Product details
Overview
TPS563200DDCT 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 topology 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 and is deployed in digital TV power supplies requiring compact, efficient point-of-load regulation.
For engineers reviewing the TPS563200DDCT datasheet, TPS563200DDCT pinout, TPS563200DDCT application, or TPS563200DDCT equivalent, key selection considerations include its Eco-mode light-load efficiency, 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 TPS563200DDCT implements adaptive on-time D-CAP2™ control, where on-time is inversely proportional to VIN and proportional to VOUT to maintain quasi-fixed 650 kHz operation across input and load variations. Its internal ramp compensates for zero-output-ripple conditions, enabling stable regulation with ultra-low-ESR ceramic capacitors.
It integrates cycle-by-cycle valley-current sensing via low-side FET RDS(on) voltage monitoring, temperature-compensated for accuracy, and supports non-latch OVP (125% × VFBTH), hiccup-mode UVP (65% × VFBTH), and thermal shutdown at 155°C. Soft-start is fixed at 1 ms and includes pre-biased output support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 3 A maximum continuous - supports mid-power SoC core rails and FPGA I/O supplies |
| Input voltage range | 4.5 V to 17 V - compatible with 5 V, 12 V, and 15 V intermediate bus architectures |
| Output voltage range | 0.76 V to 7 V - programmable via external resistor divider for DDR, CPU, and peripheral rails |

Pinout & Package
TPS563200DDCT uses a 6-pin SOT-23 package (DDC variant), measuring 1.6 mm × 2.9 mm, optimized for space-constrained PCB layouts in consumer and networking applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal ground reference | Return path for low-side FET source and controller circuitry; requires single-point VFB grounding for stability |
| SW (Pin 2) | Power switch node | Connection between high- and low-side MOSFETs; high di/dt node requiring minimized loop area and direct capacitor coupling to VBST |
| VIN (Pin 3) | Main input supply | Drain of high-side FET; accepts 4.5–17 V; must be decoupled with low-ESR ceramic capacitor near package |
| VFB (Pin 4) | Feedback input | Monitors output voltage via resistor divider; threshold is 765 mV typical; ±1% accuracy enables precise regulation |
| EN (Pin 5) | Enable control | Active-high logic input; internal pull-down; requires ≥1.6 V to enable; supports sequencing and power-down control |
| VBST (Pin 6) | Bootstrap supply | Provides gate drive voltage for high-side FET; requires 0.1 µF ceramic capacitor between VBST and SW |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Eco-mode pulse-skip | Maintains >85% efficiency at 10 mA load by reducing switching frequency proportionally to output current |
| Pre-biased soft-start | Enables safe startup into existing output voltage without reverse current flow or overshoot |
| Cycle-by-cycle overcurrent limit | Valley-current detection with temperature compensation ensures accurate 3.5–5.3 A current limiting across temperature |
| Hiccup-mode undervoltage protection | Shuts down for 7 ms after 14 µs UVP detection, then auto-retries - prevents latch-up during brownout |
| Non-latch OVP and UVLO | OVP triggers at 125% × VFBTH; UVLO releases at 3.75 V with 0.32 V hysteresis - ensures robust fault recovery |

FAQ
What is the maximum output current rating of the TPS563200DDCT?
The TPS563200DDCT is rated for 3 A continuous output current under recommended operating conditions (TA = –40°C to 85°C, proper PCB layout, and adequate thermal dissipation). Its cycle-by-cycle overcurrent limit is specified from 3.5 A to 5.3 A depending on output voltage and inductor value, ensuring reliable operation under transient overload conditions without latch-up.
Does the TPS563200DDCT support pre-biased output startup?
Yes, the TPS563200DDCT supports pre-biased soft-start. When the EN pin is asserted high and the VFB pin already senses a voltage above the internal reference (765 mV), the device delays switching until the internal soft-start ramp exceeds the present VFB level - preventing reverse current flow and output voltage undershoot during hot-insertion or multi-rail sequencing.
What package type and dimensions does the TPS563200DDCT use?
The TPS563200DDCT uses the DDC package: a 6-pin SOT-23 variant measuring 1.6 mm × 2.9 mm with 0.95 mm height. This compact outline enables high-density placement in consumer electronics such as STBs and Blu-ray players, and it is fully compatible with standard SOT-23 reflow profiles and automated assembly processes.
How does the D-CAP2™ control topology improve transient response in the TPS563200DDCT?
The D-CAP2™ control in the TPS563200DDCT eliminates external compensation by embedding an internal ramp that simulates output ripple, enabling direct response to load steps without phase-margin constraints. This architecture achieves sub-10-µs recovery time from 1-A load transients and supports ultra-low-ESR ceramic capacitors - reducing output capacitance requirements by up to 40% versus traditional voltage-mode controllers.
What protection features are integrated into the TPS563200DDCT?
The TPS563200DDCT integrates cycle-by-cycle overcurrent limit, hiccup-mode undervoltage protection (UVP), non-latch overvoltage protection (OVP), thermal shutdown at 155°C, and undervoltage lockout (UVLO) with 3.75-V turn-on threshold. These protections operate independently and recover automatically - no external circuitry is needed to ensure safe operation during fault conditions like shorted outputs or input brownouts.
