Product details
Overview
TPS563207SDRLR from Texas Instruments is a 3-A synchronous buck converter in SOT563 (DRL) package, operating from 4.3 V to 17 V input and delivering adjustable output from 0.806 V to 7 V. It employs D-CAP2™ mode control for fast transient response, supports FCCM operation with 580-kHz typical switching frequency, and integrates 95-mΩ high-side and 57-mΩ low-side MOSFETs - used in digital STB, smart speaker, and wired networking power rails.
For engineers reviewing the TPS563207SDRLR datasheet, TPS563207SDRLR pinout, TPS563207SDRLR application, or TPS563207SDRLR equivalent, key selection criteria include its FCCM light-load behavior, 1.5% feedback accuracy at 25°C, pre-bias soft-start capability, hiccup-mode overcurrent protection, and thermal shutdown at 172°C - all critical for compact, high-efficiency 3-A point-of-load designs.
Technical Context
The TPS563207SDRLR implements adaptive on-time D-CAP2™ control, combining internal ramp compensation with pseudo-fixed-frequency operation to enable stable regulation using ultra-low-ESR ceramic or polymer output capacitors - eliminating external compensation networks. Its valley-current-based cycle-by-cycle overcurrent detection monitors low-side FET drain-source voltage with temperature compensation.
FCCM mode ensures continuous conduction across load range, maintaining small output ripple even at light loads. The device integrates bootstrap circuitry requiring a 0.1-µF BST–SW capacitor, and features non-latching UVLO (4.3 V turn-on), thermal shutdown (172°C), and 1.2-ms fixed soft-start - all optimized for space-constrained industrial and consumer DC/DC applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.3 V to 17 V - supports wide-input industrial and consumer supplies including 5 V, 9 V, 12 V, and 15 V rails. |
| Output Voltage Range | 0.806 V to 7 V - programmable via external resistor divider; enables core logic, I/O, and analog rail generation. |
| Max Output Current | 3 A continuous - sufficient for SoC cores, DSPs, and FPGA I/O banks in compact embedded systems. |
| Switching Frequency | 580 kHz typical - balances efficiency, size, and EMI; varies <±5% with input/output conditions per datasheet curves. |
| Feedback Accuracy | ±1.5% at 25°C - ensures tight output regulation critical for voltage-sensitive processors and sensors. |
| Shutdown Current | <3 µA - enables ultra-low-power standby in battery-backed or always-on edge devices. |
| Thermal Shutdown | 172°C with 37°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
| Package | SOT563 (DRL), 1.6 mm × 1.6 mm - 6-pin thermally enhanced surface-mount package for high-density layouts. |
Pinout & Package
SOT563 (DRL) package: 6-pin, 1.6 mm × 1.6 mm body, exposed thermal pad (not electrically connected), rated for –40°C to 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply connection | Accepts 4.3–17 V DC; requires local 10-µF ceramic decoupling and 0.1-µF high-frequency bypass near pin. |
| SW (Pin 2) | Switch node | Connects between integrated high-side and low-side NFETs; must be routed short/wide to minimize EMI and ringing. |
| GND (Pin 3) | Power and signal ground | Common return for controller, low-side FET source, and FB reference; Kelvin connection required for FB path stability. |
| BST (Pin 4) | Bootstrap supply | Drives high-side gate; requires 0.1-µF ceramic capacitor between BST and SW - no series resistance or ferrite. |
| EN (Pin 5) | Enable control | Active-high logic input (1.35–1.6 V threshold); pull-up required for operation; enables system-level power sequencing. |
| FB (Pin 6) | Feedback input | Monitors output via resistor divider; 806 mV reference sets VOUT = 0.806 × (1 + RFBT/RRFBB); sensitive to noise - keep trace short and shielded. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control architecture | Enables stable operation with ceramic/polymer output caps without external compensation - reduces BOM count and layout complexity. |
| FCCM operation mode | Maintains continuous conduction down to zero load, minimizing output voltage ripple and avoiding audible noise in light-load conditions. |
