Product details
Overview
TPS563200DDCR from Texas Instruments is a 3-A synchronous step-down (buck) DC-DC converter in a 6-pin SOT-23 package, featuring integrated 68-mΩ high-side and 39-mΩ low-side MOSFETs, D-CAP2™ control for fast transient response, 650 kHz switching frequency, and 1% feedback voltage accuracy at 25°C. It delivers regulated output voltages from 0.76 V to 7 V across 4.5–17 V input range for compact power rails in consumer electronics.
For engineers reviewing the TPS563200DDCR datasheet, TPS563200DDCR pinout, TPS563200DDCR application, or TPS563200DDCR equivalent, key selection criteria include its Eco-mode efficiency at light loads, pre-biased soft-start capability, cycle-by-cycle overcurrent protection, hiccup-mode undervoltage protection, and compatibility with low-ESR ceramic and polymer output capacitors without external compensation.
Technical Context
The TPS563200DDCR employs D-CAP2™ adaptive on-time control, combining internal ramp generation with valley-current sensing to achieve stable regulation with zero-ripple ceramic capacitors and eliminate external compensation networks. Its control loop dynamically adjusts on-time inversely with VIN and proportionally with VOUT to maintain quasi-fixed 650 kHz operation across input and load variations.
It integrates cycle-by-cycle overcurrent limiting via temperature-compensated low-side FET RDS(on) sensing, non-latch OVP (125% × VFB), hiccup-mode UVP (65% × VFB), and thermal shutdown at 155°C. Advanced Eco-mode enables pulse-skipping below light-load thresholds while maintaining <10 µA shutdown current and fixed 1-ms soft-start.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3 A maximum continuous - supports compact point-of-load regulation for SoC cores and memory rails. |
| Input Voltage Range | 4.5 V to 17 V - compatible with 5 V, 12 V, and wide-input industrial/commercial supplies. |
| Output Voltage Range | 0.76 V to 7 V - programmable via external resistor divider for DDR, FPGA, and processor I/O rails. |
| Switching Frequency | 650 kHz nominal - enables small external inductors (e.g., 1.5–2.2 µH) and reduces EMI filtering burden. |
| Feedback Accuracy | ±1% at 25°C - ensures tight output regulation critical for low-voltage digital logic and analog subsystems. |
| Shutdown Current | <10 µA - minimizes system standby power in always-on consumer devices. |
| Control Topology | D-CAP2™ - provides inherent stability with ceramic/polymer capacitors and eliminates compensation components. |
Pinout & Package
TPS563200DDCR uses a 6-pin SOT-23 package (DDC, 1.6 mm × 2.9 mm), optimized for space-constrained PCB layouts and thermal performance with 13.6°C/W junction-to-board resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal ground reference | Common return path for low-side FET source and controller circuitry; requires single-point VFB grounding for accuracy. |
| SW (Pin 2) | Switch node | Connection between high- and low-side FETs; carries high di/dt switching current - must be minimized in layout. |
| VIN (Pin 3) | Main input supply | Connects to bulk input capacitor; powers high-side gate driver and internal LDO - decoupling near pin is critical. |
| VFB (Pin 4) | Feedback input | Senses output voltage via resistor divider; internal 0.76 V reference enables precise output programming. |
| EN (Pin 5) | Enable control | Active-high logic input (1.6 V threshold); allows system-level power sequencing and standby mode activation. |
| VBST (Pin 6) | Bootstrap supply | Drives high-side FET gate; requires 0.1 µF capacitor between VBST and SW to sustain gate voltage during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control topology | Enables stable operation with ultra-low-ESR ceramic capacitors and eliminates external compensation components. |
| Advanced Eco-mode | Maintains >85% efficiency at 10 mA load by skipping pulses - ideal for always-on standby circuits. |
| Pre-biased soft-start | Allows safe startup into pre-charged outputs without reverse current flow or output overshoot. |
| Cycle-by-cycle overcurrent limit | Monitors low-side FET VDS for accurate current sensing - protects against short-circuit and overload events. |
| Hiccup-mode undervoltage protection | Shuts down and auto-restarts after 12 ms upon VFB falling below 65% of target - prevents latch-up during brownout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562200DDCR | 2-A rated; higher RDS(on) (122 mΩ HS / 72 mΩ LS); identical pinout and control features | Suitable for lower-current rails (e.g., auxiliary I/O, sensors) where 3-A headroom is unnecessary | Select when output current ≤2 A and cost sensitivity outweighs margin requirements |
| TPS563252RJER | 3-A rated; 1.5-MHz switching; smaller 1.2-mm × 1.6-mm WSON package; improved light-load efficiency | Better suited for ultra-compact, high-density designs requiring faster transient response and reduced inductor size | Choose for next-gen designs prioritizing board area reduction and higher-frequency operation over legacy SOT-23 compatibility |
Compared with TPS563200DDCR, TPS562200DDCR offers lower current capacity but identical integration and footprint for cost-sensitive 2-A use cases, while TPS563252RJER trades SOT-23 familiarity for higher frequency, smaller size, and enhanced efficiency - making it optimal for space-constrained, high-performance applications.

FAQ
What is the maximum continuous output current of the TPS563200DDCR?
The TPS563200DDCR supports up to 3 A of continuous output current under recommended operating conditions (TA = –40°C to 85°C, proper PCB layout and thermal management). This rating is validated with the integrated 68-mΩ high-side and 39-mΩ low-side MOSFETs, and assumes adequate copper area and airflow per TI's thermal guidelines in the datasheet.
Does the TPS563200DDCR require external compensation components?
No, the TPS563200DDCR does not require external compensation components. Its D-CAP2™ control topology uses internal ramp generation and adaptive on-time modulation to ensure stability with low-ESR ceramic and polymer output capacitors - eliminating the need for traditional Type II or III compensation networks.
Can the TPS563200DDCR start up into a pre-biased output?
Yes, the TPS563200DDCR supports pre-biased soft-start. When the EN pin is asserted high and the output voltage is already present, the device delays switching until its internal reference voltage exceeds the sensed VFB level - preventing reverse current flow and ensuring monotonic, overshoot-free startup.
What protections are built into the TPS563200DDCR?
The TPS563200DDCR integrates cycle-by-cycle overcurrent limiting, non-latch overvoltage protection (125% × VFB), hiccup-mode undervoltage protection (65% × VFB), thermal shutdown at 155°C, and undervoltage lockout (UVLO) with 3.75 V threshold. All protections are fully autonomous and require no external circuitry.
What is the typical switching frequency of the TPS563200DDCR?
The TPS563200DDCR operates at a nominal switching frequency of 650 kHz under typical conditions (VIN = 12 V, VOUT = 1.05 V). Frequency varies slightly with input voltage and load due to its adaptive on-time D-CAP2™ architecture, remaining within ±10% across the full operating range.
