Product details
Overview
TPS61022RWUT from Texas Instruments is a synchronous 8-A boost converter IC designed for ultra-low-input-voltage power supply applications in portable and IoT devices. It operates from 0.5 V to 5.5 V input, delivers adjustable output from 2.2 V to 5.5 V, features dual internal MOSFETs (12 mΩ LS / 18 mΩ HS), supports 1-MHz/0.6-MHz adaptive switching, and enables USB port and supercapacitor backup power systems.
For engineers reviewing the TPS61022RWUT datasheet, TPS61022RWUT pinout, TPS61022RWUT application, or TPS61022RWUT equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative options, and supply-chain support details specific to the RWU-package variant.
Technical Context
The TPS61022RWUT implements valley-current-mode control with adaptive constant on-time PWM architecture, enabling stable regulation across wide VIN–VOUT ratios. Its dual-MOSFET synchronous rectification eliminates external diode losses, while the MODE pin selects between forced PWM (fixed frequency, low noise) and auto PFM (high light-load efficiency).
It integrates undervoltage lockout (1.8-V startup threshold), true input-output disconnection during shutdown, 5.7-V output overvoltage protection, thermal shutdown at 150°C, and pass-through mode when VIN exceeds VOUT - all within a thermally enhanced 2-mm × 2-mm VQFN-7 package with exposed thermal pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.5 V to 5.5 V - supports deeply discharged supercapacitors and single-cell alkaline/NiMH batteries. |
| Output Voltage Range | 2.2 V to 5.5 V - adjustable via external resistor divider; enables USB 5-V compliance and flexible system rail generation. |
| Switch Current Limit | 8-A valley limit - ensures robust 3-A continuous output at 5 V from 3.6-V input with margin for transient loads. |
| Efficiency | 94.7% at VIN = 3.6 V, VOUT = 5 V, IOUT = 3 A - minimizes thermal rise and extends battery runtime in compact layouts. |
| Switching Frequency | 1 MHz (VIN > 1.5 V) / 0.6 MHz (VIN < 1 V) - balances EMI control and conversion efficiency across input range. |
| Quiescent Current | 26 µA into VOUT in light load - sustains ultra-low-power operation in always-on IoT sensor nodes. |
| Reference Accuracy | ±2.5% over –40°C to +125°C - guarantees stable output regulation in automotive and industrial ambient conditions. |
Pinout & Package
TPS61022RWUT uses a 2-mm × 2-mm VQFN-7 package with wettable flank leads and an exposed thermal pad (pin 0). The package supports high-density PCB layout and efficient heat dissipation through bottom-side thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Primary return path for SW, VOUT, and internal logic; must be connected to low-impedance ground plane adjacent to thermal pad. |
| SW (Pin 2) | Switch node | Drain of internal low-side NMOS and source of high-side PMOS; connects directly to inductor; requires minimal loop area for EMI control. |
| VOUT (Pin 3) | Regulated output | Delivers boosted voltage; output capacitor must be placed adjacent to VOUT and GND pins to minimize AC impedance. |
| FB (Pin 4) | Voltage feedback input | Senses output via resistor divider; internal 600-mV reference sets VOUT = 600 mV × (1 + R1/R2); leakage current ≤20 nA preserves accuracy. |
| EN (Pin 5) | Enable control input | Active-high logic interface; 1.2-V threshold enables device; 0.4-V threshold disables it into full shutdown with <0.6-µA VIN current. |
| MODE (Pin 6) | Light-load mode select | Logic-high forces PWM; logic-low enables auto PFM; determines trade-off between efficiency (PFM) and EMI/noise (PWM). |
| VIN (Pin 7) | Input power supply | Accepts 0.5–5.5 V; includes UVLO (1.8-V rising threshold); supplies internal bias and gate drivers; requires local 10-µF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 0.5-V start-up capability | Enables power delivery from near-dead supercapacitors or single-cell primary batteries without external pre-bias. |
