Product details
Overview
TPS629206DRLR from Texas Instruments is a 600-mA, 3-V to 17-V synchronous buck converter with DCS-Control topology, 4-µA typical quiescent current, ±1% output voltage accuracy, and configurable 1-MHz or 2.5-MHz switching frequency. It delivers regulated power in space-constrained industrial and infrastructure systems requiring high light-load efficiency and precise enable control.
For engineers reviewing the TPS629206DRLR datasheet, TPS629206DRLR pinout, TPS629206DRLR application, or TPS629206DRLR equivalent, this page provides verified technical context, validated pin functions, confirmed package mapping (SOT-5X3, 0.5-mm pitch), real-world application constraints, and two rigorously validated alternative parts for design flexibility.
Technical Context
The TPS629206DRLR implements TI's DCS-Control architecture-combining fast transient response via direct voltage feedback comparison with stable DC regulation through an internally compensated loop. It supports seamless PWM/PFM transition and automatic efficiency enhancement (AEE) that dynamically adjusts switching frequency based on VIN and VOUT to maintain high efficiency across load range.
Its MODE/S-CONF pin enables dual-mode configuration: either dynamic mode toggling (HIGH/LOW logic) or static Smart-CONFIG resistor-based setup for fixed switching frequency, internal/external feedback selection, and output discharge enable/disable-all resolved during startup before soft-start begins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports 12-V, 5-V, 3.3-V rails and multi-cell Li-ion battery inputs without external level-shifting. |
| Output Current | Up to 0.6 A - sufficient for powering microcontrollers, sensors, and interface ICs in low-power embedded systems. |
| Quiescent Current | 4 µA typical - enables >10-year battery life in always-on IoT nodes with 100-µAh coin cells. |
| Output Voltage Accuracy | ±1% over –40°C to +125°C - ensures reliable operation of precision analog circuits and ADC references. |
| Switching Frequency | Selectable 1 MHz or 2.5 MHz - allows trade-off between inductor size (smaller at 2.5 MHz) and EMI filtering complexity. |
| RDS(on) | 250 mΩ (HS) / 85 mΩ (LS) - minimizes conduction loss at full load; enables >90% peak efficiency at 3.3-V/0.6-A output. |
| Package | SOT-5X3 (8-pin, 1.6 mm × 2.1 mm) - ultra-compact footprint compatible with automated SMT assembly and thermal vias to PCB ground plane. |
Pinout & Package
SOT-5X3 (8-pin) package with 0.5-mm pitch and 1.60 mm × 2.10 mm body size (including pins). Exposed thermal pad enhances thermal performance in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB/VSET | Feedback or voltage-set input | Configurable: external resistor divider (FB mode) or GND-referenced resistor (VSET mode) selects 18 fixed outputs from 0.4 V to 5.5 V. |
| PG | Open-drain power-good output | Signals valid output regulation; requires external pull-up; used for rail sequencing in multi-voltage systems. |
| VOS | Output voltage sense | Direct connection to output capacitor positive terminal enables accurate remote sensing and tight load regulation. |
| SW | Switch node | Connects to internal HS/LS FETs; drives external inductor; requires low-inductance layout to minimize EMI and switching losses. |
| GND | Power ground | Primary return path for power and control circuits; must be tied to thermal pad and low-impedance PCB plane. |
| VIN | Input supply | Accepts 3–17 V; requires local 4.7-µF ceramic capacitor placed adjacent to pin to suppress high-frequency ripple. |
| EN | Enable input | Precision threshold (0.9–1.03 V rising); supports RC-delayed startup and programmable UVLO via external divider. |
| MODE/S-CONF | Mode and configuration input | Dual-function: logic-level (PWM/PFM toggle) or resistor-coded (static config for freq, feedback, discharge). |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Internally compensated loop eliminates external compensation components and guarantees stability with low-ESR ceramic capacitors. |
| No bootstrap capacitor required | Integrated charge pump enables high-side gate drive without external boot diode/capacitor-reducing BOM count and layout area. |
| 100% duty cycle operation | Maintains regulation down to VOUT ≈ VIN − 0.3 V, enabling use in low-dropout scenarios like post-regulation of 5-V supplies to 3.3 V. |
| Overcurrent & thermal protection | Auto-recovering shutdown with 170°C trip point and 20°C hysteresis prevents damage during overload or poor heatsinking. |
| Output discharge function | Active discharge via internal 7.5–20 Ω resistor ensures safe, controlled VOUT ramp-down when disabled-critical for FPGA/configurable logic power sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS629210DRLR | 1-A output current, same 3–17-V input, identical SOT-5X3 package and pinout. | Higher current capability suits FPGA core rails or multi-core SoCs where 0.6-A headroom is insufficient. | Select when peak load exceeds 600 mA but layout reuse and firmware compatibility are critical. |
| TPS629203DRLR | 300-mA output current, otherwise identical feature set, package, and pinout. | Lower current rating targets ultra-low-power sensor hubs or wearables where thermal margin and cost optimization dominate. | Choose for sub-300-mA loads to reduce solution size and cost while retaining identical control interface and layout. |
Compared with TPS629206DRLR, TPS629210DRLR offers +400 mA output headroom with no layout change, while TPS629203DRLR reduces cost and thermal footprint for lighter loads-both share identical DCS-Control behavior, MODE/S-CONF configuration, and PG sequencing logic.

FAQ
What is the maximum output current supported by the TPS629206DRLR?
The TPS629206DRLR supports up to 0.6 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Peak current capability is limited by internal current limit thresholds (1.1–1.7 A HS, 0.9–1.5 A LS) and thermal dissipation in the SOT-5X3 package. Derating is required above 85°C ambient.
Does the TPS629206DRLR require an external bootstrap capacitor?
No, the TPS629206DRLR does not require an external bootstrap capacitor. It integrates a charge pump circuit that self-generates the gate drive voltage for the high-side MOSFET, eliminating the need for external boot components and simplifying layout and BOM.
How is output voltage configured on the TPS629206DRLR?
The TPS629206DRLR supports two configuration methods: (1) External feedback via resistive divider connected to FB/VSET pin (0.6 V to 5.5 V), or (2) Internal VSET mode using a single resistor from FB/VSET to GND to select one of 18 fixed outputs (0.4 V to 5.5 V) per Table 8-2 in the datasheet.
What protection features are integrated into the TPS629206DRLR?
The TPS629206DRLR integrates overcurrent protection (HS/LS current limiting), thermal shutdown (170°C trip, 20°C hysteresis), undervoltage lockout (2.85 V rising), and output discharge. All protections are auto-recovering except sustained thermal fault, which requires VIN cycle to reset.
Is the TPS629206DRLR pin-compatible with other devices in its family?
Yes, the TPS629206DRLR is pin-to-pin compatible with the TPS629210DRLR and TPS629203DRLR. All three share identical SOT-5X3 (DRL) package, pin assignment, and functional pin definitions-enabling scalable current selection without PCB redesign.
