Product details
Overview
TPS562202SDRLR from Texas Instruments is a 2-A synchronous buck DC-DC converter in SOT563 (DRL) package, featuring D-CAP2™ mode control, 4.3–17-V input range, 0.804–7-V adjustable output, and ECO mode for light-load efficiency. It integrates 140-mΩ high-side and 84-mΩ low-side MOSFETs and delivers fast transient response in TV power supplies, smart speakers, and wired networking equipment.
For engineers reviewing the TPS562202SDRLR datasheet, TPS562202SDRLR pinout, TPS562202SDRLR application, or TPS562202SDRLR equivalent, key selection criteria include its 580-kHz fixed switching frequency, 1.5% feedback voltage accuracy at 25°C, cycle-by-cycle overcurrent protection, hiccup-mode fault recovery, and support for pre-bias start-up in space-constrained embedded power rails.
Technical Context
The TPS562202SDRLR implements adaptive on-time D-CAP2™ control with internal ramp compensation, enabling stable operation with ultra-low-ESR ceramic or polymer output capacitors without external compensation. Its quasi-fixed 580-kHz switching frequency varies <±10% across input voltage (4.3–17 V) and load (0.001–2 A), maintaining predictable timing behavior in dynamic systems.
ECO mode enables discontinuous conduction at light loads by detecting zero inductor current and extending off-time proportionally-reducing switching losses while preserving regulation. Protection architecture includes non-latching UVLO (4.3 V turn-on), thermal shutdown (160°C trip, 135°C recovery), and valley-current-based cycle-by-cycle OCL with hiccup restart (2.2-ms on, 18-ms off).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.3 V to 17 V - supports wide-input industrial and consumer DC rails including 5 V, 9 V, 12 V, and 15 V bus systems. |
| Output Current | 2 A continuous - sufficient for powering SoCs, FPGAs, and DSPs in compact audio/video and networking devices. |
| Switching Frequency | 580 kHz - enables use of small 2.2–4.7 µH inductors and reduces EMI filtering burden in high-density PCB layouts. |
| Feedback Accuracy | ±1.5% at 25°C - ensures tight output regulation for sensitive analog and digital loads without trimming. |
| Quiescent Current | 520 µA typical - minimizes standby power loss in always-on applications like smart speaker wake-on-voice circuits. |
| Shutdown Current | <3 µA - enables ultra-low-power system-level sleep modes without external load switches. |
| Thermal Resistance | RθJA = 141 °C/W (standard board), RθJA_effective = 75 °C/W (TI EVM) - defines derating curves for 2-A operation in ambient up to 85°C. |
Pinout & Package
SOT563 (DRL) package: 6-pin, 1.6 mm × 1.6 mm body size, 0.5-mm pitch, thermally enhanced exposed pad (GND-connected). Designed for high-density layout with minimal footprint and efficient heat dissipation through bottom-side copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply rail | Accepts 4.3–17 V DC; requires local 10-µF ceramic + 0.1-µF high-frequency decoupling placed adjacent to pin. |
| SW (Pin 2) | Switch node | Connects between integrated high- and low-side NFETs; carries high dv/dt switching waveform-must be short, wide, and isolated from sensitive traces. |
| GND (Pin 3) | Power and signal ground | Common return for low-side FET source and controller circuitry; FB trace must connect to this pin at single-point Kelvin location. |
| BST (Pin 4) | Bootstrap supply | Drives high-side gate; requires 0.1-µF ceramic capacitor between BST and SW pins-critical for proper high-side turn-on. |
| EN (Pin 5) | Enable control | Active-high logic input (1.35–1.6 V threshold); internal 400-kΩ pull-down allows direct connection to microcontroller GPIO or open-drain sequencer. |
| FB (Pin 6) | Feedback input | Monitors output via resistor divider; 804-mV reference enables precise output setting (e.g., 1.05 V using 3 kΩ/10 kΩ divider). |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control mode | Enables stable regulation with ceramic/polymer output capacitors without external compensation-reduces BOM count and layout complexity. |
| ECO mode operation | Maintains >80% efficiency at 1 mA load by entering discontinuous conduction and scaling switching frequency inversely with output current. |
| Pre-bias start-up support | Allows safe startup into pre-charged output rails-prevents reverse current flow and avoids output voltage overshoot during hot-plug events. |
| Fixed 1.2-ms soft start | Controls inrush current and prevents output overshoot during power-up; eliminates need for external soft-start timing components. |
| Hiccup-mode OCP | Shuts down for 18 ms after overcurrent detection, then auto-restarts-protects against sustained shorts while avoiding latch-off in transient faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562207SDRLR | Uses FCCM (forced continuous conduction mode) instead of ECO mode; higher light-load quiescent current (1.2 mA vs 0.52 mA). | Better suited for applications requiring constant switching frequency under all loads (e.g., EMI-sensitive RF sections). | Select TPS562207SDRLR only when deterministic frequency behavior outweighs light-load efficiency requirements. |
| MP2315GJ-Z | 3-A rating, 2.5-MHz switching, different pinout (SOT563 but non-pin-compatible), no pre-bias start-up support. | Targets higher-current, smaller-footprint designs where 2.5-MHz operation enables sub-1-µH inductors. | Choose MP2315GJ-Z when output current exceeds 2 A or board space demands >1-MHz operation-requires PCB redesign. |
Compared with TPS562207SDRLR and MP2315GJ-Z, the TPS562202SDRLR uniquely balances 2-A capability, ECO-mode efficiency below 10 mA, and seamless pre-bias start-up-making it optimal for cost-sensitive, thermally constrained consumer electronics where standby power and reliability are critical.

FAQ
What is the maximum output voltage supported by the TPS562202SDRLR?
The TPS562202SDRLR supports an output voltage range of 0.804 V to 7 V, set by an external resistor divider connected to the FB pin. The 0.804-V internal reference enables precise low-voltage regulation-for example, a 1.05-V output uses a 3-kΩ top resistor and 10-kΩ bottom resistor per TI's recommended design procedure.
Does the TPS562202SDRLR support pre-bias start-up, and how does it behave?
Yes, the TPS562202SDRLR supports pre-bias start-up: when the output capacitor is already charged, the device delays switching until its internal reference voltage ramps above the existing FB voltage. This prevents reverse current flow and ensures monotonic, overshoot-free startup-critical for hot-swap and multi-rail sequencing applications.
What is the purpose of the BST pin on the TPS562202SDRLR, and what capacitor value is required?
The BST pin on the TPS562202SDRLR supplies the gate drive voltage for the integrated high-side MOSFET. A 0.1-µF ceramic capacitor must be placed between BST and SW pins to provide charge storage for bootstrap operation. TI specifies X7R or better dielectric with 10-V rating to ensure reliable high-side turn-on across temperature and input voltage ranges.
How does ECO mode improve efficiency at light loads in the TPS562202SDRLR?
In ECO mode, the TPS562202SDRLR detects zero inductor current and enters discontinuous conduction, extending off-time proportionally to load reduction. This scales switching frequency downward-e.g., from 580 kHz at full load to ~50 kHz at 1 mA-cutting switching losses while maintaining regulation, achieving >85% efficiency at 10 mA output current.
What protection features are integrated into the TPS562202SDRLR?
The TPS562202SDRLR integrates cycle-by-cycle overcurrent limiting, hiccup-mode fault recovery (2.2-ms shutdown, 18-ms retry), non-latching undervoltage lockout (UVLO with 4.3-V turn-on), and thermal shutdown (160°C trip with 25°C hysteresis). All protections are fully autonomous-no external components required for basic fault coverage.
