Product details
Overview
TPS54561QDPRRQ1 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 87-mΩ high-side MOSFET, Eco-mode™ pulse-skipping control, and 152-µA quiescent current. It delivers regulated 0.8-V to 58.8-V output in compact 4-mm × 4-mm WSON-10 package for vehicle accessories, USB charging ports, and 12-V/24-V automotive power systems.
For engineers reviewing the TPS54561QDPRRQ1 datasheet, TPS54561QDPRRQ1 pinout, TPS54561QDPRRQ1 application, or TPS54561QDPRRQ1 equivalent, key selection criteria include its 100-kHz–2.5-MHz adjustable switching frequency, internal 0.8-V ±1% reference, power-good (PWRGD) open-drain output, RT/CLK synchronization capability, and BOOT-recharge FET enabling low-dropout operation near 100% duty cycle.
Technical Context
The TPS54561QDPRRQ1 implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation above 50% duty cycle. Its error amplifier (gm = 350 µS typical) drives the COMP pin to regulate FB voltage at 0.8 V, while cycle-by-cycle current limiting (7.5-A typical) and thermal shutdown (176°C) provide robust overload protection.
It supports dual operating modes via the RT/CLK pin: resistor-programmed frequency (100 kHz–2.5 MHz) or external clock synchronization (160 kHz–2.3 MHz), with PLL lock-in time of 78 µs. The integrated BOOT recharge FET enables continuous operation down to dropout conditions, and the SS/TR pin provides programmable soft-start and tracking for sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QPWPRQ1 | 4.5–65-V input, 0.6-A max, 1-MHz fixed freq, no Eco-mode, higher RDS(on) (220 mΩ) | Better suited for ultra-low-IQ (<15 µA) always-on sensing nodes, not 5-A loads | Select when lower cost and smaller solution size outweigh need for 5-A output and pulse-skipping efficiency. |
| TPS54361QDPRRQ1 | Same family, 3.5-A output, identical pinout/package, same features and AEC-Q100 Grade 1 rating | Direct drop-in replacement where 3.5-A output suffices; shares layout, BOM, and firmware | Choose when full 5-A capability is unnecessary-reduces thermal margin requirements and simplifies thermal design. |
Compared with LM5164QPWPRQ1, TPS54561QDPRRQ1 delivers 7× higher output current and Eco-mode efficiency at light loads but requires larger magnetics. Versus TPS54361QDPRRQ1, it offers 43% higher current rating in identical footprint, enabling design reuse with only inductor and output capacitor upgrades.

FAQ
What is the maximum input voltage the TPS54561QDPRRQ1 can withstand during load dump events?
The TPS54561QDPRRQ1 is rated to survive ISO 7637 load dump pulses up to 65 V on the VDD pin. Its absolute maximum input voltage rating is 65 V, and it operates continuously from 4.5 V to 60 V. This makes TPS54561QDPRRQ1 suitable for 12-V and 24-V automotive systems where transient overvoltage protection is critical without external TVS clamping in many cases.
Does the TPS54561QDPRRQ1 require an external bootstrap diode?
No, the TPS54561QDPRRQ1 integrates a BOOT recharge FET, eliminating the need for an external bootstrap diode. A 0.1-µF ceramic capacitor (X7R/X5R, ≥10 V) between BOOT and SW is sufficient. This integration reduces component count, improves reliability, and enables low-dropout operation approaching 100% duty cycle-key for TPS54561QDPRRQ1 in high-input, low-output voltage applications.
How does the Eco-mode™ operation affect light-load efficiency in the TPS54561QDPRRQ1?
TPS54561QDPRRQ1's Eco-mode™ uses pulse-skipping to disable switching cycles when output current falls below ~25 mA (depending on inductor value), reducing gate-drive and switching losses. At 100-mA load, this achieves >85% efficiency-significantly higher than forced-PWM alternatives. The 152-µA quiescent current and 2-µA shutdown current further extend battery life in always-on vehicle modules powered by TPS54561QDPRRQ1.
Can the TPS54561QDPRRQ1 synchronize to an external clock, and what are the timing requirements?
Yes, the TPS54561QDPRRQ1 supports external clock synchronization via the RT/CLK pin. When driven with a clean square wave (160–2300 kHz), the internal PLL locks within 78 µs. Minimum CLK pulse width is 15 ns. Synchronization eliminates beat frequencies in multi-rail systems and enables EMI reduction through spread-spectrum clocking-critical for TPS54561QDPRRQ1 in noise-sensitive ADAS and infotainment applications.
What is the function of the SS/TR pin on the TPS54561QDPRRQ1, and how is it used for power sequencing?
The SS/TR pin on TPS54561QDPRRQ1 controls soft-start ramp rate (via external capacitor) and enables voltage tracking (via resistor divider). For sequencing, connect SS/TR of a secondary TPS54561QDPRRQ1 to the output of a primary regulator-this forces the secondary to follow the primary's rise time. During faults, TPS54561QDPRRQ1 actively discharges SS/TR to ensure repeatable restart behavior, improving system reliability in automotive environments.
