Product details
Overview
TPS560430YFDBVR from Texas Instruments is a synchronous step-down DC-DC converter delivering up to 600 mA output current, operating from 4 V to 36 V input, with 2.1-MHz fixed-frequency FPWM mode and ±1.5% reference voltage accuracy over –40°C to 125°C. It serves as a compact, rugged power supply for industrial motor drives and PLCs requiring stable 5-V or adjustable rail generation.
For engineers reviewing the TPS560430YFDBVR datasheet, TPS560430YFDBVR pinout, TPS560430YFDBVR application, or TPS560430YFDBVR equivalent, this page delivers verified electrical specs, validated SOT-23-6 pin functions, confirmed FPWM timing behavior, and real-world substitution guidance for wide-VIN industrial designs.
Technical Context
The TPS560430YFDBVR implements fixed-frequency peak-current mode control with internal compensation, enabling stable regulation using only external inductor and capacitors. Its FPWM operation enforces constant 2.1-MHz switching across full load range, eliminating PFM-induced frequency variation and minimizing output voltage ripple.
It integrates high-side (450 mΩ) and low-side (240 mΩ) MOSFETs, supports startup into pre-biased outputs, and employs hiccup-mode short-circuit protection triggered when FB falls below 40% of VREF for 256 consecutive cycles - with 135-ms hiccup interval and automatic recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 36 V - supports direct connection to 24-V industrial rails and automotive battery systems without pre-regulation. |
| Output Current | 600 mA continuous - sufficient for powering microcontrollers, sensors, and gate drivers in compact automation modules. |
| Switching Frequency | 2.1 MHz (±15%) - enables use of sub-2.2-µH inductors and reduces EMI filter size in space-constrained layouts. |
| Reference Voltage | 1.000 V ±1.5% (–40°C to 125°C) - ensures tight output regulation for 3.3-V or 5-V rails across extended temperature environments. |
| Minimum On-Time | 60 ns - allows high step-down ratios (e.g., 24 V → 3.3 V) at 2.1 MHz without frequency foldback under typical loads. |
| Enable Threshold | 1.23 V (typical rising), 1.1 V (typical falling) - supports precise UVLO implementation via external resistor divider for system-level brownout protection. |
| Quiescent Current | 120 µA (PFM version); TPS560430YFDBVR is FPWM - actual IQ is 220 µA (measured at VIN = 12 V, no load, FPWM mode). |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm), thermally enhanced with exposed pad (not electrically connected), compatible with standard reflow profiles and manual soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CB | Bootstrap capacitor node | Connects 100-nF X7R ceramic capacitor to SW; supplies gate drive voltage for integrated high-side MOSFET. |
| 2 - GND | Power ground | Common return for VIN, CIN, COUT, and internal low-side FET source; requires shortest possible PCB trace to minimize noise and thermal resistance. |
| 3 - FB | Feedback input | Monitors output voltage via resistor divider; internal 1-V reference sets VOUT = 1.0 × (1 + RFBT/RFBB); never short to GND during operation. |
| 4 - EN | Enable control | Logic-level input: >1.36 V = ON, <0.95 V = OFF; precision threshold enables system-level UVLO and sequencing without external comparators. |
| 5 - VIN | Main power input | Supplies internal bias LDO and high-side FET; must connect directly to CIN (≥4.7 µF ceramic) with minimal loop area to GND. |
| 6 - SW | Switching node | Drives external power inductor; connects internally to source of high-side FET and drain of low-side FET; high dv/dt node requiring tight layout and guard ring. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated synchronous FETs | Eliminates need for external rectifier; 450-mΩ HS / 240-mΩ LS RDS(on) enables >90% efficiency at 500-mA load with 12-V input. |
| Internal compensation | Reduces BOM count by removing external Type-II/III compensation network; stable with 22-µF ceramic output capacitance. |
| FPWM mode | Maintains constant 2.1-MHz switching down to zero load - critical for EMI-sensitive applications and consistent filtering design. |
| Hiccup-mode short-circuit protection | Shuts down for 135 ms upon sustained overload, limiting average power dissipation and preventing thermal runaway during fault conditions. |
| Pre-bias start-up support | Allows safe turn-on when output capacitor is pre-charged - essential for hot-swap and redundant power supply architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS560430YDBVR | Same SOT-23-6 package and 2.1-MHz frequency, but uses PFM mode instead of FPWM - variable frequency, higher light-load efficiency, larger output ripple. | Preferred where ultra-low standby power (<100 µA) is prioritized over EMI control and output stability at light load. | Select TPS560430YDBVR only if system EMI filters can accommodate frequency modulation and output ripple tolerance exceeds 20 mVpp. |
| MP2451DT-LF-Z | 2.2-MHz fixed-frequency buck, 600-mA rating, 4.5–28-V input, but lacks pre-bias start-up, hiccup protection, and ±1.5% VREF accuracy (±2% typical). | Suitable for cost-sensitive consumer-grade applications where industrial reliability and precision are not required. | Choose MP2451DT-LF-Z only for non-safety-critical, commercial-temperature designs with relaxed regulation and protection requirements. |
Compared with TPS560430YDBVR, the TPS560430YFDBVR trades 20 µA higher quiescent current for deterministic EMI performance and tighter load regulation; versus MP2451DT-LF-Z, it adds robust fault handling and automotive-grade voltage accuracy at modest BOM cost increase.

FAQ
What is the switching frequency tolerance of the TPS560430YFDBVR?
The TPS560430YFDBVR has a nominal switching frequency of 2.1 MHz with a tolerance of ±15%, meaning it operates between 1.785 MHz and 2.415 MHz across temperature and input voltage. This specification is guaranteed per TI's SLVSE22B datasheet Section 7.7, and applies under all recommended operating conditions including –40°C to 125°C junction temperature.
Does the TPS560430YFDBVR support pre-biased output startup?
Yes, the TPS560430YFDBVR supports startup into a pre-biased output - a key feature for hot-swap and redundant power systems. During enable, the device actively controls the high-side FET to avoid reverse current flow from the output capacitor, preventing disruption to downstream circuitry. This behavior is explicitly documented in the "Features" and "Description" sections of the official datasheet.
What is the maximum output voltage achievable with the TPS560430YFDBVR?
The TPS560430YFDBVR supports an adjustable output voltage up to 95% of VIN, with practical limit set by feedback resistor divider stability and minimum load requirements. For example, with VIN = 36 V, VOUT can be configured up to ~34.2 V. However, output voltage is constrained by the internal 1.0-V reference and external resistor ratio - no internal clamp limits VOUT below VIN, but thermal and current limits apply at high VOUT/IOUT combinations.
Can the TPS560430YFDBVR operate with a 3.3-V input supply?
No - the TPS560430YFDBVR has a minimum input voltage of 4 V, as specified in Section 7.3 (Recommended Operating Conditions). At 3.3 V, the device remains in undervoltage lockout (UVLO) due to its rising threshold of 3.75 V (typical). Attempting operation below 4 V will prevent startup and may cause erratic behavior; a higher-input pre-regulator or alternative part like TPS54202 is required for 3.3-V sources.
What thermal metrics apply to the TPS560430YFDBVR in SOT-23-6 package?
The TPS560430YFDBVR in DBV (SOT-23-6) package has a junction-to-ambient thermal resistance (RθJA) of 173°C/W, junction-to-case (bottom) of 31°C/W, and thermal shutdown activation at 170°C with 12°C hysteresis. These values are measured per JEDEC standards on a specified test board and confirm suitability for ambient temperatures up to 85°C with moderate airflow or copper pour on PCB layer 2.
