Product details
Overview
TLV62095RGTT from Texas Instruments is a 4-A synchronous step-down DC/DC converter with DCS-Control™ topology, operating from 2.5 V to 5.5 V input and delivering adjustable output (0.8 V to VIN), achieving up to 95% efficiency at 1.4 MHz switching frequency. It features power save mode, 20 µA quiescent current, hiccup short-circuit protection, and output discharge - deployed in SSDs, HDDs, and portable computing systems.
For engineers reviewing the TLV62095RGTT datasheet, TLV62095RGTT pinout, TLV62095RGTT application, or TLV62095RGTT equivalent, key selection criteria include input voltage range (2.5–5.5 V), output current capability (4 A), thermal performance (RθJA = 47 °C/W), soft-start programmability, and compatibility with ceramic output capacitors from 10 µF to 150 µF.
Technical Context
The TLV62095RGTT implements DCS-Control™ - a hybrid regulation architecture combining hysteretic and voltage-mode control for seamless PWM-to-Power-Save transition without output disturbance. Its fixed on-time control enables stable operation across wide input/output ratios and load transients.
It integrates dual MOSFET power switches (RDS(on) = 50 mΩ high-side, 40 mΩ low-side), internal charge pump (CP/CN pins), and precision 0.8 V feedback reference with ±0.8% initial accuracy. Power sequencing is supported via EN and open-drain PG pins, while VOS enables direct output voltage sensing and discharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion, USB, and wide-input industrial rails. |
| Output Current | 4 A continuous - sufficient for core logic rails in SSDs and embedded processors. |
| Switching Frequency | 1.4 MHz typical - enables compact 1 µH inductors and reduces EMI filtering burden. |
| Efficiency | Up to 95% at 3.3 VIN/1.8 VOUT/3 A - minimizes thermal load in space-constrained designs. |
| Quiescent Current | 20 µA in Power Save Mode - extends battery runtime during light-load standby. |
| Feedback Reference | 0.800 V ±8 mV - enables precise output regulation with <0.1% line/load drift. |
| Thermal Shutdown | 150 °C with 20 °C hysteresis - protects against sustained overload or poor PCB thermal design. |
| Package | VQFN-16 (3.0 mm × 3.0 mm) with exposed thermal pad - optimized for high-power density and thermal dissipation. |
Pinout & Package
The TLV62095RGTT is housed in a 3.0 mm × 3.0 mm, 16-pin VQFN package with an exposed thermal pad soldered to AGND for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2) | Power switch node | Connects to external inductor; carries high di/dt switching current - requires tight layout and Kelvin connection. |
| DEF (3) | Internal logic enable | Must be tied to AVIN; floating or incorrect bias disables internal regulation circuitry. |
| PG (4) | Open-drain power-good indicator | Sinks ≤1 mA when VFB < 90% of target; requires external pull-up ≤VIN for system sequencing. |
| FB (5) | Feedback input | Monitors output via resistor divider; sets VOUT = 0.8 V × (1 + R1/R2); sensitive to noise - needs local bypass. |
| AGND (6) | Analog ground reference | Separate from PGND; connects to thermal pad and analog circuitry - critical for PSRR and stability. |
| CP/CN (7,8) | Charge pump flying capacitor terminals | Requires 10 nF X7R capacitor between pins; powers gate driver - no other connections permitted. |
| SS (9) | Soft-start timing control | Charged by 7.5 µA current; sets startup ramp time - floating yields ~50 µs minimum ramp. |
| AVIN (10) | Analog supply input | Powers internal bandgap and error amplifier; must be decoupled with ≥1 µF ceramic capacitor. |
| PVIN (11,12) | Power input supply | High-current path for input voltage; connects to bulk input capacitor - separate from AVIN for noise isolation. |
| EN (13) | Enable control | Active-high with 400 kΩ internal pull-down; logic high >0.65 V enables converter; low disables with 0.6 µA shutdown current. |
| PGND (14,15) | Power ground return | High-current return for SW node and internal FETs - must be solid copper plane under IC with multiple vias to AGND. |
| VOS (16) | Output voltage sense | Direct connection to output rail; enables accurate remote sensing and controlled discharge via 200 Ω internal resistor. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <1% load transient deviation and seamless PWM-to-Power-Save transition without output voltage glitch. |
| Adjustable soft-start | Programmable startup time via SS pin capacitor - prevents inrush current and avoids hiccup-mode triggering during cold start. |
| Output voltage tracking | SS pin accepts external voltage source to coordinate power-up/down sequencing with other rails (ratiometric or coincidental). |
| Hiccup short-circuit protection | 32-cycle fault counter with 66 µs recovery delay - limits average power dissipation during sustained shorts. |
| 100% duty cycle operation | Extends battery life by maintaining regulation down to VIN = VOUT + IOUT × (RDS(on) + RL) - critical for deep-discharge Li-ion use. |
| Integrated output discharge | 200 Ω internal resistor discharges VOUT on shutdown - ensures clean reset and prevents back-powering of downstream circuitry. |

FAQ
What is the maximum output current capability of the TLV62095RGTT?
The TLV62095RGTT delivers up to 4 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its internal FETs have RDS(on) of 50 mΩ (high-side) and 40 mΩ (low-side), and hiccup-mode current limiting activates at 4.7–5.5 A. Sustained 4-A operation requires adequate copper area and airflow per the 47 °C/W RθJA spec.
Does the TLV62095RGTT support adjustable output voltage, and how is it configured?
Yes, the TLV62095RGTT supports adjustable output from 0.8 V to VIN using an external resistor divider on the FB pin. With a precise 0.800 V internal reference, VOUT = 0.8 V × (1 + R1/R2). For a 1.8 V output, typical values are R2 = 160 kΩ and R1 = 200 kΩ. Feedback current should be ≥5 µA for noise immunity and accuracy.
How does the TLV62095RGTT manage efficiency at light loads?
The TLV62095RGTT automatically enters Power Save Mode below discontinuous conduction threshold, reducing switching frequency and drawing only 20 µA quiescent current. This maintains >80% efficiency even at 1 mA load, unlike fixed-frequency PWM-only converters. The seamless DCS-Control™ transition avoids output voltage perturbation during mode switching.
What is the role of the VOS pin on the TLV62095RGTT, and why is it required?
The VOS pin on the TLV62095RGTT provides direct output voltage sensing and enables the internal 200 Ω discharge path during shutdown. It must be connected directly to the output rail - not through traces or filters - to ensure accurate regulation and rapid, controlled discharge of output capacitance when EN is low or fault conditions occur.
Can the TLV62095RGTT be used in a power supply that requires strict sequencing with other rails?
Yes, the TLV62095RGTT supports robust power sequencing via its EN and PG pins. EN enables/disables the converter with active-pull-down logic, while the open-drain PG pin signals valid regulation (high-impedance when VFB ≥95% of target). Combined with SS pin voltage tracking, it enables ratiometric or coincidental startup/shutdown with companion supplies.
