Product details
Overview
TPS568230 from Texas Instruments is an 8-A synchronous step-down voltage regulator with integrated 19.5-mΩ high-side and 9.5-mΩ low-side MOSFETs, operating from 4.5 V to 18 V input and delivering 0.6 V to 7 V output. It employs D-CAP3™ control for fast transient response without external compensation and supports FCCM, OOA, and Advanced Eco-Mode™ for light-load efficiency optimization in point-of-load power delivery for networking and industrial systems.
For engineers reviewing the TPS568230 datasheet, TPS568230 pinout, TPS568230 application, or TPS568230 equivalent, key selection criteria include its 3.0-mm × 3.0-mm HotRod™ QFN package, 600/800/1-MHz selectable switching frequency, 0.6-V ±1% reference accuracy, ultra-low quiescent current (105 µA), and integrated power-good and output discharge functions.
Technical Context
The TPS568230 implements D-CAP3™ adaptive on-time control with internal ripple injection, enabling stable operation with ultra-low-ESR ceramic or polymer output capacitors and eliminating need for external compensation. Its cycle-by-cycle valley-current overcurrent protection uses temperature-compensated low-side RDS(on) sensing, while ULQ™ mode maintains 2-µA shutdown current for battery-backed standby.
Thermal protection triggers at 150°C with 20°C hysteresis; UVLO activates at 4.4 V (wake-up) and 3.8 V (shutdown) with 0.4 V hysteresis. The MODE pin selects between FCCM (fixed-frequency, low ripple), OOA (>25 kHz audible avoidance), and Advanced Eco-Mode™ (high-efficiency discontinuous conduction).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 18 V - supports common industrial and telecom rails including 5 V, 12 V, and 15 V inputs. |
| Output Current | 8 A continuous - enables single-chip point-of-load regulation for FPGA, ASIC, or SoC core supplies. |
| Feedback Reference | 0.6 V ±1% at 25°C - ensures tight output voltage accuracy across load and temperature for precision regulation. |
| Switching Frequency | 600 / 800 / 1000 kHz - selectable via MODE pin resistor divider; higher frequencies reduce inductor size but increase switching loss. |
| Quiescent Current | 105 µA at no load - extends battery life in always-on or low-power standby modes (ULQ™ feature). |
| Package | 20-pin VQFN (RJE), 3.0 mm × 3.0 mm - HotRod™ construction minimizes parasitic inductance for high-frequency stability and thermal performance. |
| Junction Temperature | –40°C to +125°C - rated for industrial and embedded environments with full electrical specs across range. |
Pinout & Package
TPS568230 is housed in a 20-pin VQFN (RJE) package measuring 3.0 mm × 3.0 mm with exposed thermal pad. The HotRod™ construction places power pins (VIN, SW, GND) on perimeter for low-inductance layout and enhanced thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST | Bootstrap supply | Connects 0.1-μF capacitor to SW; powers high-side gate driver - critical for proper high-side FET turn-on above VIN. |
| VIN (2,3,4,5) | Main input supply | Accepts 4.5–18 V; multiple pins reduce IR drop and improve decoupling - requires local 10-μF ceramic input capacitor. |
| SW (6,19,20) | Switch node | Connects to inductor; carries high di/dt switching current - must be short, wide, and thermally anchored to minimize EMI and losses. |
| GND / AGND (7,8,18,Pad,13) | Power & analog ground | Separate AGND (pin 13) for feedback reference; all GND pins tied to solid thermal pad - essential for noise immunity and thermal management. |
| FB (14) | Feedback input | Monitors output via resistor divider; 0.6-V reference sets VOUT = 0.6 × (1 + R1/R2) - accuracy directly impacts regulation tolerance. |
| EN (12) | Enable control | Digital input; 1.21–1.4 V high threshold; internal pull-down disables converter if floating - enables sequencing and system-level power control. |
| MODE (15) | Operation mode select | Resistor divider from VCC to AGND configures FCCM/OOA/Eco-Mode™ - determines light-load behavior and audible noise profile. |
| SS (11) | Soft-start control | External capacitor sets soft-start time beyond internal 1.3 ms - prevents inrush current and output overshoot during startup. |
| PGOOD (9) | Power-good indicator | Open-drain output asserted low if VOUT < 90% or > 110% of target, or during fault - used for system enable sequencing and fault reporting. |
