Product details
Overview
TLV62084ADSGT from Texas Instruments is a 2-A synchronous step-down DC/DC converter in a 2-mm × 2-mm WSON-8 package with thermal pad, operating from 2.7 V to 6 V input and delivering regulated output voltages from 0.5 V to 4 V via external feedback divider. It features DCS-Control™ architecture, 2-MHz nominal switching frequency, power good (PG) open-drain output with low-level assertion, and integrated high- and low-side MOSFETs with 120 mΩ / 90 mΩ RDS(on). It is used in battery-powered portable devices and point-of-load regulation where high light-load efficiency and fast transient response are required.
For engineers reviewing the TLV62084ADSGT datasheet, TLV62084ADSGT pinout, TLV62084ADSGT application, or TLV62084ADSGT equivalent, key selection criteria include its 2-A continuous output current capability, 2.7–6-V input range, PG logic behavior (low during fault, high-impedance when enabled and in regulation), DCS-Control™ seamless PWM-to-PFM transition, and WSON-8 thermal-pad package for compact, thermally robust designs.
Technical Context
The TLV62084ADSGT implements DCS-Control™ topology-combining voltage-mode stability with hysteretic-like transient response-enabling single-loop control across PWM and power save modes without external compensation. Its internal error amplifier regulates FB against a precise 0.45-V reference, while VOS provides dedicated output voltage sensing for improved load regulation accuracy.
It operates in forced PWM mode at medium-to-heavy loads (≥200 mA typical), then transitions seamlessly into discontinuous-conduction PFM mode below that threshold, reducing quiescent current to 30 µA and maintaining >85% efficiency down to 100 µA output current. The 100% duty-cycle mode enables ultra-low dropout operation, critical for Li-ion battery discharge curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A continuous - supports high-current rails like core logic or memory supplies without external current boosting. |
| Input Voltage Range | 2.7 V to 6 V - compatible with single-cell Li-ion (2.7–4.2 V), USB-powered systems (4.5–5.5 V), and wide-input industrial rails. |
| Feedback Reference | 0.45 V ±2.7% - enables precise output programming down to 0.5 V using standard resistor dividers; low reference reduces divider current loss. |
| Switching Frequency | 2 MHz nominal - allows use of small 1-µH inductors and 10–22-µF ceramic output capacitors for space-constrained layouts. |
| Quiescent Current | 30 µA - ensures >90% efficiency at 100 µA load, extending battery life in always-on sensor or standby circuits. |
| Power Good Logic | Active-low open-drain (TLV62084A variant) - asserts low when VOUT drops ≤90% of nominal; requires external pull-up; enables rail sequencing and system monitoring. |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design; auto-recovery on cooldown. |
Pinout & Package
TLV62084ADSGT is housed in an 8-terminal WSON package (DSG) measuring 2.0 mm × 2.0 mm with exposed thermal pad soldered to PCB ground for enhanced thermal dissipation (θJA = 59.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | Active-high logic control; must be pulled high (≥1 V) to activate regulator; floating prohibited. |
| 2,3 - GND | Power and signal ground | Dual ground pins reduce impedance path for high-frequency return currents; both must connect to PCB ground plane. |
| 4 - FB | Feedback input | Senses divided output voltage; connects to resistor divider (R1/R2) to set VOUT = 0.45 × (1 + R1/R2). |
| 5 - VOS | Output voltage sense | Direct connection to output node improves load regulation by compensating for PCB trace IR drop. |
| 6 - PG | Power good output | Open-drain output asserting low when VFB < 90% of 0.45 V; requires external pull-up to VOUT or bias rail. |
| 7 - SW | Switch node | Connects to inductor and high/low-side MOSFETs; carries high di/dt; requires short, low-inductance layout to minimize EMI. |
| 8 - VIN | Input power supply | Accepts 2.7–6 V; requires local 10-µF ceramic capacitor placed near pin for high-frequency decoupling. |
