Product details
Overview
TPS622314TDRYRQ1 from Texas Instruments is an AEC-Q100 qualified 3-MHz synchronous step-down DC-DC converter delivering fixed 1.5 V output at up to 500 mA, operating from 2.05 V to 6 V input, housed in a 1 × 1.5 × 0.6 mm³ 6-pin SON (DRY) package with 12 mm² minimum solution size.
For engineers reviewing the TPS622314TDRYRQ1 datasheet, TPS622314TDRYRQ1 pinout, TPS622314TDRYRQ1 application, or TPS622314TDRYRQ1 equivalent, key selection considerations include automotive-grade reliability, forced-PWM/Power-Save mode control via MODE pin, 22 μA quiescent current in PFM, 94% peak efficiency, and compatibility with 1 μH or 2.2 μH inductors and 4.7 μF output capacitor.
Technical Context
The TPS622314TDRYRQ1 implements a hysteretic PWM controller topology enabling >3 MHz switching frequency, excellent AC load regulation, and stable operation with minimal external components. It integrates high-side and low-side MOSFETs with RDS(ON) of 600–850 mΩ (PMOS) and 350–480 mΩ (NMOS) at 105°C.
Functional modes include Power Save Mode (MODE = GND) for ultra-low IQ (22 μA), forced PWM Mode (MODE = VIN) for fixed-frequency noise control, 100% duty-cycle low-dropout operation near VIN ≈ VOUT, and thermal shutdown at 150°C with 20°C hysteresis. Soft-start time is 100 μs typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V - eliminates need for external feedback resistors; supports precision rail for automotive sensors or logic. |
| Input Voltage Range | 2.05 V to 6 V - enables direct Li-ion battery (2.7–4.2 V) or pre-regulated 3.3/5 V rail operation without intermediate stage. |
| Switching Frequency | 3 MHz nominal - allows use of tiny 1 μH or 2.2 μH inductors and reduces EMI filter size; supports >3.8 MHz under specific conditions. |
| Max Output Current | 500 mA - sufficient for powering camera image signal processors (ISPs), radar MMIC bias, or MCU cores in ADAS modules. |
| Quiescent Current | 22 μA in Power Save Mode - extends battery life in always-on automotive telematics or eCall standby states. |
| Efficiency | Up to 94% - significantly exceeds linear regulators, reducing thermal load in confined 12 mm² PCB footprints. |
| Package | 6-pin SON (DRY), 1 × 1.5 × 0.6 mm³ - ultra-small footprint compatible with automated SMT assembly and space-constrained automotive modules. |
Pinout & Package
TPS622314TDRYRQ1 uses a 6-pin 1 × 1.5 mm² SON (DRY) package with wettable flanks, optimized for thermal performance (RθJA = 294.5°C/W) and reflow-solderability in automotive production.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MODE | Digital control input | High = forced PWM mode (fixed frequency, no pulse skipping); Low = automatic Power Save Mode (PFM/PWM transition); must be terminated. |
| 2 - SW | Switch node | Connects to inductor; carries high-frequency pulsed current; requires tight layout to minimize EMI and voltage spikes. |
| 3 - VIN | Main power input | Accepts 2.05–6 V; requires local 2.2 μF ceramic input capacitor placed adjacent to pin for stability and transient response. |
| 4 - GND | Power ground | Common return path for VIN, SW, FB, EN, MODE; must connect to solid thermal pad on PCB for heat dissipation. |
| 5 - EN | Enable control input | High = active operation; Low = shutdown (<1 μA IQ); supports power sequencing with other rails in multi-rail systems. |
| 6 - FB | Feedback input | Internally connected to 0.70 V reference; connects directly to output capacitor for regulation; no external resistor divider needed (fixed 1.5 V). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Rated for –40°C to +125°C junction temperature - certified for front/rear camera, surround-view, and blind-spot monitoring systems. |

FAQ
What is the output voltage of the TPS622314TDRYRQ1?
The TPS622314TDRYRQ1 provides a fixed 1.5 V output voltage. This value is factory-trimmed and does not require external feedback resistors. The device achieves ±2.5% output voltage accuracy over –40°C to +105°C ambient temperature, with internal 0.70 V reference connected to the FB pin. The TPS622314TDRYRQ1 is part of the TPS6223x-Q1 family, where the "14" suffix explicitly denotes the 1.5 V variant.
Does the TPS622314TDRYRQ1 support forced PWM mode?
Yes, the TPS622314TDRYRQ1 supports forced PWM mode via the MODE pin. When MODE is pulled high (≥0.8 V), the device operates continuously in PWM mode across all load conditions, eliminating pulse-frequency modulation (PFM) and ensuring a quasi-fixed switching frequency. This mode is essential for noise-sensitive applications like radar receivers or audio subsystems where predictable EMI spectra are required. The TPS622314TDRYRQ1 retains its 3 MHz nominal frequency in this mode but allows slight variation with input/output voltage and load.
What is the minimum input voltage required for the TPS622314TDRYRQ1 to start up?
The TPS622314TDRYRQ1 requires a minimum input voltage of 2.05 V to initiate startup. This threshold is defined by the undervoltage lockout (UVLO) circuit, which has a falling threshold of 1.8 V (typical) and rising threshold of 1.9–2.05 V. Below 2.05 V, the device remains in UVLO and will not enable switching, even if EN is high. Once VIN rises above the rising UVLO threshold, the internal soft-start begins, reaching regulated 1.5 V output in approximately 100 μs. The TPS622314TDRYRQ1 remains functional down to the falling UVLO level during operation.
Can the TPS622314TDRYRQ1 operate with a 1 µH inductor?
Yes, the TPS622314TDRYRQ1 is fully characterized and optimized for use with a 1 µH inductor, as confirmed in the datasheet's Recommended Operating Conditions and Typical Application sections. The device's internal compensation is tuned for stable operation with 1 µH (or 2.2 µH) inductance paired with a 4.7 µF output capacitor. Using a 1 µH inductor yields higher ripple current but enables the smallest possible solution size and faster transient response-ideal for ADAS camera modules where board area is constrained and dynamic load steps occur frequently.
Is the TPS622314TDRYRQ1 pin-compatible with other devices in the TPS6223x-Q1 family?
Yes, the TPS622314TDRYRQ1 is pin-compatible with other members of the TPS6223x-Q1 family, including TPS62231TDRYRQ1 (1.8 V) and TPS62232TDRYRQ1 (1.2 V). All share the identical 6-pin DRY (SON) package, identical pin configuration (MODE, SW, VIN, GND, EN, FB), and identical recommended external component values. This allows designers to reuse PCB layouts across multiple output voltage variants, simplifying BOM management and enabling rapid voltage rail optimization during system validation without hardware changes.
