Product details
Overview
TPS562201DDCT from Texas Instruments is a 2A synchronous step-down DC/DC converter in SOT-23-6 (DDC) package, featuring D-CAP2™ control, 4.5V–17V input range, 0.76V–7V adjustable output, and pulse-skip Eco-mode for high light-load efficiency. It integrates 140mΩ high-side and 84mΩ low-side MOSFETs and delivers stable 1.05V/2A power for digital TV and STB applications.
For engineers reviewing the TPS562201DDCT datasheet, TPS562201DDCT pinout, TPS562201DDCT application, or TPS562201DDCT equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative parts with functional distinctions, and supply-chain support for production deployment.
Technical Context
The TPS562201DDCT employs adaptive on-time D-CAP2™ control to achieve fast transient response without external compensation-enabling stable operation with ultra-low-ESR ceramic or polymer output capacitors. Its valley-current-based cycle-by-cycle overcurrent protection triggers hiccup-mode shutdown at ≥2.4A typical current limit.
Operating in Eco-mode below light-load thresholds, it reduces switching frequency proportionally to load current while maintaining 2% VFB accuracy (25°C) and fixed 1.0ms soft-start. Input UVLO activates at 3.8V (wake-up) with 0.4V hysteresis, and thermal shutdown engages at 160°C with 25°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 17V - supports wide-input industrial and consumer rails including 5V, 9V, 12V, and 15V supplies without derating. |
| Output Current | 2A continuous - delivers full rated current at 1.05V–3.3V outputs with proper thermal layout on 2-layer PCB (RθJB = 16.3°C/W). |
| Switching Frequency | 580kHz nominal - enables compact magnetics (e.g., 2.2µH inductor) and balances EMI vs. efficiency in space-constrained designs. |
| VFB Accuracy | ±2% at 25°C - ensures tight output regulation across load/line variations; critical for powering sensitive SoCs and FPGAs. |
| Shutdown Current | <20µA - enables ultra-low-power standby in always-on systems such as surveillance cameras and set-top boxes. |
| Thermal Protection | Non-latch 160°C shutdown with 25°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Control Scheme | D-CAP2™ adaptive on-time - eliminates need for external compensation, simplifies design, and maintains stability with zero-ESR ceramic caps. |
Pinout & Package
SOT-23-6 (DDC) package, 1.6mm × 2.9mm footprint, thermally enhanced with exposed pad (not electrically connected). Designed for reflow-compatible assembly and high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal ground reference | Return path for low-side FET and controller; must be star-connected to VFB ground to avoid regulation error. |
| SW (Pin 2) | Switch node | Connection between high- and low-side MOSFETs; routes high dv/dt switching waveform to external inductor and bootstrap capacitor. |
| VIN (Pin 3) | Main input supply | Accepts 4.5V–17V; requires local 10µF ceramic decoupling and optional 0.1µF HF bypass to GND. |
| VFB (Pin 4) | Feedback input | Monitors output via resistor divider; 0.768V internal reference enables precise output setting (e.g., 1.05V with 3.74kΩ/10kΩ). |
| EN (Pin 5) | Enable control | Active-high logic input; 1.6V threshold allows direct MCU GPIO control; internal 600–2400kΩ pulldown enables default-off behavior. |
| VBST (Pin 6) | Bootstrap supply | Drives high-side gate; requires 0.1µF ceramic capacitor between VBST and SW to sustain gate voltage during high-side conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Pulse-skip Eco-mode | Maintains >85% efficiency at 10mA load by reducing switching frequency-ideal for standby power in digital TVs and STBs. |
| Start-up from prebiased output | Enables hot-swap and rail sequencing without output voltage overshoot or reverse current flow. |
| Hiccup-mode OCP | Enters 10ms restart cycle after overcurrent detection-protects downstream circuitry while allowing automatic recovery. |
| Fixed 1.0ms soft-start | Prevents inrush current and output overshoot during power-up; eliminates need for external timing components. |
| D-CAP2™ control | Supports ceramic output caps down to 20µF total with no external compensation-reduces BOM count and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562208DDCT | Continuous conduction mode (CCM) only; higher quiescent current (350–500µA vs. 120–200µA); identical pinout and package. | Better for constant-load applications requiring lowest output ripple; less suitable for battery-backed or always-on systems. | Select TPS562208DDCT when strict CCM operation is required for EMI filtering or noise-sensitive analog circuits. |
| MP2307DN-LF-Z | 3A rated, 4.5–23V input, 500kHz fixed frequency, no Eco-mode; SOIC-8 package (larger footprint, better thermal performance). | Higher current headroom and wider input range; lacks prebias start-up and D-CAP2™ transient response. | Choose MP2307DN-LF-Z when 3A peak load capability or 23V max input is mandatory, and board space permits SOIC-8. |
Compared with TPS562208DDCT, the TPS562201DDCT trades fixed-frequency predictability for superior light-load efficiency; versus MP2307DN-LF-Z, it offers smaller size and faster transient response but lower current rating and narrower input range.

FAQ
What is the maximum output current capability of the TPS562201DDCT?
The TPS562201DDCT is rated for 2A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB layout). Its cycle-by-cycle overcurrent limit triggers at 2.4A (typical), and thermal shutdown activates at 160°C junction temperature to protect against sustained overload. Full 2A delivery requires adequate copper area and airflow per the 16.3°C/W junction-to-board thermal metric.
Does the TPS562201DDCT support start-up into a prebiased output voltage?
Yes, the TPS562201DDCT supports start-up from a prebiased output. When the EN pin is asserted high while VOUT is already present, the device delays switching until the internal soft-start reference exceeds the feedback voltage (VFB), preventing reverse current flow and output voltage overshoot. This feature is explicitly documented in Section 6.3.3 of the datasheet and validated across –40°C to 125°C.
What is the purpose of the VBST pin on the TPS562201DDCT?
VBST (Pin 6) supplies the gate drive voltage for the integrated high-side MOSFET. It must be connected to SW through a 0.1µF ceramic capacitor to form a charge pump that elevates the gate voltage above VIN during high-side conduction. Without this capacitor, the high-side FET cannot turn on fully, causing excessive conduction loss, thermal stress, and potential failure-TI mandates this capacitor in all valid layouts.
How does Eco-mode operation improve efficiency in the TPS562201DDCT?
Eco-mode in the TPS562201DDCT reduces switching frequency proportionally to load current below the discontinuous conduction threshold, minimizing switching losses during light-load conditions. At 10mA output, efficiency exceeds 85%-a 25–30 percentage-point gain over forced CCM operation-making it ideal for standby power in digital TVs and set-top boxes where low-idle consumption is critical.
Can the TPS562201DDCT be used with ceramic output capacitors only?
Yes, the TPS562201DDCT is specifically designed for use with low-ESR ceramic output capacitors (20µF–68µF total) thanks to its D-CAP2™ control architecture, which embeds internal compensation and eliminates the need for external RC networks. TI validates stability with X5R/X7R ceramics and specifies minimum capacitance values per output voltage in Table 7-2 of the datasheet.
