package and pinout | Higher current capability suits dual-core MCUs or multi-sensor nodes | Select when >500mA load margin or future-proofing is required; shares layout and firmware compatibility |

FAQ
What is the maximum recommended input voltage for TPS560200QDGKTQ1?
The absolute maximum input voltage for TPS560200QDGKTQ1 is 19V, but the recommended operating range is strictly 4.5V to 17V per TI's datasheet Section 5.3. Exceeding 17V risks violating safe operating area limits during transients, even if within absolute max ratings. The device includes internal UVLO that disables operation below 4.35V (rising) and re-enables only after VIN exceeds 4.5V, ensuring robust cold-crank behavior. TPS560200QDGKTQ1 must not be operated continuously above 17V in production designs.
Does TPS560200QDGKTQ1 support ceramic output capacitors?
Yes, TPS560200QDGKTQ1 is explicitly designed to operate stably with ultra-low-ESR ceramic capacitors, as confirmed in Section 6.1 and Figure 7-2 of the datasheet. Its D-CAP2™ control architecture eliminates reliance on ESR-induced ripple for loop stability, unlike traditional voltage-mode controllers. TI recommends X5R/X7R 10µF ceramics (e.g., Murata GRM32DR61E106KA12L) placed close to the VOUT and GND pins. TPS560200QDGKTQ1 also supports POSCAP and SP-CAP types, offering flexibility for noise-sensitive or space-constrained applications.
What is the purpose of the NC pins on TPS560200QDGKTQ1?
Pins 4 and 5 of TPS560200QDGKTQ1 are designated No Connect (NC) and are internally unconnected die bond pads. They may be left floating, tied to GND, or connected to VOUT depending on PCB layout needs - such as improving thermal conduction, reducing crosstalk, or matching copper pour symmetry. TI's layout guidelines (Section 7.4.2) show these pins adjacent to PH and GND; no electrical function is assigned, and connecting them does not affect regulation, efficiency, or protection features of TPS560200QDGKTQ1.
How does TPS560200QDGKTQ1 handle startup into a prebiased output?
TPS560200QDGKTQ1 implements proprietary prebias-safe startup: when EN goes high and VSENSE > internal soft-start voltage, the controller gradually enables low-side FET gate pulses with narrow on-time, incrementing cycle-by-cycle until reaching full duty. This prevents sinking current from the precharged rail, avoiding output voltage collapse or system reset. Confirmed in Section 6.3.4 and Figure 7-9, this feature makes TPS560200QDGKTQ1 suitable for hot-plug and multi-rail sequencing applications where output caps may retain charge before enable assertion.
Is TPS560200QDGKTQ1 pin-compatible with any other TI buck converters?
TPS560200QDGKTQ1 shares the same 8-pin DGK (VSSOP) package and pinout with TPS562201QDGKRQ1, including identical EN, VSENSE, VIN, PH, and GND assignments. This enables drop-in replacement for higher-current applications up to 2A without PCB modification. However, it is not pin-compatible with TPS54202QDDCRQ1 (SOT-23-6) or LM61480QRNXTQ1 (12-pin WSON). Always verify feedback resistor values and inductor saturation current when substituting, as TPS560200QDGKTQ1's 500mA rating imposes distinct thermal and ripple constraints.
