Product details
Overview
TPS61022RWUR from Texas Instruments is a synchronous 8-A boost converter IC designed for ultra-low-input-voltage power conversion in battery- and supercapacitor-powered IoT and portable systems. It operates from 0.5 V to 5.5 V input, delivers adjustable 2.2–5.5 V output, features dual internal MOSFETs (12 mΩ LS / 18 mΩ HS), 8-A valley current limit, and achieves 94.7% efficiency at 3.6 VIN/5 VOUT/3 A - enabling USB port power delivery from deeply discharged energy sources.
For engineers reviewing the TPS61022RWUR datasheet, TPS61022RWUR pinout, TPS61022RWUR application, or TPS61022RWUR equivalent, this page delivers verified functional identity, validated 7-pin VQFN package mapping, confirmed light-load PFM/PWM mode control via MODE pin, true input-output disconnection in shutdown, and real-world supercap backup implementation constraints - all critical for low-voltage DC-DC design validation and BOM selection.
Technical Context
The TPS61022RWUR implements adaptive constant-on-time valley-current-mode control with quasi-constant 1-MHz switching above 1.5 VIN, scaling down to 0.6 MHz below 1 VIN to sustain high step-up ratio and efficiency. Its integrated dual-MOSFET power stage supports pass-through operation when VIN > VOUT, eliminating unnecessary switching losses.
Functional modes are determined by the MODE pin: logic low enables auto PFM for <26 µA quiescent current at VOUT, while logic high forces PWM for fixed-frequency operation and noise-sensitive applications. Protection includes 5.7-V output overvoltage lockout, thermal shutdown at 150°C, and short-circuit current limiting with pre-charge staging.

Pinout & Package
TPS61022RWUR is housed in a thermally enhanced 2-mm × 2-mm VQFN-7 package (RWU) with exposed thermal pad. Pin 1 is GND; pin 7 is VIN. The package supports high-power density layouts with minimal PCB area and efficient heat dissipation through the bottom thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Power ground reference | Primary return path for SW, VOUT, and internal regulators; must be connected to large copper pour adjacent to thermal pad. |
| SW | Power switch node | Drain of internal low-side NMOS and source of high-side PMOS; connects directly to inductor; requires tight layout to minimize ringing. |
| VOUT | Regulated output | Delivers boosted voltage; ceramic capacitor must be placed within 2 mm of VOUT and GND pins to suppress ripple and ensure stability. |
| FB | Feedback input | Senses output via resistor divider; 600-mV internal reference enables precise output programming with ±2.5% accuracy over temperature. |
| EN | Enable control | Active-high logic input; 1.2-V threshold allows direct connection to microcontroller GPIO; pulls device into full shutdown with <0.6-µA leakage. |
| MODE | Light-load mode select | Logic-high = forced PWM (fixed frequency); logic-low = auto PFM (ultra-low IQ); no pull-up/down required - driven directly by host. |
| VIN | Input power supply | Accepts 0.5–5.5 V; UVLO rising threshold is 1.8 V for startup, but sustains operation down to 0.5 V once regulated. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 0.5-V start-up capability | Enables power delivery from near-dead batteries or supercapacitors at end-of-discharge, extending usable energy window. |
| True input-output disconnection | Shuts off both internal MOSFETs during shutdown, eliminating reverse leakage and ensuring zero load current from source. |
| Pass-through mode | Automatically bypasses switching when VIN > VOUT, reducing conduction loss and improving efficiency in high-input scenarios. |
| Integrated OVP and short-circuit protection | 5.7-V output overvoltage lockout and dynamic current limiting prevent damage from feedback divider faults or output shorts. |
| Thermal shutdown with hysteresis | 150°C trip point with 20°C hysteresis ensures safe recovery after overload or poor heatsinking without oscillation. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61023RWUR | Same 2-mm × 2-mm VQFN-7 package; identical pinout; 10-A valley current limit; 1.2-V minimum start-up voltage. | Higher current capability suits 4-A loads; less suitable for sub-1-V supercap discharge due to higher UVLO. | Select TPS61023RWUR only if ≥4-A output and >1.2-V minimum input are guaranteed; otherwise TPS61022RWUR provides superior ultra-low-VIN headroom. |
| MAX77818EWL+ | 3.2-mm × 3.2-mm WLP-20; integrates buck-boost + fuel gauge; 6-A max output; 2.5-V min input. | System-level PMIC vs standalone boost; lacks 0.5-V capability; adds battery monitoring but increases footprint and complexity. | Choose MAX77818EWL+ only when multi-rail power management and fuel gauging are required; TPS61022RWUR remains optimal for dedicated ultra-low-VIN boost. |

FAQ
What is the minimum input voltage required for TPS61022RWUR to start switching?
The TPS61022RWUR requires a minimum 1.8-V input voltage to initiate startup (UVLO rising threshold), but once enabled and regulating, it sustains operation down to 0.5 V. This two-stage behavior allows reliable boot from partially charged sources while maximizing usable energy from supercapacitors or depleted batteries. The TPS61022RWUR achieves this via internal charge pump and adaptive control architecture.
How does the MODE pin affect efficiency and noise in TPS61022RWUR operation?
When the MODE pin is pulled low, the TPS61022RWUR enters auto PFM mode, reducing quiescent current to 26 µA at VOUT and improving light-load efficiency - but with variable switching frequency that may cause audible noise. When MODE is high, the TPS61022RWUR forces fixed-frequency PWM, eliminating frequency modulation artifacts but increasing light-load IQ to ~32 µA. Both modes are fully supported in the TPS61022RWUR datasheet with validated performance curves.
Does TPS61022RWUR support true load disconnect during shutdown?
Yes, the TPS61022RWUR provides true input-to-output disconnection during shutdown: both internal high-side and low-side MOSFETs are fully turned off, resulting in <3.5-µA total shutdown current and zero DC path between VIN and VOUT. This prevents battery drain in always-connected backup systems and meets stringent leakage requirements in medical and metering applications. The TPS61022RWUR specification confirms this behavior under ISD test conditions.
What protection features are integrated into the TPS61022RWUR?
The TPS61022RWUR integrates output overvoltage protection (5.7-V threshold), thermal shutdown (150°C trip with 20°C hysteresis), output short-circuit protection with staged current limiting, and undervoltage lockout. It also features pass-through mode to avoid unnecessary switching when VIN exceeds VOUT, reducing stress and improving reliability. All protections are hardware-based and operate independently of external control - a core safety feature of the TPS61022RWUR design.
Can TPS61022RWUR be used with ceramic output capacitors only?
Yes, the TPS61022RWUR is fully compatible with ceramic-only output capacitance - no electrolytic or tantalum capacitors are required. The datasheet specifies a minimum 30-µF effective output capacitance for ≥3-A loads, achievable with three parallel 22-µF X7R ceramics. Layout guidance mandates placement within 2 mm of VOUT and GND pins to maintain stability and minimize ripple. This ceramic-only support simplifies BOM, improves lifetime, and reduces board area - key advantages confirmed for the TPS61022RWUR.
