Product details
Overview
TPS62230DRYR from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter in a 1 mm × 1.5 mm USON-6 package, delivering up to 500 mA output current with fixed 2.5 V output, 2.05–6 V input range, and 94% peak efficiency. It serves as a high-efficiency replacement for LDOs in space-constrained portable audio and low-power wireless systems.
For engineers reviewing the TPS62230DRYR datasheet, TPS62230DRYR pinout, TPS62230DRYR application, or TPS62230DRYR equivalent, key selection criteria include its 3-MHz switching frequency enabling ultra-small filter components (1 μH inductor, 4.7 μF capacitor), 22-μA quiescent current in power-save mode, and forced PWM capability via MODE pin - all critical for battery-powered designs requiring low ripple and extended runtime.
Technical Context
The TPS62230DRYR implements a hysteretic PWM controller topology supporting both automatic power-save mode (PFM at light loads) and forced PWM mode (quasi-fixed frequency, no pulse skipping). Its internal 0.7-V reference feeds a precision feedback loop with ±2.5% output voltage accuracy across –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 undervoltage lockout (UVLO) with 1.9-V rising threshold. Thermal shutdown activates at 150°C with 20°C hysteresis, ensuring robust operation under overload or poor thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V - eliminates external resistor divider, reduces BOM count and layout sensitivity. |
| Switching Frequency | 3 MHz - enables use of 1-μH inductors and 4.7-μF ceramic capacitors, minimizing solution size to <12 mm². |
| Input Voltage Range | 2.05 V to 6 V - supports single Li-ion (including deep discharge), two alkaline, or Li-primary batteries without pre-regulation. |
| Max Output Current | 500 mA - sufficient for DSP cores, RF transceivers, and camera sensor rails in portable devices. |
| Quiescent Current | 22 μA in power-save mode - extends battery life in standby or low-activity states without sacrificing regulation. |
| Efficiency | Up to 94% - significantly exceeds LDO efficiency at medium-to-heavy loads, reducing thermal load and power loss. |
| PSRR | Up to 90 dB - suppresses input supply noise, making it suitable for noise-sensitive analog/RF circuitry. |
Pinout & Package
TPS62230DRYR is housed in a 6-pin USON (DRY) package measuring 1.0 mm × 1.5 mm × 0.6 mm, optimized for ultra-thin portable PCBs with ≤0.6-mm height constraint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE (Pin 1) | Mode control input | Pull low for automatic PFM/PWM transition; pull high for forced PWM mode - enables deterministic noise filtering or ultra-low ripple operation. |
| SW (Pin 2) | Power switch node | Connects to external inductor; carries high-frequency switched current - requires tight layout and Kelvin connection to minimize EMI. |
| VIN (Pin 3) | Input power supply | Accepts 2.05–6 V; must be decoupled with ≥2.2-μF ceramic capacitor close to pin to stabilize high-frequency switching. |
| GND (Pin 4) | Power ground | Primary return path for high-current switching loops - must be connected to solid ground plane with minimal impedance. |
| EN (Pin 5) | Enable input | Active-high logic; pulling low disables converter and reduces current draw to <1 μA - used for power sequencing or system sleep control. |
| FB (Pin 6) | Feedback input | Internally tied to 2.5 V output; not externally configurable - simplifies design but prohibits adjustable output variants. |
Key Features
| Feature | Design Value |
|---|---|
| 100% duty cycle operation | Enables lowest dropout performance - maintains regulation even when VIN approaches VOUT (e.g., 2.6 V → 2.5 V), critical for end-of-battery-life operation. |
| Optimized power-save mode | Delivers <10 mVpp output ripple with 1-μH/4.7-μF filter at light loads - avoids audible noise and meets RF/ADC supply requirements without forced PWM. |
| High PSRR (90 dB) | Rejects noise from noisy shared input rails (e.g., USB or PMIC outputs), eliminating need for additional LC filtering in sensitive analog sections. |
| Integrated soft-start | Ramps output in ~100 μs with monotonic behavior - prevents inrush current and input droop on weak sources like coin cells or aging batteries. |
| Thermal shutdown with hysteresis | Shuts down at 150°C and resumes at 130°C - protects against sustained overload while avoiding thermal cycling during transient overloads. |

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 3-MHz frequency, package, and feature set. | Targets lower-voltage DSP cores or I/O rails where 1.8 V is required instead of 2.5 V. | Select when system architecture mandates 1.8 V supply - same layout, same efficiency profile, only output voltage differs. |
| TPS62235DRYR | Fixed 1.2 V output; 2-MHz switching frequency; same USON-6 package and 500-mA rating. | Suitable for ultra-low-voltage logic or memory interfaces needing 1.2 V with relaxed EMI constraints. | Choose for 1.2-V rails where lower switching frequency eases EMI filtering; not drop-in due to different frequency and output voltage. |
Compared with TPS62230DRYR, TPS62231DRYR offers identical performance at 1.8 V - ideal for pin-compatible voltage scaling - while TPS62235DRYR trades 3-MHz speed for 1.2 V output and 2-MHz operation, better suited for noise-tolerant, lower-voltage domains where smaller inductors are less critical.

FAQ
What is the fixed output voltage of the TPS62230DRYR?
The TPS62230DRYR provides a factory-trimmed fixed output voltage of 2.5 V with ±2.5% accuracy over –40°C to 125°C junction temperature. This eliminates the need for external feedback resistors, reduces component count, and improves stability versus adjustable regulators - a key advantage in space-constrained portable designs where the TPS62230DRYR is commonly deployed.
Does the TPS62230DRYR support forced PWM mode, and how is it enabled?
Yes, the TPS62230DRYR supports forced PWM mode via the MODE pin (Pin 1): pulling MODE high forces continuous quasi-fixed-frequency operation, eliminating pulse skipping and enabling predictable EMI filtering. This is essential for noise-sensitive applications like RF transceivers or high-resolution ADCs where the TPS62230DRYR's 90-dB PSRR and controlled switching behavior are leveraged.
What is the minimum input voltage required for the TPS62230DRYR to start up and operate?
The TPS62230DRYR requires a minimum input voltage of 2.05 V to initiate startup and sustain operation, as defined by its undervoltage lockout (UVLO) rising threshold. This allows reliable function down to the end-of-discharge voltage of single Li-ion cells and compatibility with two-alkaline or Li-primary battery sources - a critical specification for battery longevity in devices using the TPS62230DRYR.
Can the TPS62230DRYR operate with a 100% duty cycle, and what is its practical benefit?
Yes, the TPS62230DRYR supports 100% duty cycle operation, allowing it to maintain regulation when input voltage drops to within ~50 mV of the 2.5 V output (e.g., VIN = 2.55 V). This maximizes usable battery energy in portable systems - a defining advantage over many competing buck converters and a key reason the TPS62230DRYR is selected for long-runtime consumer electronics.
What external components are required for basic operation of the TPS62230DRYR?
The TPS62230DRYR requires only three external components for full operation: a 1-μH power inductor (connected to SW pin), a 2.2-μF input ceramic capacitor (at VIN), and a 4.7-μF output ceramic capacitor (at VOUT/FB). This minimal BOM - enabled by its 3-MHz switching frequency and integrated feedback - delivers a total solution area under 12 mm², a core value proposition of the TPS62230DRYR in ultra-compact designs.
