Product details
Overview
TLV62595DMQR from Texas Instruments is a 4-A synchronous step-down DC/DC converter with DCS-Control™ topology, 2.5-V to 5.5-V input range, 0.6-V to 4-V adjustable output, 1% feedback voltage accuracy over –40°C to 125°C, and 2.2-MHz switching frequency - optimized for compact power delivery in space-constrained SSDs and IP cameras.
For engineers reviewing the TLV62595DMQR datasheet, TLV62595DMQR pinout, TLV62595DMQR application, or TLV62595DMQR equivalent, key selection considerations include its 1.5-mm × 1.5-mm QFN-6 package, active output discharge, power-good open-drain signal, 10-μA quiescent current in PSM mode, and thermal shutdown with 150°C trip point.
Technical Context
The TLV62595DMQR employs adaptive constant-on-time DCS-Control™ architecture to deliver fast transient response and stable regulation across load and line variations. It operates in PWM mode at medium-to-heavy loads (≥2 A) and seamlessly transitions to Power Save Mode (PSM) below ~0.5 A, maintaining >85% efficiency down to 100 μA load.
Its integrated 26-mΩ high-side and 25-mΩ low-side MOSFETs enable high-efficiency operation up to 4 A, while 100% duty-cycle capability supports ultra-low dropout operation near VIN ≈ VOUT. The device includes HICCUP short-circuit protection, undervoltage lockout (2.2 V ±160 mV), and internal soft-start (1.75 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion, USB PD, and industrial 3.3-V/5-V rails. |
| Output Current | Up to 4 A continuous - sufficient for core logic rails in SSD controllers and SoC subsystems. |
| Feedback Accuracy | ±1% over –40°C to 125°C - ensures tight output regulation without external trimming. |
| Switching Frequency | 2.2 MHz typical - enables use of sub-1-μH inductors and small ceramic capacitors for minimal footprint. |
| Quiescent Current | 10 μA in PSM - extends battery life in always-on portable electronics and network cameras. |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design. |
| Power Good Output | Open-drain PG with 100-μs blanking and 20-μs deglitch - enables reliable rail sequencing in multi-converter systems. |
Pinout & Package
TLV62595DMQR is housed in a thermally enhanced 6-pin VSON-HR (DMQ) package measuring 1.5 mm × 1.5 mm × 0.55 mm, with exposed thermal pad for efficient heat dissipation in high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; threshold ~0.9 V (VIH), ~0.7 V (VIL); must not float. |
| PG | Power-good open-drain output | Sinks up to 1 mA; requires external pullup ≤5.5 V; asserts after soft-start and VFB ≥96% of target. |
| FB | Feedback input | Connects to resistor divider for adjustable output; internal 600-mV reference enables 0.6–4-V range. |
| GND | Power and signal ground | Common return path for control circuitry and power switches; ties to thermal pad. |
| SW | Switch node | Drives external inductor; carries high di/dt; requires tight layout and low-inductance routing. |
| VIN | Input power supply | Accepts 2.5–5.5 V; decoupled with ≥4.7-μF ceramic capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Delivers <10-μs load transient response with minimal output capacitance - critical for burst-mode processors. |
| Active output discharge | Discharges VOUT via SW pin when EN = low - prevents floating outputs and enables safe hot-swap or sequencing. |
| 100% duty-cycle operation | Maintains regulation with VIN as low as VOUT + IOUT × RDS(on)_HS + IOUT × DCR_L - ideal for low-dropout backup rails. |
| HICCUP short-circuit protection | Limits fault energy by cycling on/off for 100 μs per hiccup - avoids thermal runaway during sustained shorts. |
| WEBENCH® integration | Full parametric design support including BOM generation, thermal simulation, and CAD export - accelerates time-to-prototype. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6286418RTER | 3-A rated, 1.8-V fixed output, 2.5-V to 5.5-V input, 1.5-MHz switching, no PG pin | Lacks power-good signaling and 4-A capability; suitable only for lower-current fixed-output use cases | Select if system requires simpler fixed-output design and PG sequencing is handled externally |
| MP2155GQZ-P | 4-A rated, 2.5-V to 5.5-V input, 0.6–5-V adjustable output, 2-MHz switching, no active discharge | Missing active output discharge and has higher 25-μA IQ; thermal shutdown at 160°C | Choose when board-level discharge is implemented externally and slightly higher IQ is acceptable |
Compared with TPS6286418RTER and MP2155GQZ-P, the TLV62595DMQR uniquely combines 4-A capability, 1% accuracy, active discharge, PG signaling, and 10-μA quiescent current in a 1.5-mm × 1.5-mm footprint - making it optimal for thermally constrained, multi-rail embedded systems requiring high confidence in startup and fault behavior.

FAQ
What is the maximum output current capability of the TLV62595DMQR?
The TLV62595DMQR delivers up to 4 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, adequate PCB copper, and proper thermal layout). Its current limit is internally set to 4.8–5.6 A, but sustained 4-A operation requires attention to thermal derating - especially above 60°C ambient - due to its 129.5°C/W junction-to-ambient thermal resistance in standard layouts.
Does the TLV62595DMQR support adjustable output voltage, and how is it configured?
Yes, the TLV62595DMQR supports adjustable output voltage from 0.6 V to 4.0 V using an external resistor divider connected to the FB pin. The feedback reference is 600 mV ±1%, so VOUT = 0.6 V × (1 + R1/R2). R2 should be ≤100 kΩ for optimal light-load efficiency and noise immunity; a 120-pF feedforward capacitor (C3) is recommended when R2 = 100 kΩ.
What protection features does the TLV62595DMQR include?
The TLV62595DMQR integrates multiple protection mechanisms: HICCUP-mode short-circuit protection (limits fault energy), thermal shutdown (150°C trip with 20°C hysteresis), undervoltage lockout (2.2 V ±160 mV), and active output discharge during disable. It also features cycle-by-cycle current limiting and soft-start (1.75 ms) to prevent inrush current damage.
Can the TLV62595DMQR operate with 100% duty cycle, and what is the minimum input voltage required?
Yes, the TLV62595DMQR supports 100% duty-cycle operation to minimize dropout when VIN approaches VOUT. The minimum input voltage is calculated as VIN,MIN = VOUT + IOUT,MAX × (RDS(on)_HS + DCR_L). For example, at 4 A and 1.8 V out, with 26 mΩ HS-FET and 10 mΩ inductor DCR, VIN,MIN ≈ 1.8 V + 4 A × 36 mΩ = 1.944 V - well within its 2.5-V minimum rating.
Is the TLV62595DMQR compatible with WEBENCH® Power Designer?
Yes, the TLV62595DMQR is fully supported in TI's WEBENCH® Power Designer tool. Engineers can enter input/output specifications, generate complete schematics and BOMs, simulate efficiency and thermal performance, optimize for footprint or cost, and export designs to popular CAD formats - all validated against the official TLV62595DMQR electrical model and layout guidelines.
