Product details
Overview
TPS62A01QDRLRQ1 from Texas Instruments is an AEC-Q100 Grade 1 synchronous step-down DC-DC converter delivering up to 1 A output current, operating from 2.5 V to 5.5 V input, with adjustable 0.6 V to VIN output voltage, 2.4 MHz fixed switching frequency, and <25 µA quiescent current - deployed in automotive front camera power rails.
For engineers reviewing the TPS62A01QDRLRQ1 datasheet, TPS62A01QDRLRQ1 pinout, TPS62A01QDRLRQ1 application, or TPS62A01QDRLRQ1 equivalent, key selection criteria include automotive-grade thermal robustness (–40°C to +125°C), integrated power-good signaling, 100% duty-cycle low-dropout operation, and SOT-563 package compatibility for space-constrained ADAS modules.
Technical Context
The TPS62A01QDRLRQ1 employs peak-current-mode control with adaptive off-time modulation, enabling stable 2.4 MHz PWM operation across input/output variations while maintaining constant frequency behavior. Its internal 600 mV feedback reference and 1.5% accuracy over –40°C to +150°C ensure precise regulation under wide thermal conditions.
It integrates high-side (100 mΩ) and low-side (67 mΩ) MOSFETs, supports power-save mode at light loads, and features HICCUP short-circuit protection triggered after 32 overcurrent events. The device enters 100% duty cycle mode below dropout threshold and provides active output discharge via the SW pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports direct connection to automotive 3.3 V or 5 V rails without pre-regulation. |
| Output Current | 1 A continuous - sufficient for powering image sensors and ISP cores in front-camera modules. |
| Switching Frequency | 2.4 MHz - enables use of small 1 µH inductors and compact ceramic capacitors for high-density layouts. |
| Quiescent Current | <25 µA - minimizes standby power loss in always-on automotive vision systems. |
| Feedback Accuracy | ±1.5% from –40°C to +150°C - ensures stable core voltage for processors under full automotive temperature range. |
| Thermal Shutdown | 170°C with 20°C hysteresis - protects against sustained overload in sealed ECU enclosures. |
| Power-Good Delay | Rising edge: 10 µs, falling edge: 35 µs - enables precise sequencing with downstream logic or FPGAs. |
Pinout & Package
TPS62A01QDRLRQ1 is housed in a 1.60 mm × 1.60 mm SOT-563 (DRL) package with 6 pins, optimized for thermal performance and PCB area efficiency in automotive camera modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Primary return path for power stage and control circuitry; must be connected to low-impedance ground plane. |
| SW (Pin 2) | Switch node | Connects to inductor and internal HS/LS FETs; high dv/dt node requiring tight layout and minimal trace length. |
| VIN (Pin 3) | Input supply | Accepts 2.5–5.5 V; requires local 4.7 µF ceramic decoupling placed adjacent to pin. |
| EN (Pin 4) | Enable control | Active-high logic input; 1.2 V min high threshold allows direct MCU GPIO drive without level shift. |
| FB (Pin 5) | Feedback input | Monitors output via resistor divider; 600 mV reference enables precise adjustable VOUT down to 0.6 V. |
| PG (Pin 6) | Power-good open-drain | Signals valid regulation; requires external pullup ≤5.5 V; used for rail sequencing in multi-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets automotive ECU reliability requirements. |
| 100% duty-cycle mode | Enables ultra-low dropout operation when VIN ≈ VOUT - critical for battery-backed or low-VIN camera rails. |
| Internal soft-start (1 ms) | Prevents inrush current during power-up - avoids brownout on shared 5 V supplies in surround-view ECUs. |
| Active output discharge | Drains residual charge from output capacitor via SW pin - ensures fast, controlled shutdown for safety-critical vision systems. |
| HICCUP short-circuit protection | Auto-retries after 100 µs delay upon 32 consecutive overcurrent events - prevents latch-up during sensor cable faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62A01AQDRLRQ1 | Forced PWM (FPWM) mode only - no automatic PSM transition; higher light-load IQ (~35 µA). | Better ripple/noise predictability in noise-sensitive radar or audio subsystems. | Select when deterministic switching frequency is required over full load range. |
| LM61480QRNRRQ1 | 3.5-A rating, 2.1-MHz switching, larger 12-pin WSON package; higher RDS(on) (29/15 mΩ). | Suitable for higher-current ADAS domain controllers where 1-A limit is insufficient. | Choose when >1 A output or enhanced thermal margin is needed; not pin-compatible. |
Compared with TPS62A01AQDRLRQ1, the TPS62A01QDRLRQ1 offers superior light-load efficiency via PSM but less predictable frequency behavior; versus LM61480QRNRRQ1, it delivers identical automotive qualification in half the footprint and cost, albeit at lower current capacity.

FAQ
What is the maximum output current capability of the TPS62A01QDRLRQ1?
The TPS62A01QDRLRQ1 delivers up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 150°C, proper PCB thermal design). Its integrated 100 mΩ high-side and 67 mΩ low-side MOSFETs enable this rating in the compact SOT-563 package. Derating applies above 85°C ambient; consult thermal metrics (RθJA = 154.2°C/W) for system-level design.
Does the TPS62A01QDRLRQ1 support power sequencing with other rails?
Yes, the TPS62A01QDRLRQ1 includes a dedicated open-drain power-good (PG) output that asserts high when VOUT reaches 96% of target and deasserts low at 93.5%. With configurable external pullup, PG enables precise start-up and fault sequencing with FPGAs, microcontrollers, or other DC-DC converters in multi-rail automotive systems like surround-view ECUs.
How does the TPS62A01QDRLRQ1 handle input voltage drop during cold-crank conditions?
The TPS62A01QDRLRQ1 supports input voltages as low as 2.5 V and features 100% duty-cycle operation, allowing it to maintain regulation even when VIN approaches VOUT. During cold-crank (e.g., VIN dipping to 2.5 V), it sustains 1.8 V output by fully turning on the high-side FET - a key advantage over non-100% buck regulators that would drop out.
Is the TPS62A01QDRLRQ1 compatible with ceramic output capacitors?
Yes, the TPS62A01QDRLRQ1 is optimized for low-ESR ceramic output capacitors. The datasheet recommends X7R dielectric types (e.g., 22 µF, 0805) for stability and low ripple. Its current-mode control architecture ensures robust loop stability with typical 10–22 µF ceramic values and 1 µH inductors - eliminating need for electrolytic or tantalum alternatives.
What protection features are built into the TPS62A01QDRLRQ1?
The TPS62A01QDRLRQ1 integrates undervoltage lockout (UVLO), thermal shutdown (170°C with 20°C hysteresis), HICCUP-mode short-circuit protection, and overcurrent limiting (1.5–1.8 A peak). It also provides active output discharge via the SW pin and internal soft-start to prevent inrush - collectively meeting stringent automotive functional safety expectations without external components.