| Exposed Pad | Thermal & electrical ground | Mandatory solder connection to PCB ground plane; essential for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ Architecture | Enables sub-10-µs load transient response with <1% output deviation and eliminates need for external compensation components. |
| 100% Duty-Cycle Mode | Extends usable battery life by sustaining regulation down to VIN = VOUT + IOUT × (RDS(on) + RL), e.g., 0.9 V output from 1.0 V input at 1 A. |
| Output Discharge Function | Internally discharges VOUT through SW when EN = LOW, preventing residual voltage from interfering with downstream circuitry during shutdown. |
| Integrated MOSFETs | Eliminates external switch selection; 120 mΩ high-side and 90 mΩ low-side RDS(on) optimize conduction loss across 0.5–4 V output range. |
| Soft Start | 40-µs delay followed by 10 mV/µs ramp limits inrush current; supports safe startup into pre-biased outputs without reverse current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62084DSGT | Same pinout and electrical specs, but PG output is high-impedance (not active-low) during shutdown and fault conditions. | Requires external logic or pull-up configuration to detect fault states; unsuitable for direct PG-driven sequencing where low-level assertion is mandatory. | Select TLV62084ADSGT when PG=Low behavior is required for system-level fault signaling or cascaded enable sequencing. |
| TPS62084ADSGT | Same footprint and function, but higher 3-MHz switching frequency, lower 15-µA IQ, and tighter 0.45-V FB tolerance (±1%). | Supports smaller 0.47-µH inductors and faster transient response; better suited for noise-sensitive RF subsystems requiring lower ripple. | Choose TPS62084ADSGT for next-gen designs demanding lower IQ, higher frequency, or tighter output accuracy-verify layout compatibility with higher dv/dt. |
Compared with TLV62084DSGT, TLV62084ADSGT provides deterministic low-level PG assertion during faults-critical for fail-safe sequencing-while TPS62084ADSGT offers superior light-load efficiency and precision at the cost of increased EMI filtering requirements.

FAQ
What is the key functional difference between TLV62084ADSGT and TLV62084DSGT?
The TLV62084ADSGT features active-low Power Good (PG) logic: PG asserts low during output undervoltage, shutdown, UVLO, or thermal fault. In contrast, TLV62084DSGT's PG remains high-impedance in those states. This makes TLV62084ADSGT suitable for direct fault detection and rail sequencing without additional logic. Both share identical pinout, electrical specs, and package.
Does TLV62084ADSGT support startup into a pre-biased output?
Yes, TLV62084ADSGT supports startup into a pre-biased output capacitor. When EN is asserted, the device begins switching and ramps VOUT toward the programmed value without drawing reverse current from the pre-charged rail-enabling safe integration in multi-rail systems with staggered power-up sequences.
What is the recommended minimum output capacitance for TLV62084ADSGT?
Texas Instruments specifies a minimum 10-µF ceramic output capacitor (X5R/X7R) for TLV62084ADSGT, placed as close as possible to the VOS and GND pins. For optimal transient response and stability with DCS-Control™, 22 µF is recommended-especially at 2-A loads or when using the VOS pin for remote sensing.
How does the DCS-Control™ architecture improve transient performance in TLV62084ADSGT?
DCS-Control™ integrates the feedback loop, PWM modulator, and power stage into a single control structure with inherent fast-response characteristics. It achieves <10-µs load transient recovery and <±15 mV output deviation by directly controlling the on-time based on output voltage error-eliminating phase-margin concerns and external compensation networks required by traditional voltage-mode controllers.
Can TLV62084ADSGT operate with 100% duty cycle, and under what conditions?
Yes, TLV62084ADSGT enters 100% duty cycle when VIN approaches VOUT, turning on the high-side MOSFET continuously and disabling the low-side switch. This occurs automatically to maintain regulation-critical for maximizing battery runtime in single-cell Li-ion applications where input may dip to 2.7 V while powering a 2.5-V rail.
