Product details
Overview
TPS560430YQDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified synchronous buck converter delivering up to 600 mA output current with 4 V to 36 V input range, fixed 2.1 MHz switching frequency, and ±0.5% reference voltage accuracy at room temperature - used in automotive camera power supplies and USB chargers.
For engineers reviewing the TPS560430YQDBVRQ1 datasheet, TPS560430YQDBVRQ1 pinout, TPS560430YQDBVRQ1 application, or TPS560430YQDBVRQ1 equivalent, key selection considerations include PFM-mode light-load efficiency, minimum 60 ns on-time for high VIN-to-VOUT ratios, hiccup-mode short-circuit protection, and SOT-23-6 package compatibility with layout-constrained automotive modules.
Technical Context
The TPS560430YQDBVRQ1 implements fixed-frequency peak-current mode control with internal compensation, enabling stable regulation across wide input and load ranges without external loop components. It supports startup with pre-biased output and features precision enable with 123 mV hysteresis for reliable system sequencing.
Its PFM operation mode reduces quiescent current to 80–120 µA at light loads while maintaining 98% maximum duty cycle and 60 ns minimum on-time - critical for high step-down ratios (e.g., 24 V → 3.3 V) in automotive head units and on-board chargers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 36 V - supports direct connection to automotive battery rails including cold-crank (4.5 V) and load-dump (36 V) transients. |
| Output Current | 600 mA continuous - sufficient for powering image sensors, USB PD sink controllers, and infotainment SoCs. |
| Switching Frequency | 2.1 MHz (±10%) - enables use of compact 1–2.2 µH inductors and reduces EMI filtering requirements. |
| Reference Voltage | 1.000 V ±0.5% at 25°C - ensures ≤1% output voltage error over temperature when using 1% FB resistors. |
| Min On-Time | 60 ns - allows regulation down to 3.3 V from 36 V input without frequency foldback below ~133 kHz. |
| Quiescent Current | 80–120 µA in PFM mode - extends battery runtime in always-on camera modules during standby. |
| Thermal Shutdown | 170°C with 12°C hysteresis - protects against sustained overload in sealed enclosures like rear-view camera housings. |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm), thermally enhanced with exposed pad (not electrically connected), suitable for reflow assembly and space-constrained PCBs in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CB | Bootstrap capacitor connection | Connects 100 nF ceramic capacitor to SW; supplies gate drive voltage for integrated high-side MOSFET. |
| GND | Power ground | Common return path for input/output capacitors and low-side FET source; requires shortest possible trace to CIN/COUT. |
| FB | Voltage feedback input | Monitors resistor divider output; sets VOUT = 1.0 V × (1 + RFBT/RFBB); must not be shorted to GND during operation. |
| EN | Precision enable input | Active-high control with 1.23 V threshold and 123 mV hysteresis; supports system UVLO via external resistor divider. |
| VIN | Main power input | Supplies internal LDO and high-side FET; requires local 10 µF ceramic bypass capacitor directly between VIN and GND. |
| SW | Switch node | Drives external inductor; connects internally to source of high-side FET and drain of low-side FET; high dv/dt node requiring tight layout. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated synchronous rectification | Eliminates external Schottky diode - reduces solution size and improves full-load efficiency by ≥5% vs. asynchronous designs. |
| Internal soft-start | 1.8 ms ramp time - prevents inrush current from tripping upstream fuses or causing input rail collapse during cold-start. |
| Hiccup-mode short-circuit protection | 135 ms shutdown interval - limits average power dissipation to <100 mW during sustained fault, preventing thermal runaway. |
| Pre-biased output startup | Supports hot-plug applications - allows safe turn-on even when output capacitor is pre-charged to target voltage. |
| Frequency foldback | Down to ~133 kHz - maintains regulation at ultra-low VIN (e.g., 4.2 V) or ultra-high VIN (e.g., 36 V) without dropout or instability. |
Applications
| Camera Power Supply | On-Board Charger Auxiliary Rail |
|---|---|
Use Scenario: Powers CMOS image sensor and ISP in rear-view or surround-view camera modules operating from vehicle battery (9–16 V nominal).

