Product details
Overview
TLV62585RWTR from Texas Instruments is a 3-A synchronous buck DC-DC converter in a 2-mm × 2-mm QFN-12 package, delivering up to 95% efficiency at 1.8 V/3 A output with 2.5–5.5 V input range, 1.5-MHz fixed-frequency PWM operation, and integrated 56 mΩ/32 mΩ power switches for compact point-of-load power delivery in space-constrained battery-powered systems.
For engineers reviewing the TLV62585RWTR datasheet, TLV62585RWTR pinout, TLV62585RWTR application, or TLV62585RWTR equivalent, key selection considerations include its adaptive off-time peak-current control architecture, Power Save Mode for light-load efficiency, 100% duty-cycle low-dropout capability, soft-start timing (900 µs), and integrated thermal shutdown and hiccup-mode short-circuit protection.
Technical Context
The TLV62585RWTR implements an adaptive off-time peak-current control scheme that maintains stable 1.5-MHz switching frequency across varying input voltage (2.5–5.5 V), output voltage (0.6–VIN), and load current (0–3 A). Its internal compensation eliminates external compensation components.
It operates in PWM mode at medium-to-heavy loads and automatically transitions to Power Save Mode (PSM) at light loads to sustain high efficiency, with quiescent current of 35 µA and shutdown current below 2 µA. The device supports pre-biased start-up and includes integrated output discharge via SW pin during disable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3 A continuous - supports high-current SoC/FPGA core rails without external current boosting |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, USB, and 3.3-V/5-V system rails |
| Switching Frequency | 1.5 MHz typical - enables use of small 1-µH inductors and ceramic capacitors for minimal footprint |
| Efficiency | Up to 95% at 1.8 V/3 A - reduces thermal load and extends battery runtime in portable devices |
| RDS(on) | 56 mΩ (HS) / 32 mΩ (LS) - lowers conduction loss and improves full-load efficiency vs. discrete FET solutions |
| Quiescent Current | 35 µA - preserves battery life in always-on or low-power standby modes |
| Feedback Reference | 600 mV ±1% (0°C to 85°C) - enables precise output regulation with standard resistor dividers |
Pinout & Package
TLV62585RWTR is housed in a thermally enhanced 2.00 mm × 2.00 mm QFN-12 package with exposed thermal pad (PGND-connected) for improved heat dissipation in high-current applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (1,10) | Power Input | Dual-input pins reduce trace resistance and inductance; accept 2.5–5.5 V supply with UVLO at 2.45 V |
| SW (2,11) | Switch Node | Connects to inductor and internal HS/LS FETs; requires tight layout to minimize EMI and ringing |
| PGND (3,12) | Power Ground | High-current return path for switch node; must be tied directly to thermal pad and bulk capacitor ground |
| AGND (4) | Analog Ground | Reference for feedback and control circuitry; isolated from PGND to avoid noise coupling into FB loop |
| NC (5,6) | No Connection | Internally unconnected; leave floating or tie to AGND for mechanical stability (not for signal routing) |
| FB (7) | Feedback Input | Monitors output via resistor divider; 600-mV reference enables adjustable VOUT from 0.6 V to VIN |
| EN (8) | Enable Input | Active-high logic control; <0.4 V disables device (<2 µA shutdown current), >1.2 V enables operation |
| PG (9) | Power Good Output | Open-drain status flag; asserts high-Z when VOUT ≥95% nominal, pulls low when ≤90%; requires external pull-up ≤5.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Switches | 56-mΩ HS and 32-mΩ LS MOSFETs eliminate external FETs and gate drivers, reducing BOM count and layout complexity |
| Adaptive Off-Time Control | Maintains near-constant 1.5-MHz switching frequency across input/output/load variations-simplifies EMI filtering design |
