Product details
Overview
TLV62150RGTR from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density POL applications. It operates from 4 V to 17 V input, delivers up to 1 A continuous output current, supports adjustable output voltage from 0.9 V to 5 V, features DCS-Control™ topology for fast transient response, and integrates power good (PG), soft-start/tracking (SS/TR), and frequency-select (FSW) pins - used in mobile PCs, tablets, and building automation systems.
For engineers reviewing the TLV62150RGTR datasheet, TLV62150RGTR pinout, TLV62150RGTR application, or TLV62150RGTR equivalent, key selection considerations include its 2.5 MHz (or 1.25 MHz) switching frequency, 19 µA quiescent current in Power Save Mode, 100% duty-cycle capability, integrated overtemperature and short-circuit protection, and compatibility with small 2.2 µH inductors and low-ESR ceramic capacitors.
Technical Context
The TLV62150RGTR implements DCS-Control™ - a hybrid regulation topology combining voltage-mode feedback with direct control of the output voltage ramp via an internal comparator, enabling stable operation with minimal external compensation. It supports seamless transition between PWM mode (fixed-frequency, continuous conduction) and Power Save Mode (variable-frequency, discontinuous conduction) without output voltage disturbance.
Its functional architecture includes dual MOSFET power switches (90 mΩ high-side, 40 mΩ low-side), programmable soft-start via external capacitor on SS/TR, open-drain PG with 92–98% rising threshold, and pin-selectable switching frequency (FSW = Low → ~2.5 MHz; FSW = High → ~1.25 MHz), all within a thermally enhanced 3 mm × 3 mm VQFN-16 package with exposed thermal pad.

Pinout & Package
TLV62150RGTR is housed in a 3.00 mm × 3.00 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND/PGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1,2,3) | Power input supply rail | High-current path for power stage; must be connected directly to input capacitor and share plane with PGND. |
| SW (1,2,3) | Switch node | Connection point for external inductor; carries high di/dt switching waveform - requires tight layout and Kelvin routing. |
| PG (4) | Power good indicator | Open-drain output signaling VOUT regulation status; requires external pull-up to ≤7 V for sequencing. |
| FB (5) | Voltage feedback input | Sense point for resistive divider; sets output voltage with ±1% initial accuracy and <0.05%/A load regulation. |
| AGND (6) | Analog ground reference | Reference for control circuitry; must connect directly to exposed thermal pad and common ground plane. |
| FSW (7) | Frequency select input | Logic-controlled pin: Low → ~2.5 MHz, High → ~1.25 MHz - affects efficiency vs. ripple trade-off. |
| DEF (8) | Output voltage scaling | Logic input: Low → nominal VOUT, High → VOUT +5% - enables margining for system-level voltage tolerance testing. |
| SS/TR (9) | Soft-start / tracking input | Capacitor-programmable startup ramp or master-voltage follower - prevents inrush and enables monotonic power-up. |
| VOS (14) | Output voltage sense | Direct connection to output rail for precise loop sensing; improves regulation under PCB trace resistance. |
| EN (13) | Enable control | Active-high logic input with internal 400 kΩ pull-down - allows controlled start-up and multi-rail sequencing. |
| AVIN (10) | Analog supply input | Low-noise supply for control circuitry; must tie to same source as PVIN but routed separately for noise isolation. |
| PGND (15,16) | Power ground return | High-current return path for power switches; must connect directly to exposed thermal pad and minimize loop area. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables fast transient response (<10 µs recovery) and stable regulation with only 22 µF ceramic output capacitance - no external compensation required. |
| Seamless Power Save Mode | Maintains >85% efficiency at 1 mA load while automatically transitioning between PWM and variable-frequency operation - no control signal needed. |
| Programmable soft-start | External capacitor on SS/TR pin sets output ramp time from <1 ms to >100 ms - eliminates inrush current into large downstream capacitance. |
