Product details
Overview
TLV62085RLTR from Texas Instruments is a high-efficiency, 3-A synchronous step-down DC/DC converter in a 2-mm × 2-mm VSON-7 package, featuring DCS-Control™ topology, 2.5-V to 6.0-V input range, 0.8-V to VIN adjustable output, and up to 95% efficiency at 1 A–3 A loads - deployed in battery-powered portable electronics and point-of-load regulation.
For engineers reviewing the TLV62085RLTR datasheet, TLV62085RLTR pinout, TLV62085RLTR application, or TLV62085RLTR equivalent, key selection criteria include its 2.4-MHz PWM switching frequency, 17-μA quiescent current in light-load Power Save Mode, integrated 31-mΩ/23-mΩ MOSFETs, 100% duty cycle low-dropout capability, and open-drain power-good (PG) output with 95%/90% voltage thresholds.
Technical Context
The TLV62085RLTR implements DCS-Control™ architecture - a hybrid regulation scheme combining hysteretic, voltage-mode, and current-mode control for seamless transition between PWM and Power Save Mode (PFM). It operates at a nominal 2.4 MHz under medium-to-heavy loads and dynamically reduces switching frequency at light loads while maintaining tight output regulation.
Its internal compensation supports wide output capacitor ranges (10 µF–150 µF+), enabling excellent load transient response and low output ripple (<30 mV). The device integrates undervoltage lockout (2.2 V ±0.1 V), thermal shutdown (150 °C), hiccup-mode short-circuit protection, and output discharge via 260-Ω internal resistor when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 6.0 V - supports single-cell Li-ion, Li-polymer, and multi-cell alkaline/NiMH battery stacks without external regulators. |
| Output Current | Up to 3 A continuous - sufficient for core logic rails of microcontrollers, FPGAs, and DSPs in space-constrained designs. |
| Switching Frequency | 2.4 MHz (PWM mode) - enables use of sub-1-µH inductors and compact ceramic capacitors for minimal solution size (~62 mm²). |
| Quiescent Current | 17 µA - extends battery runtime in always-on or low-duty-cycle IoT sensors and wearables. |
| Efficiency Peak | 95% at 1–3 A - achieved via low RDS(on) (31 mΩ HS / 23 mΩ LS) and adaptive PFM/PWM mode switching. |
| Feedback Reference | 800 mV ±8 mV - allows precise output setting from 0.8 V to VIN using external resistor divider; supports 1.2 V, 1.8 V, and 3.3 V rails. |
| Power Good Threshold | 95% VOUT (assert), 90% VOUT (deassert) - provides reliable rail sequencing and system monitoring without external comparators. |
Pinout & Package
TLV62085RLTR uses a 7-pin VSON (RLT) package with 0.5-mm pitch and exposed thermal pad (pin 5 = GND). The package measures 2.00 mm × 2.00 mm × 0.85 mm and is optimized for high thermal performance on PCBs with copper pour under the die pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-high logic control; internal 400-kΩ pulldown ensures safe default-off state; <0.7 µA shutdown current minimizes battery drain. |
| PG (Pin 2) | Open-drain power-good output | Sinks up to 1 mA; requires external pullup ≤6 V; used for rail sequencing or host MCU status monitoring. |
| FB (Pin 3) | Feedback input | Connects to resistor divider midpoint; regulates output to 800 mV reference; leakage <0.01 µA avoids voltage error. |
| VOS (Pin 4) | Output voltage sense | Direct connection to output capacitor anode; improves load regulation accuracy by eliminating PCB trace IR drop. |
| GND (Pin 5) | Ground reference | Primary return path for power and signal; must be connected to low-impedance PCB ground plane for stability and EMI control. |
| SW (Pin 6) | Switch node | Connects to inductor and high-side/low-side MOSFET drains; high dv/dt node requiring short, wide traces and guard ring isolation. |
| VIN (Pin 7) | Input power supply | Accepts 2.5–6.0 V; requires local 10-µF ceramic capacitor placed adjacent to pin for high-frequency decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <1% load transient deviation and <10-µs recovery time without external compensation components. |