| Power Save Mode (PSM) | Automatically engages at light load to reduce switching frequency and quiescent current, sustaining >85% efficiency down to 1 mA |
| 100% Duty Cycle Operation | Enables ultra-low dropout (e.g., 1.8 V out from 1.95 V in at 3 A), critical for battery end-of-discharge operation |
| Hiccup-Mode Short-Circuit Protection | Triggers after 32 overcurrent events, then cycles on/off with 500-µs delay-prevents thermal runaway without latch-off |
| Internal Soft Start | 900-µs ramp time limits inrush current and prevents brownout of weak input sources like coin cells or aging batteries |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62865RQYR | Higher 6-A rating, 2.5–5.5 V input, 1.8-V fixed output, 2-MHz switching, lower 25-µA IQ | Fixed-output variant; lacks adjustable FB and 100% duty cycle mode | Choose for higher current headroom and lower quiescent current where output voltage is fixed and dropout margin is sufficient |
| MP2451DT-LF-Z | 3-A rating, 4.5–26 V input, 1.5-MHz switching, external compensation, no PSM or PG | Wider input range but no light-load efficiency optimization or power-good signaling | Choose for industrial 12-V/24-V input systems requiring ruggedness over battery-life optimization |
Compared with TPS62865RQYR and MP2451DT-LF-Z, the TLV62585RWTR uniquely balances ultra-compact QFN-12 packaging, adjustable output, 100% duty cycle, and integrated PSM-making it optimal for space- and battery-limited 1.8-V/3-A applications where flexibility and efficiency across load range are critical.

FAQ
What is the maximum output current supported by the TLV62585RWTR?
The TLV62585RWTR supports up to 3 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its internal 56-mΩ high-side and 32-mΩ low-side MOSFETs enable this rating while maintaining high efficiency. Derating is required above 85°C ambient or with insufficient copper area; thermal metrics (RθJA = 95.7°C/W) confirm suitability for 3-A operation in typical 2-layer board layouts with thermal pad soldering.
Does the TLV62585RWTR support adjustable output voltage?
Yes, the TLV62585RWTR supports adjustable output voltage from 0.6 V to VIN using an external resistor divider connected to the FB pin. Its precision 600-mV ±1% feedback reference (0°C to 85°C) enables accurate regulation-e.g., setting 1.8 V with R1 = 200 kΩ and R2 = 100 kΩ. R2 must not exceed 100 kΩ to maintain light-load efficiency and noise immunity, as specified in the TLV62585RWTR datasheet.
How does the TLV62585RWTR handle short-circuit conditions?
The TLV62585RWTR employs hiccup-mode short-circuit protection: upon detecting 32 consecutive overcurrent events (ILIM ≈ 4.3 A), it disables switching for ~500 µs, then attempts restart. This cycle repeats until fault clears. Unlike latch-off protection, hiccup mode prevents thermal runaway while allowing automatic recovery-critical for systems where manual reset is impractical. The TLV62585RWTR also includes thermal shutdown (150°C) as a secondary safeguard.
Can the TLV62585RWTR start up into a pre-biased output?
Yes, the TLV62585RWTR supports pre-biased start-up: when enabled, it senses the existing output voltage and ramps toward the target VOUT without forcing reverse current into the output capacitor. This avoids damaging downstream circuitry or causing bus contention in multi-rail systems. The TLV62585RWTR achieves this via controlled gate drive sequencing and internal current limiting-confirmed in functional testing per SLVSDE5F revision November 2019.
What package type and pin count does the TLV62585RWTR use?
The TLV62585RWTR uses a 2.00 mm × 2.00 mm QFN-12 package with wettable flanks and an exposed thermal pad connected to PGND. It has 12 pins: dual VIN (1,10), dual SW (2,11), dual PGND (3,12), AGND (4), NC (5,6), FB (7), EN (8), and PG (9). This package enables high power density and superior thermal performance versus SOT-563 variants (e.g., TLV62585DRL), making it ideal for thermally demanding 3-A applications.
