Product details
Overview
TPS54560QDDAQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 4.5-V to 60-V input, 5-A synchronous step-down DC-DC converter with integrated 92-mΩ high-side MOSFET, Eco-Mode™ pulse-skipping for light-load efficiency, adjustable 100-kHz to 2.5-MHz switching frequency, and internal 0.8-V ±1% voltage reference. It delivers regulated power in vehicle accessories, ADAS, and industrial 12/24/48-V systems.
For engineers reviewing the TPS54560QDDAQ1 datasheet, TPS54560QDDAQ1 pinout, TPS54560QDDAQ1 application, or TPS54560QDDAQ1 equivalent, key selection criteria include input voltage range (4.5–60 V), output current capability (5 A continuous), thermal performance in HSOIC PowerPAD package, Eco-Mode quiescent current (146 µA), and synchronization support via RT/CLK pin.
Technical Context
The TPS54560QDDAQ1 implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation above 50% duty cycle. Its PLL-based RT/CLK interface supports both resistor-programmed frequency (100–2500 kHz) and external clock synchronization (160–2300 kHz).
It integrates BOOT capacitor recharge logic, low-dropout operation enabled by internal bootstrap FET, overvoltage protection (OVP) with 106% trip threshold, and cycle-by-cycle current limiting with 7.5-A typical current limit threshold. Thermal shutdown activates at 176°C with 12°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 60 V - Supports automotive load dump (65 V transient) and wide industrial input rails. |
| Output Current | 5 A continuous - Delivers full rated current with proper PCB thermal design (RθJB = 23.4°C/W). |
| Switching Frequency | 100 kHz to 2.5 MHz - Adjustable via RT resistor or external clock; enables optimization of efficiency vs. size. |
| Quiescent Current | 146 µA in Eco-Mode - Enables >90% efficiency at 10-mA loads; critical for always-on automotive modules. |
| Reference Voltage | 0.8 V ±1% - Sets output accuracy; used with FB resistor divider for precise output regulation. |
| High-Side RDS(on) | 92 mΩ typical at VBOOT–VSW = 6 V - Defines conduction loss and thermal rise at full load. |
| UVLO Threshold | 4.3 V rising, 4.1 V falling - Internally fixed; adjustable via EN pin resistor divider for custom start/stop behavior. |
| Thermal Shutdown | 176°C with 12°C hysteresis - Protects die during overload or poor heatsinking; ensures safe recovery before restart. |
Pinout & Package
TPS54560QDDAQ1 uses an 8-pin HSOIC PowerPAD™ package (3.90 mm × 4.89 mm) with exposed thermal pad electrically connected to GND. The PowerPAD must be soldered to a large PCB copper area for thermal performance (RθJB = 23.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT | Bootstrap supply node | Drives high-side MOSFET gate; requires 0.1-µF ceramic cap to SW; monitored for UVLO to prevent shoot-through. |
| VIN | Main input supply | Accepts 4.5–60 V; powers internal circuitry and high-side driver; withstands 65-V transients per ISO 7637. |
| EN | Enable & UVLO control | Pull below 1.2 V to disable; internal 1.2-µA pull-up enables floating operation; supports resistor-divider UVLO adjustment. |
| RT/CLK | Frequency programming/sync | Resistor-to-GND sets frequency (100–2500 kHz); pulled above 1.55 V to enter high-Z clock sync mode (160–2300 kHz). |
| FB | Feedback input | Inverting input of error amplifier; compares output voltage (via resistor divider) to 0.8-V reference for regulation. |
| COMP | Error amplifier output | Drives PWM comparator; connects to external compensation network (capacitor + RC series) for loop stability. |
| GND | Power and signal ground | Common return for VIN, SW, COMP, FB; must connect to thermal pad for thermal and electrical integrity. |
| SW | Switching node | Source of internal high-side MOSFET; connects to external inductor and catch diode/FET; high dv/dt node requiring careful layout. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-Mode™ pulse-skipping | Reduces no-load IQ to 146 µA while maintaining regulation-enables >92% efficiency at 10 mA output. |
| Integrated BOOT recharge FET | Enables near-100% duty cycle operation without external diode; supports low dropout (VOUT ≈ VIN – 0.3 V). |
| Adjustable UVLO with hysteresis | EN pin supports custom start/stop thresholds using two resistors; adds 3.4-µA hysteresis current for stable turn-on/off. |
| Overvoltage protection (OVP) | Shuts off high-side MOSFET if VOUT exceeds 106% of setpoint; prevents damage to downstream 5-V or 3.3-V ICs. |
| Internal soft-start | 2.1-ms typical ramp time at 500 kHz; eliminates inrush current and output overshoot during power-up. |
| Frequency foldback | Reduces fSW during startup and overload to maintain control of inductor current and avoid saturation. |

FAQ
What is the maximum input voltage the TPS54560QDDAQ1 can withstand during load dump events?
The TPS54560QDDAQ1 survives load dump pulses up to 65 V per ISO 7637. Its absolute maximum VIN rating is 65 V, and it operates continuously from 4.5 V to 60 V. This makes TPS54560QDDAQ1 suitable for direct connection to automotive batteries without additional front-end clamping in most cases.
Does the TPS54560QDDAQ1 require an external bootstrap diode?
No, the TPS54560QDDAQ1 integrates a bootstrap recharge FET, eliminating the need for an external bootstrap diode. A 0.1-µF ceramic capacitor between BOOT and SW is required. This integration reduces BOM count and improves reliability in high-vibration automotive environments where discrete diodes may fail.
How does Eco-Mode™ affect light-load efficiency in the TPS54560QDDAQ1?
Eco-Mode™ in the TPS54560QDDAQ1 reduces switching activity at light loads, lowering quiescent current to 146 µA and enabling >90% efficiency at 10-mA output. It operates by clamping COMP at 600 mV and inhibiting the high-side MOSFET until output droop triggers resumption-critical for always-on automotive modules like GPS or telematics.
Can the TPS54560QDDAQ1 synchronize to an external clock, and what are the valid frequency ranges?
Yes, the TPS54560QDDAQ1 synchronizes to an external clock via the RT/CLK pin when pulled above 1.55 V. Valid CLK input frequencies range from 160 kHz to 2.3 MHz, with minimum pulse width of 15 ns. The internal PLL locks within 78 µs, ensuring deterministic timing alignment for noise-sensitive multi-rail systems.
What thermal performance can be expected from the TPS54560QDDAQ1 in its HSOIC PowerPAD package?
In the 8-pin HSOIC PowerPAD package, the TPS54560QDDAQ1 achieves RθJB = 23.4°C/W (junction-to-board) with standard 2-oz copper and 6 thermal vias under the pad. At 5-A load and 12-V input, typical junction rise is ~35°C above board temperature-enabling full-rated operation without forced air in automotive cabin or industrial enclosures.