| 100% duty-cycle operation | Allows regulation down to VIN − VOUT ≈ 150 mV (e.g., 3.45 V → 3.3 V), extending runtime in battery-powered systems near end-of-discharge. |
| Integrated protection suite | Combines thermal shutdown (160°C), UVLO (2.7 V), short-circuit limiting (~1.7 A peak), and overvoltage clamping - reduces need for external fault management circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62150ARGTR | Same pinout and electrical specs, but PG output is active-low (not high-impedance) during shutdown - requires different pull-up strategy. | Better suited for systems requiring active discharge of VOUT during fault or sequencing. | Select TLV62150ARGTR only if PG low-state behavior is explicitly required; otherwise TLV62150RGTR offers broader compatibility with legacy designs. |
| TPS62150ARGTR | Pin-to-pin compatible with improved features: lower IQ (12 µA), tighter VOUT accuracy (±0.5%), and higher current limit (1.8 A). | Preferred for new designs targeting longer battery life and tighter regulation margins. | TPS62150ARGTR is a drop-in upgrade for TLV62150RGTR where enhanced efficiency and accuracy justify BOM revision. |
Compared with TLV62150ARGTR, the TLV62150RGTR provides high-impedance PG during shutdown - simplifying sequencing in multi-rail systems without active discharge needs. Against TPS62150ARGTR, it trades slightly higher quiescent current and looser output accuracy for established qualification and cost-sensitive volume production.

FAQ
What is the recommended inductor value for TLV62150RGTR when operating at 2.5 MHz?
The TLV62150RGTR datasheet specifies a 1 µH to 2.2 µH inductor for 2.5 MHz operation. A 1.5 µH, 2.5 A saturation-current shielded inductor with ≤50 mΩ DCR is optimal - it balances peak current handling, size, and efficiency. Using 1 µH yields faster transient response but higher ripple; 2.2 µH reduces ripple and EMI at the cost of slightly slower load steps. Always verify saturation margin at 1.7 A peak current per Electrical Characteristics.
Does TLV62150RGTR support pre-biased output startup?
Yes, TLV62150RGTR supports monotonic pre-biased startup: when enabled into a pre-charged output, the low-side MOSFET remains off until the internal soft-start ramp exceeds the existing VOUT, preventing reverse current flow. This behavior is confirmed in Section 8.3.2 and Figure 32 of the SLVSB71E datasheet. No external diode or circuitry is required - the feature is inherent to the DCS-Control™ architecture and gate drive logic.
How does the TLV62150RGTR handle thermal overload conditions?
TLV62150RGTR monitors junction temperature via an internal sensor. If TJ exceeds 160°C (typical), it enters thermal shutdown: both high- and low-side MOSFETs turn off, PG goes high-impedance, and switching halts. Once TJ falls below 140°C (160°C − 20°C hysteresis), the device restarts with full soft-start sequence. This behavior is specified in Section 7.5 (TSD = 160°C) and Section 8.3.7, and is independent of EN state or input voltage.
Can TLV62150RGTR operate with input voltage below 4 V?
No - the absolute minimum input voltage for functional operation is 4 V, per Recommended Operating Conditions (Section 7.3). Below 4 V, the device may not regulate due to undervoltage lockout activation (VUVLO falling threshold = 2.7 V), and internal bias rails become unstable. While UVLO releases at ~2.9 V (2.7 V + 200 mV hysteresis), sustained operation below 4 V is outside specification and risks erratic behavior, especially under load. For sub-4 V inputs, consider TI's TPS6208x or similar low-VIN buck converters.
What is the maximum allowable voltage on the PG pin of TLV62150RGTR?
The maximum voltage on the PG pin is 7 V, as defined in Absolute Maximum Ratings (Section 7.1). Exceeding this risks permanent damage to the open-drain structure. TI recommends pulling PG to VOUT (≤5 V) or another regulated rail ≤7 V using a 10–100 kΩ resistor. Connecting PG directly to VIN (up to 17 V) violates the absolute max rating and must be avoided. The PG sink capability is rated for 2 mA at VOL ≤ 0.3 V, per Section 7.5.
