Product details
Overview
TPS62590TDRVRQ1 from Texas Instruments is an automotive-grade synchronous step-down DC-DC converter delivering up to 1 A output current, operating at a fixed 2.25 MHz switching frequency, with input voltage range 2.5 V to 6 V and adjustable output voltage from 0.75 V to VIN. It powers infotainment head units and ADAS front cameras requiring compact, high-efficiency regulation under low-quiescent-current constraints.
For engineers reviewing the TPS62590TDRVRQ1 datasheet, TPS62590TDRVRQ1 pinout, TPS62590TDRVRQ1 application, or TPS62590TDRVRQ1 equivalent, key selection considerations include its 15 µA typical quiescent current in power-save mode, 2.25-MHz fixed-frequency PWM operation, 100% duty-cycle low-dropout capability, and AEC-Q100 qualification for automotive ambient temperatures up to +105°C.
Technical Context
The TPS62590TDRVRQ1 employs voltage-mode control with input-voltage feed-forward for fast line/load regulation and supports automatic transition between PFM (power-save) and PWM modes based on load current. Its integrated high-side/low-side MOSFETs feature 250 mΩ and 190 mΩ typical RDS(on), enabling efficient operation across 2.5–6 V input rails.
It implements dynamic voltage positioning (1% above nominal VOUT) in PFM mode to suppress load-step undershoot, includes undervoltage lockout (1.85 V falling threshold), thermal shutdown at 140°C, and soft-start with 250 µs ramp-up time. The MODE pin selects between forced PWM (low noise) and auto-PFM/PWM (high light-load efficiency).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | Up to 1000 mA - supports single-rail powering of SoCs, FPGAs, and image sensors in automotive modules. |
| Input Voltage Range | 2.5 V to 6 V - compatible with 3.3 V, 5 V, and battery-backed automotive rails including partially discharged 12 V systems via LDO pre-regulation. |
| Switching Frequency | 2.25 MHz fixed - enables use of small 2.2 µH inductors and 10 µF ceramic output capacitors for <4 mm² solution size. |
| Quiescent Current | 15 µA typical in power-save mode - extends battery runtime in always-on ADAS subsystems without compromising wake-up responsiveness. |
| Output Voltage Accuracy | ±2.5% in PWM mode - ensures stable core voltage for processors and memory interfaces under varying thermal and load conditions. |
| Duty Cycle | 100% - maintains regulation down to VIN ≈ VOUT + IOUT × (RDS(on) + LDCR), maximizing usable battery voltage range in portable automotive devices. |
| Thermal Shutdown | 140°C junction temperature - protects against sustained overload or poor PCB thermal design while allowing full rated operation at +105°C ambient. |
Pinout & Package
TPS62590TDRVRQ1 is housed in a thermally enhanced 2-mm × 2-mm, 6-pin SON package (DRV) with exposed thermal pad soldered to PCB ground for optimal heat dissipation (RθJB = 37.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SW | Switch node | Connects internal high-side/low-side MOSFETs to external inductor; requires low-inductance layout to minimize EMI and switching losses. |
| 2 MODE | Mode control input | Pull to GND for auto PFM/PWM transition; pull to VIN for forced fixed-frequency PWM-critical for noise-sensitive analog/RF sections. |
| 3 FB | Feedback input | Monitors output voltage via external resistor divider; open for fixed-output variants; sets VOUT = 0.6 V × (1 + R1/R2). |
| 4 EN | Enable input | Active-high logic control; drives low to enter <0.5 µA shutdown state-enables precise power sequencing in multi-rail systems. |
| 5 VIN | Power input | Accepts 2.5–6 V supply; requires 10 µF ceramic input capacitor close to pin for high-frequency decoupling and stability. |
| 6 GND | Ground reference | Primary return path for power and signal; must be connected to thermal pad for thermal and electrical integrity. |
| Thermal Pad | Thermal & electrical ground | Exposed copper pad beneath package; must be soldered to large PCB ground plane to achieve specified RθJB and prevent thermal derating. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C TJ) - validated for engine bay, dashboard, and ADAS camera module deployment. |

