Product details
Overview
TPS563202DRLR from Texas Instruments is a 3-A synchronous buck DC-DC converter in a 6-pin SOT563 package, featuring D-CAP2™ mode control, 4.3–17-V input range, 0.806–7-V adjustable output, and integrated 95-mΩ/57-mΩ FETs. It delivers fast transient response for digital TV power rails and smart speaker core supplies.
For engineers reviewing the TPS563202DRLR datasheet, TPS563202DRLR pinout, TPS563202DRLR application, or TPS563202DRLR equivalent, key selection criteria include ECO-mode light-load efficiency, 580-kHz fixed-frequency operation, cycle-by-cycle overcurrent protection, hiccup-mode fault recovery, and pre-bias soft-start capability.
Technical Context
The TPS563202DRLR implements adaptive on-time D-CAP2™ control with internal ramp compensation, enabling stable regulation with ultra-low-ESR ceramic or polymer output capacitors-no external compensation required. Its valley-current sensing supports precise cycle-by-cycle current limiting and seamless transition between continuous conduction mode (CCM) and pulse-skipping Eco-mode.
Thermal protection includes non-latching thermal shutdown at 172°C with 37°C hysteresis, while undervoltage lockout (UVLO) activates at 4.3 V (with 0.4-V hysteresis) and disables below 3.6 V. The device maintains 2% feedback voltage accuracy across –40°C to 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.3 V to 17 V - Supports wide-input industrial and consumer DC supplies including 5 V, 9 V, 12 V, and 15 V rails. |
| Output Current | 3 A continuous - Delivers full rated load without derating at TJ ≤ 125°C with proper PCB thermal design. |
| Switching Frequency | 580 kHz typical - Enables compact magnetics and predictable EMI profile; varies ±10% with VIN and IOUT. |
| Feedback Accuracy | ±2% at 25°C - Ensures tight output regulation for sensitive SoC cores and memory interfaces. |
| Shutdown Current | <3 µA - Minimizes system standby power in always-on applications like smart speakers and surveillance cameras. |
| Soft-Start Time | 1.2 ms fixed - Prevents inrush current and ensures monotonic VOUT ramp during power-up. |
| Thermal Resistance | RθJA = 137°C/W (standard JEDEC board); RθJB = 22.0°C/W - Requires minimal copper area for thermal management. |
Pinout & Package
TPS563202DRLR uses a 6-pin, 1.6 mm × 1.6 mm SOT563 (DRL) package with exposed thermal pad. Pin 1 is VIN; pins are arranged in single-row configuration with GND at pin 3 and BST at pin 4 for bootstrap capacitor connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply rail | Accepts 4.3–17 V; requires local 10-µF ceramic decoupling and optional 0.1-µF high-frequency bypass. |
| SW (Pin 2) | Switch node | Connects high-side and low-side FETs; must be routed short/wide to minimize EMI and switching losses. |
| GND (Pin 3) | Power and signal ground | Serves as source for low-side FET and reference for FB; Kelvin connection to FB resistor divider required. |
| BST (Pin 4) | Bootstrap supply | Requires 0.1-µF ceramic capacitor to SW; enables high-side gate drive above VIN. |
| EN (Pin 5) | Enable control | Active-high logic input; threshold 1.35–1.6 V; internal pull-down ensures default disable at power-up. |
| FB (Pin 6) | Feedback input | Monitors output via resistor divider; sets VOUT = 0.806 V × (1 + R1/R2); input bias current < ±0.1 µA. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control architecture | Enables stable operation with zero-ESR ceramic capacitors and eliminates need for external compensation network. |
| ECO mode at light load | Reduces switching frequency proportionally to load, maintaining >85% efficiency down to 1 mA output current. |
| Pre-bias soft-start | Allows safe startup into pre-charged output rails without reverse current or overshoot-critical for hot-swap systems. |
| Hiccup-mode overcurrent protection | Enters 2.2-ms fault-on / 18.3-ms restart cycle upon sustained overcurrent, preventing thermal runaway. |
| Non-latch UVP and TSD | Shuts down temporarily on undervoltage or overtemperature, then auto-restarts when conditions normalize. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS563201DRLR | Same package and pinout; lower 2-A rating; identical D-CAP2™ control and Eco-mode features. | Not suitable for 3-A loads; acceptable where peak current remains ≤2 A with margin. | Select when full 3-A capability is unnecessary-reduces cost and thermal overhead. |
| MP2332HGTL-Z | 3-A rating, 4.5–18-V input, but uses current-mode control; no pre-bias soft-start; 500-kHz nominal frequency. | Lacks pre-bias start and Eco-mode; requires external compensation; higher light-load quiescent current (~25 µA). | Choose for cost-sensitive designs where D-CAP2™ advantages are secondary to BOM simplicity. |
Compared with TPS563202DRLR, TPS563201DRLR offers identical functionality at reduced current capacity, while MP2332HGTL-Z trades D-CAP2™ benefits for broader input range and different control architecture-neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum output current capability of the TPS563202DRLR?
The TPS563202DRLR is rated for 3 A continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 12 V, VOUT = 3.3 V). Peak current capability reaches 4.4 A before cycle-by-cycle overcurrent protection engages, ensuring robust handling of short-duration transients without shutdown.
Does the TPS563202DRLR support pre-biased output startup?
Yes, the TPS563202DRLR supports pre-biased soft-start. When the output capacitor is pre-charged, the device delays switching until the internal reference voltage exceeds the FB pin voltage, preventing reverse current flow and output voltage overshoot-critical for hot-swap and multi-rail sequencing applications.
What package type and thermal characteristics does the TPS563202DRLR use?
The TPS563202DRLR uses a 6-pin SOT563 (DRL) package measuring 1.6 mm × 1.6 mm with an exposed thermal pad. Its junction-to-board thermal resistance (RθJB) is 22.0°C/W, and junction-to-ambient (RθJA) is 137.0°C/W on standard JEDEC test board-enabling full 3-A operation with minimal PCB copper area.
How does the D-CAP2™ control mode benefit system design with the TPS563202DRLR?
D-CAP2™ control in the TPS563202DRLR eliminates the need for external compensation components and supports ultra-low-ESR ceramic and polymer output capacitors. This simplifies layout, reduces component count, improves transient response (±5% deviation on 1.5-A load step), and enhances stability across varying output capacitor ESR values.
What protection features are integrated into the TPS563202DRLR?
The TPS563202DRLR integrates cycle-by-cycle overcurrent limit, hiccup-mode fault recovery (2.2-ms on / 18.3-ms off), non-latching thermal shutdown (172°C threshold), non-latching undervoltage lockout (4.3-V enable, 3.6-V disable), and output undervoltage protection. All protections auto-recover without external intervention.
