Product details
Overview
TPS613783QWRTERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous boost converter with integrated load disconnect, 25-µA quiescent current, programmable 4.0–18.5 V output, 1–4.8 A peak current limit, and 200 kHz–2.2 MHz switching frequency. It delivers regulated power to ADAS camera modules, infotainment displays, and eCall backup supplies where low-noise, high-efficiency, and input-output isolation are critical.
For engineers reviewing the TPS613783QWRTERQ1 datasheet, TPS613783QWRTERQ1 pinout, TPS613783QWRTERQ1 application, or TPS613783QWRTERQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade protection features, and real-world implementation constraints including spread-spectrum EMI control, wettable-flank QFN packaging, and true load disconnect during shutdown.
Technical Context
The TPS613783QWRTERQ1 uses peak current mode control with fixed-frequency PWM operation under medium-to-heavy loads and supports dual light-load modes-auto PFM for efficiency optimization and forced PWM for noise immunity-selected via the MODE/SYNC pin. Its internal oscillator enables programmable switching frequency (200 kHz–2.2 MHz) with optional external clock synchronization and spread-spectrum modulation active only in FPWM mode.
This device integrates three N-MOSFETs: low-side (50 mΩ), high-side (50 mΩ), and isolation FET (100 mΩ), enabling true input-output disconnect during shutdown. Protection includes hiccup-mode short-circuit response, 19.3–20.5 V output overvoltage threshold, thermal shutdown at 165°C, and VIN UVLO with 160 mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 14 V - supports wide automotive battery transients including cold-crank (≥2.3 V) and load-dump (≤14 V) |
| Output Voltage Range | 4.0 V to 18.5 V - adjustable via FB resistor divider; fixed options: 5 V / 5.25 V / 5.5 V |
| Quiescent Current | 25 µA into VIN - enables always-on systems (e.g., eCall backup) with minimal battery drain |
| Peak Switch Current Limit | 1 A to 4.8 A - set by ILIM pin resistor; supports scalable output power up to ~9 W at 9 V |
| Switching Frequency | 200 kHz to 2.2 MHz - programmable via FREQ pin resistor; avoids AM band (530–1710 kHz) and enables compact L-C design |
| Load Disconnect | True isolation between VIN and VO/OUT during shutdown - eliminates standby leakage and enables safe hot-swap |
| Package | 3 mm × 3 mm WQFN-16 with wettable flank - supports automated optical inspection (AOI) and AEC-Q200-compliant reflow |
Pinout & Package
TPS613783QWRTERQ1 is housed in a 3 mm × 3 mm, 16-pin Wettable Flank Quad Flat No-lead (WQFN-RTE) package with exposed thermal pad connected to GND for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Main input supply connection (2.3–14 V); feeds internal LDO and power switches |
| BST | Bootstrap supply | Connects to SW via 0.1 µF ceramic capacitor to drive high-side MOSFET gate |
| SW | Switching node | Drain of LS FET / source of HS FET; connects to external inductor and BST capacitor |
| MODE/SYNC | Mode control & sync input | Logic high = forced PWM; logic low/floating = auto PFM; external clock input for synchronization |
| VCC | Internal LDO output | 4.8 V regulated supply (≥1 µF ceramic to GND); powers bias circuitry and gate drivers |
| GND | Power ground | Common return for LS FET source, thermal pad, and analog ground reference |
| VO | Isolation FET output | Load-connected output terminal; enables true input-output disconnect when disabled |
| OUT | HS FET drain output | Direct HS switch output; shorting to VO disables load disconnect and short-protection features |
| PG | Power good indicator | Open-drain output asserting high when VOUT is within ±5% of target (90% VREF threshold) |
| ILIM | Current limit setting | Resistor-to-GND sets peak switch current (1–4.8 A); not floating or tied to VCC |
| FB | Feedback input | Resistor divider from VO sets output voltage; reference = 0.788–0.812 V (±1.5% over temp) |
| COMP | Error amplifier output | Connect external RC network to optimize loop stability across VOUT/VIN ratios |
| EN | Enable input | Active-high logic (VIH ≥ 1.2 V); 0.4 ms delay to enable; internal 800 kΩ pull-down |
