Product details
Overview
TLV62095RGTR 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), up to 95% efficiency at 3 A, 1.4 MHz switching frequency, and 20 µA quiescent current in Power Save Mode - used in SSDs, HDDs, and portable computing power rails.
For engineers reviewing the TLV62095RGTR datasheet, TLV62095RGTR pinout, TLV62095RGTR application, or TLV62095RGTR equivalent, key selection criteria include its 16-pin VQFN package, hiccup-mode short-circuit protection, output discharge function, soft-start control via external capacitor, and compatibility with 10–150 µF output capacitors for load-transient-stable point-of-load regulation.
Technical Context
The TLV62095RGTR implements DCS-Control™ - a hybrid regulation architecture combining hysteretic response speed with voltage-mode stability - enabling seamless PWM-to-Power-Save transition without output voltage disturbance. It uses an internal charge pump (CP/CN pins) to drive both high-side (50 mΩ RDS(on)) and low-side (40 mΩ RDS(on)) MOSFETs.
Functional modes include 100% duty-cycle low-dropout operation, ratiometric or coincidental voltage tracking via the SS pin, open-drain PG output with 90–95% VOUT threshold, and thermal shutdown at 150°C with 20°C hysteresis. The device enters shutdown at <2.2 V UVLO and draws only 0.6 µA ISD.
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 - sustains full load without thermal derating in 3 mm × 3 mm VQFN with exposed thermal pad. |
| Switching Frequency | 1.4 MHz typical - enables compact 1 µH inductor and ceramic output filter (10–150 µF). |
| Efficiency | Up to 95% at 3 A - achieved via synchronous rectification and low RDS(on) FETs (50/40 mΩ). |
| Quiescent Current | 20 µA in Power Save Mode - extends battery life in always-on subsystems (e.g., SSD standby). |
| Feedback Reference | 800 mV ±8 mV - enables precise 1.2 V, 1.8 V, or 2.6 V outputs using standard resistor dividers. |
| Protection Features | Hiccup-mode overcurrent, thermal shutdown (150°C), UVLO (2.2 V), and output discharge (200 Ω). |
Pinout & Package
TLV62095RGTR is housed in a 3 mm × 3 mm, 16-pin VQFN package with exposed thermal pad soldered to AGND for thermal reliability.
| 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 regulation. |
| PG (4) | Open-drain power-good flag | Sinks ≤1 mA; requires external pull-up ≤VIN; asserts high when VFB ≥95% of target. |
| FB (5) | Voltage feedback input | Monitors resistive divider output; sets VOUT = 0.8 V × (1 + R1/R2). |
| AGND (6) | Analog ground reference | Separate from PGND; connects to thermal pad and analog circuitry to minimize noise coupling. |
| CP / CN (7, 8) | Charge pump flying capacitor terminals | Require 10 nF X7R capacitor; enables gate drive for high-side FET without external supply. |
| SS (9) | Soft-start timing control | Charged by 7.5 µA current; capacitor value sets startup ramp time - also enables voltage tracking. |
| AVIN (10) | Analog supply input | Powers internal bandgap and error amplifier; must be bypassed with 100 nF ceramic capacitor. |
| PVIN (11, 12) | Power input supply | High-current VIN path; decoupled with ≥22 µF ceramic capacitor close to pins. |
| EN (13) | Enable control | Active-high; internal 400 kΩ pull-down ensures default disable; 0.65 V min high-level threshold. |
| PGND (14, 15) | Power ground return | Low-impedance path for switch current; separate copper pour from AGND, joined at single point. |
| VOS (16) | Output voltage sense | Direct connection to VOUT node; enables accurate remote sensing and activates 200 Ω discharge on shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <10 µs load transient response and <±0.5% line/load regulation across temperature. |
| Adjustable soft-start | Capacitor-programmable startup time prevents inrush current - critical for multi-rail sequencing in SSDs. |
| Output voltage tracking | SS pin accepts external voltage ramp to coordinate power-up/down with other rails (e.g., core + I/O). |
| 100% duty-cycle mode | Maintains regulation down to VIN – VOUT ≈ IOUT × (50 mΩ + LDCR) - maximizes runtime in battery-powered systems. |
| Integrated output discharge | 200 Ω internal FET discharges VOUT on EN low or fault - eliminates need for external bleed circuitry. |

FAQ
What is the maximum output current capability of the TLV62095RGTR?
The TLV62095RGTR is rated for 4 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its 5.5 A hiccup-mode current limit and 50/40 mΩ FETs support brief peak loads beyond 4 A, but sustained operation above 4 A requires careful thermal validation using the device's RθJA = 47°C/W and junction temperature monitoring. The TLV62095RGTR datasheet specifies 4 A as the guaranteed continuous rating.
Does the TLV62095RGTR support output voltage tracking, and how is it implemented?
Yes, the TLV62095RGTR supports both ratiometric and coincidental output voltage tracking via its SS (soft-start) pin. An external voltage source drives the SS pin, and the internal reference follows it with a 1.56× scaling factor until reaching 0.8 V. This enables coordinated power-up/down with other rails - for example, using a resistor divider from a master supply to track 1.8 V to 3.3 V. The TLV62095RGTR datasheet Figure 5 and Section 7.4.3 detail implementation constraints, including SS pin voltage limits (≤7 V) and R2 sizing guidance.
What is the purpose of the VOS pin on the TLV62095RGTR, and how must it be connected?
The VOS (voltage output sense) pin on the TLV62095RGTR provides direct connection to the output voltage node for accurate remote sensing and enables the integrated 200 Ω output discharge function. It must be connected directly to the VOUT net - not through any resistance or filter - to ensure regulation accuracy and proper discharge activation during shutdown, UVLO, or thermal fault. Leaving VOS unconnected disables discharge and degrades load regulation; the TLV62095RGTR datasheet explicitly requires this connection in Pin Functions Table and Section 7.4.5.
How does the TLV62095RGTR achieve high efficiency at light loads?
The TLV62095RGTR achieves high light-load efficiency via automatic transition into Power Save Mode, which reduces switching frequency and cuts quiescent current to 20 µA. Unlike fixed-frequency PWM-only converters, its DCS-Control™ topology maintains regulation while minimizing gate-drive and switching losses. Efficiency remains >80% down to 10 mA load (per Figure D017–D019), enabled by seamless mode transition and low RDS(on) FETs. This behavior is intrinsic to the TLV62095RGTR's control architecture and requires no external configuration.
Is the TLV62095RGTR pin-compatible with other devices in its family, and what are the implications?
Yes, the TLV62095RGTR is pin-to-pin compatible with TLV62090RGTR and TPS62095RGTR per the TLV62095RGTR datasheet Features section. This allows direct replacement in existing layouts - though functional differences exist: TLV62090RGTR lacks VOS and PG pins and is rated for 3 A, while TPS62095RGTR offers higher efficiency (96%), lower IQ (15 µA), and tighter VFB tolerance. System validation is still required when swapping, as the TLV62095RGTR's specific thermal and transient behavior must be confirmed in the target application.