| True input-output disconnection | Shuts down both internal FETs during EN=low, eliminating reverse current and ensuring zero standby drain in battery-critical systems. |
| Adaptive switching frequency | Reduces from 1 MHz to 0.6 MHz as VIN drops below 1.5 V - improves efficiency at high step-up ratios without sacrificing regulation. |
| Integrated 5.7-V overvoltage protection | Prevents damage from feedback resistor misplacement or open FB trace; latches off until VOUT falls 0.1 V below threshold. |
| Pass-through mode | Activates when VIN > VOUT; bypasses switching to reduce conduction loss - critical for hybrid battery/supercap systems with overlapping voltage ranges. |
Applications
| USB Port Power Delivery | Supercapacitor Backup Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Higher 10-A current limit; 2.7–12-V input; no sub-1-V operation; 3-mm × 3-mm QFN-16 package. | Targets higher-power applications (e.g., 5-V/5-A USB PD); unsuitable for supercap backup due to 2.7-V min VIN. | Choose TPS61088RHLR only if ≥10-A output and >2.7-V input are required; not a drop-in replacement for TPS61022RWUT. |
| MAX17222ETA+ | 0.4-V min input; 500-mA output; 1.9-mm × 1.9-mm WLP-6; no MODE pin or pass-through mode. | Designed for micro-power wearables; lacks current capability and protection features needed for USB/GPRS use cases. | Choose MAX17222ETA+ only for sub-100-mA, ultra-small-footprint applications where TPS61022RWUT's performance is over-specified. |
Compared with TPS61022RWUT, TPS61088RHLR offers higher current but sacrifices ultra-low-voltage operation, while MAX17222ETA+ achieves smaller size and lower VIN at the cost of output capability and system-level protections - making TPS61022RWUT uniquely balanced for 0.5–5.5-V, 3–5-V, 3-A portable power.

FAQ
What is the minimum input voltage required for TPS61022RWUT to start up and regulate?
The TPS61022RWUT requires a minimum 1.8-V input voltage to initiate startup when the output is unpowered. Once regulation is established and VOUT exceeds 2.2 V, it continues operating down to 0.5 V - enabling deep discharge utilization of supercapacitors and primary batteries. This dual-threshold behavior is confirmed in Section 6.3 and 7.3.1 of the official datasheet.
Does TPS61022RWUT support automatic transition between PWM and PFM modes?
Yes - the TPS61022RWUT supports auto PFM operation when the MODE pin is pulled low. In this mode, it dynamically switches between pulse-frequency modulation at light loads and quasi-constant-frequency PWM under moderate-to-heavy loads, achieving up to 94.7% efficiency at 3 A while maintaining 26 µA quiescent current. This behavior is detailed in Sections 1, 7.4.2, and Figure 7-1.
Can TPS61022RWUT safely disconnect the load from the input during shutdown?
Yes - the TPS61022RWUT provides true input-output disconnection during shutdown. When the EN pin is driven low, both internal MOSFETs turn off completely, blocking reverse current and reducing shutdown current to ≤0.6 µA. This feature is explicitly documented in Section 1 (Features), Section 7.3.2, and Absolute Maximum Ratings Table 6.1.
What protection features are integrated into TPS61022RWUT?
The TPS61022RWUT integrates output overvoltage protection (5.7-V threshold), thermal shutdown (150°C trip point), output short-circuit protection (700-mA current limit at VOUT < 0.4 V), and undervoltage lockout (1.8-V rising threshold). All protections are hardware-based and do not require external components, as verified in Sections 1, 6.5, and 7.3.6–7.3.8.
Is the TPS61022RWUT package compatible with automated optical inspection (AOI) and reflow soldering?
Yes - the TPS61022RWUT's RWU package is a 2-mm × 2-mm VQFN-7 with wettable flank leads, fully compliant with IPC-7351B footprint standards and qualified for standard lead-free reflow profiles (J-STD-020). Its exposed thermal pad and defined solder mask openings support reliable AOI detection and void-free solder joint formation, as specified in TI's packaging documentation SLVSDX7D.
