Product details
Overview
TPS62233DRYR from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter optimized for portable battery-powered systems, delivering up to 500 mA output current with fixed 3.0 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 TPS62233DRYR datasheet, TPS62233DRYR pinout, TPS62233DRYR application, or TPS62233DRYR equivalent, key selection criteria include its 3-MHz switching frequency, 22-μA quiescent current in power-save mode, 0.7-V internal reference, forced-PWM capability via MODE pin, and ultra-small 12-mm² solution size with ≤0.6-mm height.
Technical Context
The TPS62233DRYR implements a hysteretic PWM controller topology enabling stable 3-MHz operation without external compensation, supporting both automatic PFM/PWM transition and user-enforced PWM mode via the MODE pin. Its integrated high-side (600–850 mΩ) and low-side (350–480 mΩ) MOSFETs enable synchronous rectification and 100% duty-cycle operation for low-dropout regulation.
It features undervoltage lockout (UVLO) with 1.8–2.05 V thresholds, thermal shutdown at 150°C with 20°C hysteresis, and soft-start with ~100 μs ramp time. The FB pin connects directly to the output capacitor for precise 0.7-V reference-based regulation, and EN pin enables system-level power sequencing with <1 μA shutdown current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2.5% over –40°C to 125°C junction temperature - ensures stable core voltage for DSPs and image sensors. |
| Switching Frequency | 3 MHz nominal - enables use of tiny 2.2-μH inductors and 4.7-μF output capacitors, minimizing PCB area. |
| Max Output Current | 500 mA continuous - supports moderate-load applications like camera ISP cores and audio codecs. |
| Quiescent Current | 22 μA typical in power-save mode - extends battery life in standby or light-load states. |
| Input Voltage Range | 2.05 V to 6 V - compatible with single Li-ion (2.7–4.2 V), Li-primary, or two alkaline cells. |
| Efficiency | Up to 94% at medium load - reduces thermal stress and improves power density vs. LDO alternatives. |
| Package | 6-pin USON (DRY), 1.0 mm × 1.5 mm × 0.6 mm - supports ultra-thin, space-constrained portable designs. |
Pinout & Package
TPS62233DRYR is housed in a 6-pin ultra-thin USON (DRY) package measuring 1.0 mm × 1.5 mm × 0.6 mm, optimized for minimal board footprint and height-constrained applications such as wearables and compact cameras.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE (Pin 1) | Mode control input | Pull low for auto PFM/PWM transition; pull high to force continuous PWM mode - eliminates audible noise and enables predictable EMI filtering. |
| SW (Pin 2) | Power switch node | Connects to external inductor; carries high-frequency switched current - requires tight layout to minimize EMI and losses. |
| VIN (Pin 3) | Input power supply | Accepts 2.05–6 V; must be decoupled with ≥2.2-μF ceramic capacitor close to pin - critical for stability and UVLO margin. |
| GND (Pin 4) | Power ground | Primary return path for high-current loops; must be connected to low-impedance ground plane - essential for thermal and noise performance. |
| EN (Pin 5) | Enable input | Active-high logic; floating not allowed - enables power sequencing and system-level shutdown with <1 μA quiescent draw. |
| FB (Pin 6) | Feedback input | Direct connection to output capacitor; senses 0.7-V internal reference - no external resistor divider needed for fixed-output variants. |
Key Features
| Feature | Design Value |
|---|---|
| 3-MHz fixed-frequency operation | Enables consistent EMI profile and use of miniature passive components - reduces total solution size to <12 mm². |
| Power-save mode with 22-μA IQ | Maintains >85% efficiency down to 100 μA load - extends runtime in always-on sensor or standby subsystems. |
| Forced PWM mode via MODE pin | Eliminates pulse skipping and associated low-frequency ripple - required for noise-sensitive RF and audio signal chains. |
| 100% duty cycle capability | Supports dropout as low as VIN – VOUT ≈ 0 V - preserves regulation during brownout or battery depletion. |
| Integrated MOSFETs with 600/350-mΩ RDS(ON) | Reduces external component count and conduction losses - simplifies design and improves thermal performance. |

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 or FPGA I/O rails instead of 3.0-V core supplies. | Select when system requires 1.8 V rather than 3.0 V - same layout, no redesign needed. |
| TPS62237DRYR | Fixed 3.3 V output; 2-MHz switching frequency; same USON package and control architecture. | Suitable for 3.3-V MCU or interface ICs where slightly higher output and relaxed EMI filtering are acceptable. | Choose for 3.3-V applications needing lower switching frequency - may ease EMI compliance but increases inductor size. |
Compared with TPS62233DRYR, TPS62231DRYR provides identical performance at 1.8 V for lower-power logic, while TPS62237DRYR offers 3.3 V at 2 MHz for less aggressive size constraints - both share pinout, thermal behavior, and control interface, enabling rapid voltage-scaling adaptations.

FAQ
What is the output voltage of the TPS62233DRYR?
The TPS62233DRYR provides a fixed 3.0 V output voltage with ±2.5% accuracy across –40°C to 125°C junction temperature. This is achieved using an internal 0.7-V reference and factory-trimmed feedback network - no external resistors are required. The output remains stable under load transients and line variations within its 2.05–6 V input range.
Does the TPS62233DRYR support forced PWM mode?
Yes, the TPS62233DRYR supports forced PWM mode via the MODE pin: pulling MODE high disables power-save mode and maintains continuous quasi-fixed-frequency switching. This eliminates low-frequency ripple and audible noise, making TPS62233DRYR suitable for RF, audio, and precision analog applications where spectral purity is critical.
What is the minimum input voltage required for the TPS62233DRYR to operate?
The TPS62233DRYR requires a minimum input voltage of 2.05 V to start and maintain regulation. Its undervoltage lockout (UVLO) has a falling threshold of 1.8–1.9 V and rising threshold of 1.9–2.05 V, allowing operation down to near-dead battery levels - ideal for single-cell Li-primary or dual-alkaline systems.
Can the TPS62233DRYR be used in space-constrained wearable designs?
Yes, the TPS62233DRYR is explicitly optimized for ultra-compact layouts: its 1 mm × 1.5 mm × 0.6 mm USON package and 12-mm² total solution size (including 2.2-μH inductor and 4.7-μF capacitor) meet stringent height and area requirements in wearables, hearables, and compact IoT sensors.
What is the shutdown current of the TPS62233DRYR?
The TPS62233DRYR draws less than 1 μA in shutdown mode when the EN pin is pulled low. During shutdown, both high-side and low-side MOSFETs are disabled, the internal feedback divider is disconnected, and all control circuitry is powered down - minimizing battery drain in off-state or deep-sleep configurations.