| 100% duty cycle operation | Extends usable battery life by sustaining regulation down to VIN = VOUT + IOUT×RDS(on), critical for deep-discharge Li-ion applications. |
| Hiccup short-circuit protection | Triggers after 32 overcurrent events, then auto-restarts every ~66 µs - prevents thermal runaway while allowing recovery from temporary faults. |
| Internal output discharge | 260-Ω resistor discharges VOUT when EN = LOW or during fault conditions - eliminates residual voltage that could disrupt downstream logic. |
| Soft-start time | 0.8 ms typical - limits inrush current into output capacitors and avoids brownout of weak input sources like coin cells. |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62085RLTR | Same pinout and footprint; higher 4-A rating, 2.2-MHz switching, and improved light-load efficiency (12 µA IQ). | Better suited for future-proofing or margin-critical 3.5-A peak loads; requires updated inductor selection due to lower fSW. | Select TPS62085RLTR if design requires >3 A headroom or lower quiescent current; verify thermal performance with new layout. |
| MP2143GJ-Z | 3-A, 2.2-MHz buck; no VOS pin, fixed 1.2-V option available; 25-mΩ/35-mΩ MOSFETs; lacks hiccup protection. | Lower BOM cost but reduced accuracy under PCB trace resistance; unsuitable for systems requiring guaranteed fault recovery. | Choose MP2143GJ-Z only for cost-sensitive consumer applications where PG sequencing and output discharge are non-critical. |
Compared with TPS62085RLTR, TLV62085RLTR trades peak current and ultra-low IQ for proven field reliability and simpler thermal management; versus MP2143GJ-Z, it delivers superior regulation accuracy, robust fault handling, and design flexibility via adjustable output and VOS sensing.

FAQ
What is the recommended input capacitor for TLV62085RLTR?
A 10-µF X7R ceramic capacitor rated ≥10 V, placed as close as possible between VIN and GND pins, is recommended for TLV62085RLTR. This value suppresses high-frequency input ripple generated by the 2.4-MHz switching action and ensures stable operation under dynamic load conditions. Larger values (e.g., 22 µF) further reduce input current ripple but are not required for basic functionality.
Does TLV62085RLTR support output voltages below 1.0 V?
Yes, TLV62085RLTR supports output voltages as low as 0.8 V, set by the feedback resistor divider according to VOUT = 0.8 V × (1 + R1/R2). For 0.9-V or 0.95-V outputs, precision resistors with ≤1% tolerance are recommended to maintain regulation accuracy within ±1.5%, as confirmed in the device's electrical characteristics table.
How does the VOS pin improve regulation accuracy in TLV62085RLTR?
The VOS pin in TLV62085RLTR provides remote output voltage sensing by connecting directly to the load side of the output capacitor. This compensates for IR drop across PCB traces and connectors, improving load regulation accuracy to ±0.5% over full current range - especially critical in high-current or long-trace applications where standard FB-only sensing would introduce >2% error.
Can TLV62085RLTR operate with a 2.3-V input supply?
No - TLV62085RLTR has a 2.5-V minimum input voltage per its absolute maximum ratings and recommended operating conditions. At 2.3 V, the device triggers undervoltage lockout (UVLO) and shuts down. Its UVLO threshold is 2.2 V ±0.1 V with 200-mV hysteresis, so reliable operation begins only above 2.4 V after startup.
What thermal derating applies to TLV62085RLTR at 125°C ambient?
At 125°C ambient, TLV62085RLTR's maximum continuous output current drops to ~2.1 A due to thermal limits. With RθJA = 107.8 °C/W and junction limit of 150°C, power dissipation must stay below 2.3 W. This is achievable with 2-layer PCBs having ≥2 in² copper pour under the VSON package and no additional airflow.