| FREQ | Frequency setting | Resistor-to-GND sets switching frequency (200 kHz–2.2 MHz); equation: FSW = 41.9/(RFREQ + 1.05) |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum EMI reduction | ±10% frequency dithering in FPWM mode only - reduces peak radiated emissions without compromising regulation |
| True load disconnect | Isolates VIN from VO/OUT during shutdown or fault - eliminates standby current path and enables safe system sequencing |
| Automotive-grade protection suite | Hiccup-mode short-circuit, 19.3–20.5 V OVP, thermal shutdown at 165°C, and 2.04 V VIN UVLO with 160 mV hysteresis |
| Flexible light-load operation | Selectable auto PFM (efficiency-optimized) or forced PWM (noise-immune) via MODE/SYNC pin - no external components required |
| Integrated power switches | LS/HS/ISO FETs with RDS(on) = 50/50/100 mΩ - eliminates external MOSFETs and gate drivers for space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS613781QWRTERQ1 | Same package and architecture but enables spread spectrum by default; fixed outputs: 5.7 V / 6.2 V / 7 V / 8 V | Preferred for higher-voltage display bias rails where EMI suppression is mandatory and 5.5 V ceiling is insufficient | Select when fixed 5.7–8 V outputs and guaranteed spread-spectrum operation are required; not drop-in for 5.5 V designs |
| TPS613785QWRTERQ1 | Same package and architecture but disables spread spectrum; fixed outputs: 9 V / 10 V / 11 V / 12 V | Targeted at high-voltage LED strings and industrial sensors needing deterministic switching frequency without dithering | Choose for 9–12 V applications where predictable EMI profile and absence of frequency modulation are design priorities |
Compared with TPS613783QWRTERQ1, TPS613781QWRTERQ1 offers higher fixed outputs and mandatory spread spectrum, while TPS613785QWRTERQ1 provides 9–12 V options without dithering-making all three variants mutually exclusive based on output voltage and EMI strategy requirements.

FAQ
What is the key functional difference between TPS613783QWRTERQ1 and other TPS61378-Q1 variants?
The TPS613783QWRTERQ1 is distinguished by its fixed 5 V / 5.25 V / 5.5 V output options and disabled spread-spectrum modulation - unlike TPS613781QWRTERQ1 (spread-spectrum enabled, 5.7–8 V outputs) or TPS613785QWRTERQ1 (no spread-spectrum, 9–12 V outputs). This makes TPS613783QWRTERQ1 optimal for 5 V sensor and interface rails where deterministic frequency behavior is preferred over EMI dithering.
Does TPS613783QWRTERQ1 support true input-output isolation during shutdown?
Yes, TPS613783QWRTERQ1 implements true load disconnect using an integrated isolation FET between VIN and VO. When EN is low or during fault conditions, the VO pin is fully disconnected from VIN, reducing shutdown current to 0.5 µA and eliminating reverse leakage - a critical feature for battery-backed eCall and always-on ADAS modules.
How is the switching frequency programmed on TPS613783QWRTERQ1?
The switching frequency of TPS613783QWRTERQ1 is set by connecting a resistor from the FREQ pin to GND. Using the formula FSW (MHz) = 41.9 / (RFREQ (kΩ) + 1.05), a 18 kΩ resistor yields 2.2 MHz, while 218 kΩ gives ~200 kHz. The FREQ pin must never be left floating or tied to VCC, and external clock synchronization overrides resistor programming when applied to MODE/SYNC.
What protection features are integrated into TPS613783QWRTERQ1?
TPS613783QWRTERQ1 integrates input undervoltage lockout (2.04 V threshold, 160 mV hysteresis), output overvoltage protection (19.3–20.5 V trip), hiccup-mode short-circuit response, thermal shutdown at 165°C (with 20°C hysteresis), and power-good indication. All protections are qualified per AEC-Q100 Grade 1 and operate across –40°C to 125°C ambient.
Can TPS613783QWRTERQ1 operate with input voltage close to or below the output voltage?
Yes, TPS613783QWRTERQ1 supports VIN close to VOUT operation and enters down-mode when VIN approaches VOUT. In such cases, peak current limit is reduced (e.g., to 2/3 ILIM or lower depending on ΔV = VIN − VOUT) and switching frequency clamped to ≤1.1 MHz if FREQ pin setting exceeds that value - ensuring stable regulation and preventing instability near the boost-to-buck transition boundary.
