Product details
Overview
TPS563207DRLR from Texas Instruments is a 3-A synchronous buck DC-DC converter in SOT563 package, featuring integrated 95-mΩ high-side and 57-mΩ low-side MOSFETs, D-CAP2™ mode control for fast transient response, 4.3–17-V input range, and 0.806–7-V adjustable output voltage. It delivers stable power to compact consumer electronics such as smart speakers and digital set-top boxes.
For engineers reviewing the TPS563207DRLR datasheet, TPS563207DRLR pinout, TPS563207DRLR application, or TPS563207DRLR equivalent, key selection criteria include FCCM operation for light-load ripple control, 580-kHz switching frequency, <3 µA shutdown current, ±2% feedback accuracy at 25°C, and pre-bias soft-start capability for reliable system power-up sequencing.
Technical Context
The TPS563207DRLR implements adaptive on-time D-CAP2™ control with internal ramp compensation, enabling stable regulation using ultra-low-ESR ceramic or polymer output capacitors without external compensation. Its cycle-by-cycle valley-current overcurrent protection monitors low-side FET drain-source voltage with temperature compensation.
It operates in forced continuous conduction mode (FCCM) across load conditions, maintaining fixed ~580-kHz switching frequency with minimal variation over input voltage (4.3–17 V) and output current (0–3 A). Thermal shutdown triggers at 172°C with 37°C hysteresis, and non-latching UVLO activates at 4.3 V (typical) with 0.4-V hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.3 V to 17 V - supports wide-input industrial and consumer rails including 5 V, 9 V, 12 V, and 15 V supplies. |
| Output Current | 3 A continuous - sufficient for powering SoCs, FPGAs, and memory subsystems in compact embedded systems. |
| Switching Frequency | 580 kHz (typical) - balances efficiency, EMI, and component size; varies ±5% over input and load conditions. |
| Feedback Accuracy | ±2% at 25°C - ensures precise output regulation critical for sensitive analog and digital loads. |
| Shutdown Current | <3 µA - enables ultra-low-power standby in battery-backed or energy-conscious applications. |
| Soft-Start Time | 1.2 ms (fixed internal) - prevents inrush current and ensures controlled output ramp-up during power-on. |
| Thermal Shutdown | 172°C threshold with 37°C hysteresis - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
SOT563 (DRL) package: 6-pin, 1.6 mm × 1.6 mm body, 0.5-mm pitch, thermally enhanced exposed pad (GND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input power supply | Accepts 4.3–17 V DC; requires local 10-µF ceramic decoupling and 0.1-µF high-frequency bypass. |
| SW (Pin 2) | Switch node | Connects between internal high-side and low-side MOSFETs; must be routed short/wide to minimize EMI and ringing. |
| GND (Pin 3) | Power and signal ground | Source of low-side FET and controller reference; Kelvin connection required for FB path to avoid noise coupling. |
| BST (Pin 4) | Bootstrap supply | Drives high-side gate; requires 0.1-µF ceramic capacitor between BST and SW pins for proper bootstrap charging. |
| EN (Pin 5) | Enable control | Active-high logic input (1.35–1.6 V threshold); internal 225–900 kΩ pull-down enables default disable if left floating. |
| FB (Pin 6) | Feedback input | Monitors output via resistor divider; 806 mV reference sets VOUT = 0.806 × (1 + RFBT/RRFBB); ±0.1 µA input bias. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control architecture | Enables stable operation with zero-ESR ceramic capacitors and eliminates need for external compensation network. |
| FCCM operation | Maintains constant switching frequency down to light loads, minimizing output voltage ripple and simplifying EMI filtering. |
| Pre-bias soft-start | Allows safe startup into pre-charged output rails-critical for hot-swap and multi-rail sequencing applications. |
| Hiccup-mode OCP | Enters timed restart (18.3 ms hiccup off-time) after overcurrent detection, preventing thermal runaway during sustained faults. |
| Non-latch UVP & TSD | Auto-recovers from undervoltage or overtemperature events once fault condition clears-no manual reset required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS563202DRLR | Uses Eco-mode (discontinuous conduction) instead of FCCM; lower light-load efficiency but higher peak efficiency at mid-load; same pinout and package. | Better suited for battery-powered applications where ultra-low quiescent current dominates design priority. | Select TPS563202DRLR only when light-load efficiency and IQ <10 µA are mandatory; not drop-in for FCCM-critical designs. |
| MP2332HGTL-Z | Monolithic 3-A buck with 500-kHz fixed frequency, 4.5–18-V input, but lacks pre-bias soft-start and D-CAP2™ adaptive control. | Requires external compensation and larger output capacitance; suitable for cost-sensitive, non-sequencing applications. | Choose MP2332HGTL-Z for simpler designs where fixed-frequency predictability outweighs transient performance needs. |
Compared with TPS563207DRLR, TPS563202DRLR trades FCCM stability for Eco-mode efficiency at light loads, while MP2332HGTL-Z offers broader input range but demands more external components and sacrifices startup robustness into pre-biased rails.

FAQ
What is the recommended input capacitor configuration for TPS563207DRLR?
TI recommends a combination of a 10-µF ceramic bulk capacitor and a 0.1-µF high-frequency bypass capacitor placed directly at the VIN and GND pins. The 0.1-µF capacitor must be located adjacent to Pin 1 (VIN) and Pin 3 (GND) to suppress high-frequency switching noise. Voltage rating should exceed the maximum input voltage (≥20 V).
Does TPS563207DRLR support output voltage sequencing with other rails?
Yes, TPS563207DRLR supports controlled sequencing via its EN pin and pre-bias soft-start function. When enabled into a pre-charged output, the device delays switching until its internal reference exceeds the FB voltage, preventing reverse current flow and ensuring monotonic startup-critical for multi-rail SoC power domains.
What is the purpose of the BST pin on TPS563207DRLR, and how must it be connected?
The BST pin supplies gate drive voltage for the internal high-side MOSFET. It must be connected to SW through a 0.1-µF ceramic capacitor (X7R or better). This capacitor charges during low-side conduction and provides the bootstrap voltage needed to fully enhance the high-side FET. Incorrect BST routing causes erratic switching or failure to regulate.
Can TPS563207DRLR operate with ceramic output capacitors only?
Yes, TPS563207DRLR is explicitly optimized for ceramic and specialty polymer capacitors due to its D-CAP2™ control architecture. It requires no external compensation and remains stable with ultra-low-ESR outputs-TI recommends 20–68 µF total capacitance, typically implemented with two parallel 22-µF X5R/X7R MLCCs.
What protection features does TPS563207DRLR include, and are they auto-recovering?
TPS563207DRLR includes hiccup-mode overcurrent protection, non-latching undervoltage lockout (UVLO), and non-latching thermal shutdown (TSD). All three protections automatically recover once the fault condition is removed-no external reset or power cycle is required, enabling robust operation in unattended systems.
