Product details
Overview
TPS62290DRVTG4 from Texas Instruments is a synchronous step-down DC/DC converter optimized for battery-powered portable applications, delivering up to 1000 mA output current from a single Li-ion cell (2.3 V–6.0 V input), with adjustable output voltage (0.6 V to VIN), 2.25-MHz fixed switching frequency, and power save mode operation. It serves as the main POL regulator in mobile phones and wireless LAN modules.
For engineers reviewing the TPS62290DRVTG4 datasheet, TPS62290DRVTG4 pinout, TPS62290DRVTG4 application, or TPS62290DRVTG4 equivalent, key selection criteria include its 15-μA quiescent current in PFM mode, 100% duty-cycle low-dropout capability, ±1.5% output accuracy in PWM mode, dynamic voltage positioning, and WSON-6 (2 mm × 2 mm) package compatibility with space-constrained handheld designs.
Technical Context
The TPS62290DRVTG4 implements a fast-response voltage-mode control architecture with input voltage feed-forward, enabling stable regulation using small ceramic capacitors. Its dual-mode operation-fixed-frequency PWM at medium/heavy loads and automatic transition to pulse-frequency modulation (PFM) at light loads-maintains high efficiency across the full 0–1000 mA load range.
It integrates high-side (240–480 mΩ) and low-side (185–380 mΩ) synchronous MOSFETs, supports dynamic voltage positioning (+1% offset in PFM mode), and features undervoltage lockout (1.85 V falling threshold), thermal shutdown (140°C), and soft-start (250 μs ramp-up). The MODE pin enables real-time selection between noise-sensitive PWM and efficiency-optimized PFM operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 6.0 V - supports full discharge curve of single-cell Li-ion batteries, including extended-voltage variants. |
| Output Current | Up to 1000 mA - sufficient for core logic rails in smartphones and portable media players. |
| Switching Frequency | 2.25 MHz (typical) - enables use of compact 2.2 μH inductors and 10 μF ceramic output capacitors. |
| Quiescent Current | 15 μA (PFM mode, no load) - extends battery life in standby and low-power listening states. |
| Output Voltage Accuracy | ±1.5% in PWM mode - ensures stable core voltage for DSPs and application processors under dynamic load. |
| Feedback Reference | 0.6 V internal reference - allows precise programmable output from 0.6 V to VIN via external resistor divider. |
| Shutdown Current | <1 μA - minimizes battery drain during system sleep or power-off states. |
Pinout & Package
TPS62290DRVTG4 is housed in a thermally enhanced 6-pin WSON (DRV) package measuring 2.0 mm × 2.0 mm × 0.8 mm, with an exposed thermal pad connected to GND for improved heat dissipation in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch node | Connects internally to both MOSFETs; requires direct routing to inductor and minimal loop area to reduce EMI and switching losses. |
| VIN | Power input | Accepts 2.3–6.0 V; must be decoupled with ≥10 μF ceramic capacitor placed adjacent to pin. |
| GND | Ground reference | Primary power return path; connects to exposed thermal pad for thermal and electrical integrity. |
| EN | Enable control | Active-high logic input; pulling low disables converter and reduces current draw to <1 μA. |
| FB | Feedback input | Senses output voltage via external resistor divider; sets regulated output per VOUT = 0.6 V × (1 + R1/R2). |
| MODE | Operating mode select | Low = auto PFM/PWM transition; high = forced fixed-frequency PWM for noise-sensitive analog sections. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to minimize undershoot/overshoot during rapid load transients (e.g., CPU burst activity). |
| 100% Duty-Cycle Operation | Enables dropout as low as IOUT × (RDS(on)_HS + RL), extending usable battery voltage down to ~1.8 V at full load. |
| Integrated Synchronous MOSFETs | Eliminates need for external rectifier; high-side RDS(on) ≤480 mΩ and low-side ≤380 mΩ reduce conduction loss and improve efficiency. |
| Soft-Start Ramp | 250 μs output voltage rise (5% to 95%) limits inrush current and prevents input rail collapse on weak sources like coin cells. |
| Thermal Shutdown Protection | Activates at TJ ≥140°C with 20°C hysteresis, preventing damage during sustained overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62291DRVT | Fixed 3.3 V output; no FB pin required; identical DRV package and pinout. | Eliminates external feedback resistors but lacks output adjustability; suited for fixed-rail systems only. | Select when 3.3 V is required and board space for resistor network is constrained. |
| TPS62293DRVT | Fixed 1.8 V output; same package and thermal characteristics; shares all control logic and protection features. | Optimized for memory or core logic rails where 1.8 V is standard; removes feedback design complexity. | Choose for 1.8 V applications needing drop-in simplicity without sacrificing efficiency or transient response. |
Compared with TPS62290DRVTG4, the TPS62291DRVT and TPS62293DRVT offer identical performance and layout compatibility but trade programmability for fixed-output convenience-making them ideal for volume production where output voltage is standardized and BOM simplification is prioritized.

FAQ
What is the maximum output current capability of the TPS62290DRVTG4?
The TPS62290DRVTG4 delivers up to 1000 mA continuous output current when VIN ≥ 2.7 V. At lower input voltages (2.5–2.7 V), max output drops to 600 mA; below 2.5 V, it is limited to 300 mA due to internal current limiting and MOSFET RDS(on) constraints. This derating ensures stable regulation across the full Li-ion battery discharge range.
How does the MODE pin affect the operation of the TPS62290DRVTG4?
The MODE pin on the TPS62290DRVTG4 selects between two operating modes: pulling MODE low enables automatic PFM/PWM transition for peak efficiency at light loads, while pulling MODE high forces fixed-frequency PWM operation-ideal for noise-sensitive analog circuits. The pin accepts standard CMOS logic levels and can be dynamically toggled during operation without reset.
Can the TPS62290DRVTG4 support adjustable output voltages, and what is the minimum programmable value?
Yes, the TPS62290DRVTG4 supports fully adjustable output via the FB pin and external resistor divider. With its 0.6 V internal reference, the minimum programmable output is 0.6 V (when R2 = 0 Ω), and the upper limit is VIN. Typical configurations include 1.2 V, 1.8 V, and 3.3 V; resistor values must keep total divider impedance ≤1 MΩ for noise immunity.
What thermal considerations apply to the TPS62290DRVTG4 in a 2-layer PCB design?
In a standard 2-layer PCB, the TPS62290DRVTG4's exposed thermal pad must be soldered to a solid GND copper pour with ≥4 thermal vias (0.3 mm diameter) connecting to inner or bottom-layer GND planes. With this layout, junction-to-board thermal resistance (RθJB) is 37.2°C/W, allowing ~1.5 W power dissipation before reaching 125°C junction temperature at 25°C ambient.
Does the TPS62290DRVTG4 include short-circuit protection, and how does it behave under fault conditions?
Yes, the TPS62290DRVTG4 integrates cycle-by-cycle current limiting on both high-side and low-side MOSFETs, with a typical forward current limit of 1.4 A. During output short-circuit, the device enters hiccup mode-shutting down for ~20 ms after current-limit activation, then attempting restart. This protects internal switches and external components while limiting average power dissipation.