| VCC (17) | Internal LDO output | 5.0-V ±1.5% regulated supply for internal circuitry; bypass with 1-μF capacitor - powers gate drivers and control logic independently of VIN. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP3™ control architecture | Enables stable operation with zero external compensation components and compatibility with ultra-low-ESR ceramic or polymer output capacitors. |
| ULQ™ ultra-low quiescent current | 105 µA operating current and 2 µA shutdown current - preserves battery energy in always-on or sleep-mode applications. |
| Selectably optimized light-load modes | FCCM (tight ripple), OOA (>25 kHz), or Advanced Eco-Mode™ - allows trade-off between efficiency, noise, and transient response per system requirement. |
| Integrated protection suite | Cycle-by-cycle overcurrent, non-latched thermal shutdown (150°C), output over/under-voltage, and UVLO - eliminates need for discrete protection circuitry. |
| Built-in output discharge | 420-Ω internal discharge path from SW to GND - safely discharges output capacitance during shutdown, preventing backfeed or latch-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS568215RJER | Same 3.0-mm × 3.0-mm RJE package and D-CAP3™ control, but rated for 6-A continuous output and lower 16-mΩ/8-mΩ RDS(on). | Suitable for lower-current applications where thermal margin or cost optimization is prioritized over 8-A headroom. | Choose TPS568215RJER when design load stays ≤6 A and board space or BOM cost is constrained. |
| MP2384CGG-Z | Monolithic 8-A buck with 12-V max input (vs. 18 V), fixed 600-kHz frequency, no MODE pin or OOA mode, and 0.8-V reference (vs. 0.6 V). | Limited to lower-input-voltage systems; lacks light-load mode flexibility and ultra-low-IQ capability (IQ = 300 µA typical). | Consider MP2384CGG-Z only for cost-sensitive 5–12-V input designs where advanced light-load features are unnecessary. |
Compared with TPS568215RJER and MP2384CGG-Z, the TPS568230 uniquely combines 18-V input capability, 8-A rating, ULQ™ current, and three selectable light-load modes - making it optimal for high-flexibility, wide-input industrial and networking point-of-load designs.

FAQ
What is the maximum duty cycle supported by the TPS568230?
The TPS568230 supports up to 90% duty operation via internal TON extension when VIN/VOUT < 1.6. This enables high-step-down ratios such as 12 V → 1.2 V (10:1) without external circuitry, improving light-load transient response and efficiency in high-input, low-output applications like CPU core supplies.
How does the MODE pin configure light-load behavior in the TPS568230?
The MODE pin on the TPS568230 accepts a resistor divider from VCC to AGND to select Forced Continuous Conduction Mode (FCCM), Out-of-Audio™ (OOA) Mode, or Advanced Eco-Mode™. Each setting alters switching behavior: FCCM maintains fixed frequency for lowest ripple, OOA avoids audible noise by staying >25 kHz, and Eco-Mode™ skips pulses to maximize light-load efficiency - all without changing external components.
Does the TPS568230 require external compensation components?
No, the TPS568230 does not require external compensation components due to its D-CAP3™ control architecture. The internal adaptive on-time loop with ripple injection provides inherent stability across a wide range of output capacitors - including ultra-low-ESR ceramics and specialty polymer types - simplifying design and reducing bill-of-materials count.
What protection features are integrated into the TPS568230?
The TPS568230 integrates cycle-by-cycle valley-current overcurrent protection, non-latched thermal shutdown (150°C trip), output overvoltage (125% threshold) and undervoltage (60% threshold) detection, input UVLO (4.4 V wake-up), and built-in output discharge via a 420-Ω internal FET. These features eliminate need for discrete protection circuitry in most point-of-load implementations.
Can the TPS568230 operate with a 5-V input supply?
Yes, the TPS568230 operates with a minimum input voltage of 4.5 V, making it fully compatible with 5-V input rails. At VIN = 5 V, the device delivers regulated output down to 0.6 V with full 8-A capability, and VCC remains functional (minimum VIN for VCC regulation is 4.5 V, with VCC output dropping to 4.5 V at that limit).
