Product details
Overview
TPS622314DRYR from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter optimized for battery-powered portable applications, delivering up to 500 mA output current with fixed 1.5 V output, 2.05–6 V input range, and 94% peak efficiency in a 1 mm × 1.5 mm USON package - used in low-power DSP core supplies and digital camera power rails.
For engineers reviewing the TPS622314DRYR datasheet, TPS622314DRYR pinout, TPS622314DRYR application, or TPS622314DRYR equivalent, key selection considerations include its 1.5 V fixed output, forced-PWM/Power-Save mode flexibility, 22 µA quiescent current in light-load operation, and compatibility with 2.2 µH inductors and 4.7 µF output capacitors for ultra-compact layouts under 12 mm².
Technical Context
The TPS622314DRYR implements a hysteretic PWM controller topology enabling 3 MHz switching with excellent AC load regulation and low output ripple across full load range. Its internal 0.7 V reference feeds a precision feedback loop tied to the FB pin, supporting ±2.5% output voltage accuracy over –40°C to 125°C junction temperature.
It integrates high-side (600–850 mΩ) and low-side (350–480 mΩ) MOSFETs with 850 mA typical current limit, minimum ON-time of 135 ns, and thermal shutdown at 150°C. MODE pin control enables seamless transition between PFM (for efficiency) and forced PWM (for noise-sensitive RF/audio use).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V - eliminates external resistor divider; ensures stable core supply for low-voltage DSPs and sensors. |
| Input Voltage Range | 2.05 V to 6 V - supports single Li-ion (2.7–4.2 V), Li-primary, or dual alkaline cells without dropout issues. |
| Switching Frequency | 3 MHz - enables use of tiny 2.2 µH inductors and compact 4.7 µF ceramic output capacitors; reduces solution size to <12 mm². |
| Max Output Current | 500 mA - sufficient for powering ARM Cortex-M cores, image sensors, or Bluetooth SoCs in portable devices. |
| Quiescent Current | 22 µA in Power-Save Mode - extends battery life in standby or low-activity states without compromising startup speed. |
| Efficiency | Up to 94% - minimizes thermal dissipation in space-constrained handheld enclosures; reduces need for heatsinking. |
| Operating Temp | –40°C to 125°C junction - qualified for industrial and automotive cabin-temperature environments. |
Pinout & Package
TPS622314DRYR is housed in a 6-pin 1.0 mm × 1.5 mm × 0.6 mm USON (DRY) package with wettable flanks for automated optical inspection. The package supports 0.6 mm maximum solution height and is optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE | Mode Control Input | Pull low for automatic PFM/PWM transition; pull high for forced PWM operation - critical for EMI-sensitive audio/RF subsystems. |
| SW | Switch Node | Connects to external inductor; carries high-frequency pulsed current - requires tight layout and short trace to minimize ringing. |
| VIN | Input Power Supply | Accepts 2.05–6 V; must be decoupled with ≥2.2 µF ceramic capacitor close to pin to suppress input ripple and support transient response. |
| FB | Feedback Input | Internally connected to 1.5 V output via fixed resistor divider; no external components needed - simplifies design and improves stability. |
| EN | Enable Input | Active-high logic; pulling low disables converter and reduces current draw to <1 µA - enables precise power sequencing in multi-rail systems. |
| GND | Power Ground | Common return path for VIN, SW, EN, MODE, and FB; must be solidly connected to thermal pad for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small solution size | ≤12 mm² PCB area with 2.2 µH inductor and 4.7 µF output capacitor - ideal for wearables and compact IoT edge nodes. |
| High PSRR (up to 90 dB) | Rejects input supply noise effectively - allows direct connection to noisy battery packs or shared PMIC rails without additional LDO filtering. |
| 100% duty cycle capability | Enables lowest possible dropout - maintains regulation even when VIN drops to within ~100 mV of VOUT (e.g., 1.6 V input for 1.5 V output). |
| Optimized Power-Save Mode | Delivers <10 mVpp output ripple at light loads using small external components - avoids audible coil whine in portable media players. |
| Thermal shutdown with hysteresis | Triggers at 150°C and resets at 130°C - protects against sustained overload while preventing thermal cycling during intermittent high-load bursts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYR | Fixed 1.8 V output; identical package, pinout, and feature set. | Suitable where higher core voltage is required (e.g., legacy 1.8 V I/O domains), but not drop-in for 1.5 V logic. | Select only if system architecture mandates 1.8 V - otherwise TPS622314DRYR provides better margin for 1.5 V logic families. |
| TPS62235DRYR | Fixed 1.2 V output; same 3 MHz frequency, USON-6 package, and functional modes. | Targets ultra-low-power MCU cores (e.g., MSP430FRxx) requiring 1.2 V, not compatible with 1.5 V interface standards. | Choose when powering 1.2 V domains; verify VOUT tolerance and load transient behavior match target SoC requirements. |
Compared with TPS62231DRYR (1.8 V) and TPS62235DRYR (1.2 V), the TPS622314DRYR's 1.5 V output bridges mid-range logic voltage needs - offering tighter compatibility with newer mixed-signal SoCs, improved noise margin over 1.2 V, and lower power than 1.8 V alternatives without requiring external feedback resistors.

FAQ
What is the fixed output voltage of the TPS622314DRYR?
The TPS622314DRYR delivers a fixed 1.5 V output voltage, achieved via an internal resistor divider network connected to the FB pin - eliminating the need for external feedback components and ensuring ±2.5% accuracy over –40°C to 125°C junction temperature. This makes the TPS622314DRYR ideal for powering 1.5 V logic domains in portable SoCs and sensors without calibration overhead.
Does the TPS622314DRYR support forced PWM mode?
Yes, the TPS622314DRYR supports forced PWM mode via the MODE pin: pulling MODE high disables Power-Save Mode and locks the device into quasi-fixed-frequency 3 MHz operation. This reduces output voltage ripple and simplifies EMI filtering - especially valuable in RF, audio, or clock-sensitive applications where pulse-frequency modulation noise must be avoided. The TPS622314DRYR retains full functionality in both modes without external configuration.
What is the minimum input voltage required for the TPS622314DRYR to start up?
TPS622314DRYR requires a minimum input voltage of 2.05 V to initiate startup, per its undervoltage lockout (UVLO) specification. The rising UVLO threshold is typically 1.9–2.05 V, allowing reliable operation down to near-dead battery conditions in single-cell Li-primary or dual-alkaline systems. Below this threshold, the device remains in shutdown with <1 µA current draw until VIN rises above the UVLO release point.
Can the TPS622314DRYR operate with a 2.2 µH inductor and 4.7 µF output capacitor?
Yes, the TPS622314DRYR is explicitly optimized for use with a 2.2 µH inductor and 4.7 µF ceramic output capacitor - enabling total solution size under 12 mm² and maximum height under 0.6 mm. These values are validated in TI's reference designs and electrical characteristics tables; using them ensures stable operation, ≤10 mVpp ripple in Power-Save Mode, and full 500 mA output capability across temperature.
Is the TPS622314DRYR pin-compatible with other devices in the TPS6223x family?
Yes, all TPS6223x devices including TPS622314DRYR share identical 6-pin USON (DRY) package dimensions, pinout, and footprint - enabling drop-in replacement across output voltage variants (e.g., 1.2 V, 1.5 V, 1.8 V). However, functional differences exist: EN/MODE pin termination requirements vary slightly (e.g., TPS622319 has internal pull-down), so review datasheet-specific guidance before substitution.