Use Value: ±0.5% reference accuracy enables <±1% output tolerance across temperature; EN pin hysteresis prevents oscillation during battery voltage sag. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS560430YFQDBVRQ1 | Same package and specs but FPWM mode instead of PFM - constant 2.1 MHz frequency, no light-load frequency variation. | Better for noise-sensitive applications (e.g., audio amplifiers) where EMI filtering must remain fixed; lower light-load efficiency than PFM version. | Select when output voltage ripple <10 mVpp and constant frequency are mandatory, even at expense of 5–10% lower efficiency at 1 mA load. |
| LM61480QRTWRQ1 | Higher 3.5 A output current, 2.1 MHz, but larger WSON-10 package; includes spread-spectrum and enhanced EMI performance. | Used in higher-power domains (e.g., ADAS domain controller); not drop-in due to different pinout, thermal pad, and FB divider ratio. | Choose only when >600 mA is required or when automotive EMI compliance (CISPR 25 Class 5) must be met without additional shielding. |
Compared with TPS560430YFQDBVRQ1, the TPS560430YQDBVRQ1 delivers superior light-load efficiency but variable frequency; compared with LM61480QRTWRQ1, it offers minimal footprint and cost advantage for sub-600 mA applications without advanced EMI features.

FAQ
What is the minimum input voltage required for TPS560430YQDBVRQ1 to start switching?
The TPS560430YQDBVRQ1 has a rising undervoltage lockout (UVLO) threshold of 3.55 V to 4.00 V. It begins switching once VIN exceeds the upper threshold (typically 3.75 V) and remains active until VIN falls below the falling threshold (typically 3.45 V). This hysteresis prevents oscillation near the trip point. The device supports startup with pre-biased output, making it suitable for hot-swap scenarios in automotive systems.
Does TPS560430YQDBVRQ1 require external compensation components?
No, the TPS560430YQDBVRQ1 features fully internal compensation - no external RC network is needed for loop stability. This simplifies design, reduces bill-of-materials count, and minimizes PCB area. The internal compensation is optimized for standard output capacitor types (e.g., 22–47 µF ceramic) and inductor values (1–2.2 µH), enabling robust performance across typical automotive load profiles without tuning.
Can TPS560430YQDBVRQ1 operate with an output voltage lower than 1.0 V?
No - the TPS560430YQDBVRQ1 uses a fixed 1.000 V internal reference voltage and requires the feedback divider to set VOUT ≥ 1.0 V. The datasheet specifies minimum VOUT as 1.0 V, and operation below this level is neither characterized nor guaranteed. Attempting sub-1.0 V outputs risks regulation loss, increased output error, and potential instability due to reference buffer limitations.
What is the purpose of the CB pin on TPS560430YQDBVRQ1, and what capacitor value is recommended?
CB is the bootstrap capacitor terminal for the high-side MOSFET gate driver. It must be connected to the SW pin via a 100 nF X7R or X5R ceramic capacitor rated ≥16 V. This capacitor charges during low-side conduction and supplies the gate drive voltage needed to fully enhance the high-side FET. Using a smaller or lower-voltage capacitor risks insufficient gate drive, increased RDS(on), and thermal stress under heavy load.
How does hiccup-mode protection work in TPS560430YQDBVRQ1 during a short circuit?
When the FB voltage drops below 40% of the 1.0 V reference (i.e., <400 mV) for 256 consecutive cycles, the TPS560430YQDBVRQ1 enters hiccup mode: it shuts down for 135 ms (typical), then attempts restart. If the fault persists, the cycle repeats. This limits average power dissipation to safe levels (<100 mW), preventing thermal damage while allowing automatic recovery once the short is removed - critical for unattended automotive systems.
