Product details
Overview
TLV62150RGTT from Texas Instruments is a synchronous step-down DC-DC converter optimized for high power density applications, delivering up to 1-A continuous output current across an input range of 4 V to 17 V, with adjustable output voltage from 0.9 V to 5 V and DCS-Control™ topology for fast transient response. It operates at 2.5 MHz (FSW = Low) or 1.25 MHz (FSW = High), features Power Good output, 19 µA quiescent current in PWM mode, and 100% duty cycle capability for battery-powered systems.
For engineers reviewing the TLV62150RGTT datasheet, TLV62150RGTT pinout, TLV62150RGTT application, or TLV62150RGTT equivalent, key selection considerations include its 3×3 mm VQFN-16 package, seamless PWM-to-Power-Save-mode transition, programmable soft-start/tracking, and pin-selectable ±5% output voltage margining - all critical for POL supplies in mobile PCs, cameras, and building automation.
Technical Context
The TLV62150RGTT implements DCS-Control™ topology, combining direct output voltage sensing with a fast comparator-driven switching control loop and a compensated voltage feedback path for stable regulation. Its dual-mode operation - fixed-frequency PWM at 1.25/2.5 MHz and variable-frequency Power Save Mode - ensures high efficiency across 0–1 A load range without output voltage disturbance during mode transitions.
Functional integration includes internal high-side (90 mΩ) and low-side (40 mΩ) MOSFETs, undervoltage lockout (2.7 V threshold, 200 mV hysteresis), thermal shutdown (160°C), short-circuit protection, and open-drain Power Good with 92–98% rising threshold. The SS/TR pin enables monotonic startup into pre-biased rails and voltage tracking via external voltage source.

Pinout & Package
TLV62150RGTT is housed in a thermally enhanced 3.00 mm × 3.00 mm VQFN-16 package (RGT) with exposed thermal pad soldered to AGND/PGND for optimal power dissipation and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1,2,3) | Power input supply rail | Connects directly to high-current input source; must be decoupled locally to minimize switching noise injection. |
| SW (1,2,3) | Switch node | Drives external inductor; requires tight layout with minimal trace inductance to reduce ringing and EMI. |
| PGND (15,16) | Power ground return | Low-impedance path for high di/dt currents; must connect directly to exposed thermal pad and system ground plane. |
| AGND (6) | Analog ground reference | Reference for FB, VOS, and control circuitry; isolated from PGND except at single-point thermal pad connection. |
| FB (5) | Voltage feedback input | Senses output via resistive divider; high-impedance node requiring guard ring and shortest possible trace. |
| VOS (14) | Output voltage sense | Direct connection to output capacitor for accurate regulation under dynamic load; improves line/load regulation. |
| EN (13) | Enable control | Active-high logic input with internal 400 kΩ pull-down; enables power sequencing with other rails or microcontroller GPIO. |
| SS/TR (9) | Soft-start / tracking | External capacitor sets startup ramp time; voltage input enables output tracking of master supply for synchronized power-up. |
| DEF (8) | Output voltage scaling | Logic input selects nominal VOUT (DEF=Low) or +5% VOUT (DEF=High) for hardware margining or tolerance compensation. |
| FSW (7) | Frequency select | Logic input sets 2.5 MHz (Low) for compact size or 1.25 MHz (High) for higher efficiency and lower ripple. |
| PG (4) | Power good indicator | Open-drain output requiring external pull-up; signals valid regulation (high) or fault (high-impedance for TLV62150). |
| AVIN (10) | Analog supply input | Bias supply for control circuitry; must tie to same source as PVIN to avoid ground bounce in mixed-signal systems. |
Key Features

| Programmable soft-start & tracking | SS/TR pin supports both controlled startup (via capacitor) and real-time output voltage tracking of master rail - essential for FPGA/CPU core sequencing. |
| 100% duty cycle operation | Enables regulation when VIN approaches VOUT (e.g., 3.6 V → 3.3 V), extending usable battery voltage range by ~15% in Li-ion applications. |
| Pin-selectable output voltage | DEF pin toggles output between nominal and +5% without changing external resistor network - simplifies hardware validation and margin testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62150ARGTT | Same pinout and electrical specs, but PG output is active-low (not high-impedance) during shutdown/UVLO. | Required where active discharge of output rail is needed during fault conditions (e.g., safety-critical shutdown sequences). | Select TLV62150ARGTT if PG must drive external discharge FETs; otherwise TLV62150RGTT suffices for standard sequencing. |

FAQ
What is the recommended inductor value for TLV62150RGTT when operating at 2.5 MHz?
For TLV62150RGTT operating at 2.5 MHz (FSW = Low), Texas Instruments recommends a 1.0 µH to 2.2 µH shielded power inductor with saturation current ≥1.5 A. A 1.5 µH, 2.5 A saturation inductor (e.g., Coilcraft XAL5030-152MEB) delivers optimal balance of size, efficiency (>92% at 1 A), and transient response. Larger values increase ripple suppression but reduce transient speed; smaller values raise peak current stress on internal MOSFETs.
Does TLV62150RGTT support startup into a pre-biased output?
Yes, TLV62150RGTT supports monotonic startup into a pre-biased output. When EN is asserted, the low-side MOSFET remains off until the internal soft-start ramp exceeds the pre-bias voltage, preventing reverse current flow. This behavior is confirmed in the datasheet's Figure 32 and Section 8.3.2. No external components are required - the feature is inherent to the TLV62150RGTT's control architecture.
What is the maximum allowable voltage on the PG pin of TLV62150RGTT?
The maximum allowable voltage on the PG pin of TLV62150RGTT is 7 V, as specified in Absolute Maximum Ratings (Section 7.1). Since PG is an open-drain output, it must be pulled up to a voltage ≤7 V - typically to VOUT or a clean 3.3 V/5 V rail. Connecting PG directly to VIN (e.g., 12 V) risks permanent damage. TI recommends using a 10-kΩ pull-up to VOUT for robust sequencing.
How does the DEF pin affect output voltage accuracy in TLV62150RGTT?
The DEF pin on TLV62150RGTT shifts the internal reference by +5% when driven high, resulting in a proportional increase in regulated output voltage (e.g., 3.3 V → 3.465 V). Initial accuracy remains ±2.5% of the selected nominal value, so 3.465 V output has absolute tolerance of ±87 mV. This margining function is verified in Electrical Characteristics Table (Section 7.5) and enables hardware validation without resistor changes.
Can TLV62150RGTT operate with input voltage below 4 V?
No, TLV62150RGTT cannot operate reliably below 4 V input. Its undervoltage lockout (UVLO) activates at 2.7 V (typical), but the device only guarantees full specification compliance - including 1-A output, regulation accuracy, and DCS-Control™ stability - within the Recommended Operating Conditions range of 4 V to 17 V. Operation below 4 V may result in unregulated output, excessive dropout, or intermittent shutdown, as confirmed in Section 7.3 of the datasheet.