| Voltage positioning | 1% overregulation in PFM mode - provides margin to absorb 100 mA–1 A load steps without undershoot in infotainment displays. |
| Short-circuit protection | Integrated current-limit comparators with 1.19–1.78 A trip threshold - prevents damage during output faults without external circuitry. |
| Low-dropout operation | 100% duty cycle support - extends functional battery life by regulating down to VIN = VOUT + IOUT × (250 mΩ + LDCR). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62560QDSGRQ1 | Same 2.25 MHz frequency and AEC-Q100 Grade 1 rating, but lower 600 mA output current and 2.7–6 V input range. | Suitable for lower-power MCU or sensor rails where 1 A is unnecessary; lacks 100% duty-cycle mode below 2.7 V. | Select when space-constrained automotive sensor nodes require identical footprint but reduced current capability and cost. |
| LM61480-Q1 | Higher 8 A output, 2.1 MHz frequency, and wider 3–36 V input range; uses current-mode control and requires external compensation. | Targeted at high-power ADAS domain controllers or gateway ECUs-not drop-in compatible due to different pinout, control architecture, and external component requirements. | Choose for next-generation platforms scaling beyond 1 A, accepting larger solution size and added design complexity for higher integration. |
Compared with TPS62590TDRVRQ1, TPS62560QDSGRQ1 offers footprint compatibility and identical control features at reduced current, while LM61480-Q1 delivers scalable power at the cost of increased BOM count and layout sensitivity-making TPS62590TDRVRQ1 optimal for cost- and size-sensitive 1-A automotive point-of-load applications.

FAQ
What is the maximum output current capability of the TPS62590TDRVRQ1?
The TPS62590TDRVRQ1 delivers up to 1000 mA of continuous output current under recommended operating conditions (TA ≤ +105°C, proper thermal layout). Peak current is internally limited to approximately 1.19–1.78 A depending on junction temperature and input voltage. Derating applies above +85°C ambient unless PCB thermal design meets RθJB = 37.2°C/W specification.
How does the MODE pin affect TPS62590TDRVRQ1 operation in automotive applications?
The MODE pin on the TPS62590TDRVRQ1 selects between two distinct operating modes: pulled low (GND) enables automatic PFM/PWM transition for peak light-load efficiency, while pulled high (VIN) forces fixed-frequency PWM for predictable EMI and low-noise performance. In ADAS camera modules, forcing PWM avoids beat frequencies with image sensor clocks; in always-on telematics, PFM mode minimizes standby current.
Can TPS62590TDRVRQ1 operate with input voltage below 2.5 V?
No-the absolute minimum input voltage for functional operation of the TPS62590TDRVRQ1 is 2.5 V per recommended conditions, and the undervoltage lockout (UVLO) disables switching below ~1.85 V (falling threshold). Operation below 2.5 V violates specifications and may cause unregulated output or erratic behavior; it is not supported for cold-cranking or backup battery scenarios without upstream pre-regulation.
What is the purpose of the thermal pad on the TPS62590TDRVRQ1 DRV package?
The exposed thermal pad on the TPS62590TDRVRQ1's 2-mm × 2-mm SON package must be soldered to a PCB ground plane to achieve the specified RθJB = 37.2°C/W. Without proper thermal pad connection, junction temperature rises significantly-potentially triggering thermal shutdown at <500 mA load-and output voltage accuracy degrades due to internal reference drift. TI recommends ≥4 thermal vias under the pad.
Does TPS62590TDRVRQ1 support adjustable output voltage, and how is it set?
Yes-TPS62590TDRVRQ1 supports adjustable output voltage from 0.75 V to VIN using an external resistor divider on the FB pin. The internal reference is 600 mV, so VOUT = 0.6 V × (1 + R1/R2). For example, 182 kΩ (R1) and 820 kΩ (R2) set 3.3 V output. Fixed-output variants exist, but TPS62590TDRVRQ1 is the adjustable version requiring external feedback network placement per layout guidelines.