| Pre-bias soft-start | Allows safe startup into pre-charged output rails - prevents reverse current flow and avoids system reset during hot-plug or brownout recovery. |
| Hiccup-mode OCP | Enters 2.2-ms fault-on / 18.3-ms restart cycle on sustained overcurrent - protects MOSFETs and inductor while enabling automatic recovery. |
| Integrated 95-mΩ/57-mΩ FETs | Reduces conduction loss and eliminates external power stage components - achieves >90% peak efficiency at 3 A (e.g., 12 V → 3.3 V). |
| Non-latch UVP & TSD | Shuts down on output undervoltage or die overtemperature, then auto-restarts when condition clears - improves system robustness. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS563202SDRLR | Uses Eco-mode (discontinuous conduction) instead of FCCM; lower light-load IQ (~25 µA vs <3 µA), 2-A rating. | Better light-load efficiency in battery-powered apps; unsuitable where FCCM ripple suppression is required. | Select only if light-load efficiency > FCCM stability; not drop-in due to different control loop behavior and current rating. |
| MP2332HGTL-Z | Monolithic 3-A buck with 500-kHz fixed frequency; 4.5–28 V input; no pre-bias soft-start; 1.2% FB accuracy. | Broader input range suits 24-V industrial systems; lacks D-CAP2™ transient performance and FCCM light-load behavior. | Consider for higher VIN applications where 17-V max is insufficient; verify layout compatibility - different pinout and thermal pad. |
Compared with TPS563207SDRLR, TPS563202SDRLR trades FCCM stability for Eco-mode efficiency at microamp loads, while MP2332HGTL-Z offers wider input range but sacrifices D-CAP2™ transient response and pre-bias capability - making TPS563207SDRLR optimal for compact, fast-transient consumer electronics rails.

FAQ
What is the recommended input capacitor configuration for TPS563207SDRLR?
TI recommends a minimum 10-µF ceramic input capacitor placed as close as possible to the VIN and GND pins, plus a 0.1-µF high-frequency bypass capacitor from Pin 3 (GND) to VIN. This dual-capacitor approach suppresses both bulk and high-frequency noise, ensuring stable operation across the full 4.3–17 V input range and preventing EN false triggering or SW node oscillation in the TPS563207SDRLR.
Does TPS563207SDRLR support output voltage sequencing with other power rails?
Yes, TPS563207SDRLR supports controlled sequencing via its active-high EN pin (Pin 5), which has a precise 1.35–1.6 V enable threshold and 225–900 kΩ internal pull-down resistance. By coordinating EN timing with upstream regulators or GPIOs, designers can implement power-up/down sequences - for example, enabling TPS563207SDRLR only after a 5-V bias rail stabilizes, ensuring proper BST capacitor charging before switching begins.
Can TPS563207SDRLR operate with 100% duty cycle?
No, TPS563207SDRLR cannot operate at 100% duty cycle. Its maximum recommended operating duty cycle is 75%, meaning the minimum valid input voltage is VOUT/0.75. For a 3.3-V output, VIN must remain ≥4.4 V. Below this ratio, regulation fails and the device may enter dropout or undefined behavior - a hard limit enforced by the adaptive on-time control architecture of the TPS563207SDRLR.
What is the purpose of the BST capacitor in TPS563207SDRLR, and what value is required?
The BST capacitor (0.1-µF ceramic, placed between BST and SW pins) supplies gate drive voltage for the integrated high-side MOSFET. It charges through an internal diode during low-side conduction and powers the high-side driver during its on-time. Using the specified 0.1-µF value ensures sufficient charge storage for reliable 580-kHz switching; deviation causes gate underdrive, increased RDS(on), and thermal stress in the TPS563207SDRLR.
How does the TPS563207SDRLR handle startup into a pre-biased output?
TPS563207SDRLR implements true pre-bias soft-start: when EN is asserted, the internal reference ramps only after VFB falls below the 806-mV threshold. This prevents reverse current flow into the pre-charged output capacitor, avoids output voltage overshoot, and eliminates risk of damaging downstream logic. The feature is intrinsic to the TPS563207SDRLR control architecture and requires no external components or configuration.
