Product details
Overview
TPS61087QDRCRQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade boost DC-DC converter with integrated 3.2-A/0.13-Ω N-channel MOSFET, 2.5–6-V input range, 18.5-V max output, and selectable 650-kHz or 1.2-MHz switching frequency-used to power infotainment displays, ADAS sensors, and body control modules.
For engineers reviewing the TPS61087QDRCRQ1 datasheet, TPS61087QDRCRQ1 pinout, TPS61087QDRCRQ1 application, or TPS61087QDRCRQ1 equivalent, key selection criteria include its functional safety capability, external compensation flexibility, soft-start programmability via CSS, thermal shutdown (150°C), and wettable-flank VQFN-10 package for automotive-grade solder joint inspection.
Technical Context
The TPS61087QDRCRQ1 operates in current-mode control with quasi-constant frequency and adaptive OFF-time topology, enabling superior line/load transient response across automotive temperature ranges (–40°C to +125°C). Its externally compensated error amplifier (gm = 107 µA/V) and adjustable soft-start (via SS pin and 100-nF capacitor) support stable startup under varying load conditions.
Frequency selection is implemented via FREQ pin logic level: GND selects 650 kHz (optimized for efficiency), while IN selects 1.2 MHz (optimized for smaller magnetics and lower output ripple). The device enters pulse-skipping mode at light loads and supports CCM/DCM operation depending on load current and inductor value.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 6 V - supports direct connection to automotive battery (cold-crank down to 2.5 V) without pre-regulation |
| Max Output Voltage | 18.5 V - enables powering 12-V or 15-V rails from low-voltage sources (e.g., 5-V MCU supply) |
| Switch Current Limit | 3.2 A (min) - sustains ≥500 mA @ 15 V output with margin for transients and efficiency derating |
| Switching Frequency | Selectable 650 kHz or 1.2 MHz - allows trade-off between inductor size (3.3 µH @ 1.2 MHz) and efficiency (up to 92% @ 500 mA) |
| Feedback Reference | 1.238 V (±1.5%) - sets output voltage accuracy via external resistor divider (e.g., R1=200 kΩ, R2=18 kΩ for 15 V) |
| Quiescent Current | 75 µA (typ) - minimizes standby power loss in always-on automotive systems |
| Thermal Shutdown | 150°C (with 14°C hysteresis) - protects against sustained overload or poor PCB thermal design |
Pinout & Package
TPS61087QDRCRQ1 uses a 10-pin VSON (VQFN) package with 3.0 mm × 3.0 mm body and wettable flanks for automated optical inspection (AOI) of solder joints in automotive production.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COMP | Error amplifier output | Connects to external RC network (e.g., 100 kΩ + 820 pF) for loop compensation and stability optimization |
| 2 - FB | Feedback input | Senses output voltage via resistor divider; regulates output to 1.238 V reference |
| 3 - EN | Enable input | Active-high logic control: tie to VIN for always-on, or drive with MCU GPIO for sequencing |
| 4 - AGND | Analog ground | Reference for internal bias circuits; must be connected to PGND at single point near IC |
| 5 - PGND | Power ground | High-current return path for switch node; requires low-inductance copper pour under thermal pad |
| 6,7 - SW | Switch node | Drives external inductor and Schottky diode (e.g., SL22); handles peak currents up to 3.2 A |
| 8 - IN | Input supply | Accepts 2.5–6 V; requires local 1-µF ceramic bypass and bulk 2×10-µF input capacitance |
| 9 - FREQ | Frequency select | GND = 650 kHz, VIN = 1.2 MHz - determines inductor size, efficiency, and transient response |
| 10 - SS | Soft-start control | Charged by 10 µA current; 100-nF capacitor yields ~10-ms ramp time to limit inrush current |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM61480QRTWRQ1 | 4.5–36-V input, 3.5-A switch, fixed 2.1-MHz frequency, integrated compensation - no external COMP/SS required | Better suited for higher-input automotive systems (e.g., 12-V battery direct); lacks frequency select and soft-start adjustability | Choose when simplifying design with fewer external components outweighs need for frequency flexibility |
| TPS61282DYFFT | 2.7–5.5-V input, 2.5-A switch, 1.5-MHz fixed frequency, smaller 6-pin WSON - no FREQ/SS pins, no AEC-Q100 rating | Targeted at consumer portable electronics; not qualified for automotive temperature or reliability requirements | Consider only for non-automotive cost-sensitive designs where AEC-Q100 and extended temperature are unnecessary |
Compared with LM61480QRTWRQ1 and TPS61282DYFFT, the TPS61087QDRCRQ1 uniquely balances automotive qualification, frequency selectability, and external compensation - making it optimal for mid-range input (2.5–6 V) applications demanding design flexibility and functional safety support.

FAQ
What is the maximum output voltage supported by the TPS61087QDRCRQ1?
The TPS61087QDRCRQ1 supports a maximum output voltage of 18.5 V. This is achieved using an external resistor divider on the FB pin referenced to the internal 1.238-V bandgap. The device maintains regulation up to this voltage across its full input range (2.5 V to 6 V) and load conditions, provided thermal limits and switch current capability are respected.
How does the FREQ pin affect switching frequency and system performance in the TPS61087QDRCRQ1?
The FREQ pin on the TPS61087QDRCRQ1 selects between two fixed frequencies: grounding FREQ sets 650 kHz (higher efficiency, larger inductors), while connecting FREQ to IN sets 1.2 MHz (faster transient response, smaller 3.3-µH inductors, lower output ripple). Frequency choice directly impacts component size, thermal performance, and light-load behavior - but does not alter regulation accuracy or protection thresholds.
Can the TPS61087QDRCRQ1 be used in functional safety–compliant systems?
Yes, the TPS61087QDRCRQ1 is functional safety-capable with documentation available to support ISO 26262 system-level development. It includes diagnostic features such as thermal shutdown (150°C), undervoltage lockout (2.5 V), and overvoltage protection (FB >1.275 V triggers shutdown), enabling integration into ASIL-B compliant power architectures when combined with appropriate system-level monitoring.
What is the purpose of the SS (soft-start) pin on the TPS61087QDRCRQ1, and how is it configured?
The SS pin on the TPS61087QDRCRQ1 controls inrush current during startup by linearly ramping the internal current limit from 0 A to 3.2 A. A capacitor (e.g., 100 nF) connected from SS to GND is charged at 10 µA, yielding ~10-ms soft-start time. Leaving SS open disables soft-start; pulling SS low forces immediate shutdown. This feature prevents input rail collapse and reduces stress on input capacitors and upstream regulators.
Does the TPS61087QDRCRQ1 require external compensation, and why is that beneficial?
Yes, the TPS61087QDRCRQ1 requires external compensation via the COMP pin using a resistor and capacitor (e.g., 100 kΩ + 820 pF). This provides full control over loop bandwidth and phase margin, allowing optimization for diverse output capacitor ESR, inductor values, and load dynamics - especially critical in automotive applications with wide temperature and load variations where fixed-compensation converters may become unstable.
