Product details
Overview
TPS562210ADDFR from Texas Instruments is a 2-A synchronous step-down DC/DC converter in an 8-pin SOT-23 (DDF) package, featuring integrated 133-mΩ high-side and 80-mΩ low-side MOSFETs, D-CAP2™ control for fast transient response, 650-kHz fixed switching frequency, and 0.76 V to 7 V adjustable output voltage range. It delivers stable 1.05 V @ 2 A for digital TV power rails with <10 µA shutdown current and 1% feedback accuracy.
For engineers reviewing the TPS562210ADDFR datasheet, TPS562210ADDFR pinout, TPS562210ADDFR application, or TPS562210ADDFR equivalent, key selection criteria include input voltage range (4.5–17 V), Eco-mode™ light-load efficiency, power-good signaling, soft-start adjustability, and compatibility with ceramic output capacitors without external compensation.
Technical Context
The TPS562210ADDFR employs adaptive on-time D-CAP2™ control architecture that eliminates need for external loop compensation while supporting ultra-low-ESR ceramic and polymer output capacitors. Its internal one-shot timer sets on-time proportional to VIN and inversely proportional to VOUT, enabling pseudo-fixed 650-kHz operation across input voltage variations.
It integrates cycle-by-cycle over-current protection via valley-current sensing on the low-side FET, non-latch OVP/UVP with hiccup-mode recovery, thermal shutdown at 155°C, and pre-biased soft-start capability-enabling reliable startup into loaded outputs without reverse current flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A continuous - supports mid-power digital loads like SoC core rails and memory 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 resistor divider; typical use at 1.05 V for DDR memory or 3.3 V for peripherals |
| Switching Frequency | 650 kHz - enables compact magnetics and predictable EMI profile without frequency modulation |
| Feedback Accuracy | ±1% at 25°C - ensures tight regulation for sensitive logic supply domains |
| Shutdown Current | <10 µA - minimizes standby power loss in always-on consumer electronics subsystems |
| Thermal Resistance | RθJA = 106.1°C/W - requires minimal PCB copper area for thermal management in SOT-23 footprint |
Pinout & Package
TPS562210ADDFR uses an 8-pin SOT-23 package (DDF), measuring 1.6 mm × 2.9 mm, optimized for space-constrained applications. The package features exposed pad for enhanced thermal performance and is rated for –40°C to +85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal ground reference | Common return for controller, low-side FET source, and feedback network; must be single-point connected to minimize noise coupling into VFB |
| SW (Pin 2) | Switch node | Connection between high- and low-side MOSFETs; carries high di/dt switching waveform; requires tight layout to SW capacitor and inductor |
| VIN (Pin 3) | Main input supply | Connects to 4.5–17 V input rail; feeds high-side FET drain and internal LDO; requires local 10 µF ceramic decoupling |
| PG (Pin 4) | Power good open-drain output | Asserts high after 1.7× soft-start time when VOUT reaches ±10% of target; used for sequencing and system enable |
| SS (Pin 5) | Soft-start timing control | Charged by internal 6 µA current source; external capacitor to GND sets ramp time (Tss ≈ 0.765 V × CSS/6 µA) |
| VFB (Pin 6) | Feedback input | Senses output voltage via resistor divider; 0.765 V reference enables precise output setting; input bias current <±0.1 µA minimizes divider error |
| EN (Pin 7) | Enable input | Active-high logic control (VENH = 1.6 V min); internal pull-down allows default-off behavior; supports sequencing and standby modes |
| VBST (Pin 8) | Bootstrap supply for high-side gate drive | Requires 0.1 µF ceramic capacitor to SW; generates floating gate voltage for high-side NFET; critical for proper high-side conduction |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ Control Mode | Enables stable operation with zero-ESR ceramic capacitors and no external compensation components - reduces BOM count and design iteration time |
| Advanced Eco-mode™ | Maintains >85% efficiency at 10 mA load by entering discontinuous conduction mode - extends battery life in standby states |
| Pre-Biased Soft Start | Allows safe startup into pre-charged output rails without reverse current - essential for hot-swap and multi-rail sequencing applications |
| Integrated Power Good (PG) | Open-drain PG signal with ±10% threshold and 1.7× soft-start delay - provides deterministic system-level power sequencing and fault indication |
| Cycle-by-Cycle Over-Current Protection | Valley-current sensing on low-side FET with temperature-compensated threshold - prevents MOSFET damage during short-circuit or overload events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS563210ADDFR | 3-A rating, lower RDS(on) (68 mΩ/39 mΩ), same pinout and control architecture | Supports higher current loads (e.g., multi-core SoCs) without redesign; requires larger inductor and output capacitance | Select when output current exceeds 2 A or when lower conduction loss is required at full load |
| MP2307DN-LF-Z | 2-A, 4.5–28 V input, 500 kHz, no PG or SS pins, different pinout (SOIC-8) | Lacks power-good signaling and adjustable soft-start; requires external compensation for ceramic caps | Choose for cost-sensitive, non-sequencing applications where board space allows SOIC-8 and design tolerates reduced feature set |
Compared with TPS562210ADDFR, TPS563210ADDFR offers higher current capacity in identical footprint but increases solution size due to thermal and inductance requirements, while MP2307DN-LF-Z trades integration and precision for lower unit cost and relaxed layout constraints.

FAQ
What is the maximum input voltage rating for the TPS562210ADDFR?
The TPS562210ADDFR has an absolute maximum input voltage rating of 19 V on the VIN pin, but its recommended operating input voltage range is 4.5 V to 17 V. Exceeding 17 V may trigger UVLO or reduce reliability; operation above 19 V risks permanent damage. Always observe derating guidelines per TI SLVSDP9 datasheet Section 6.1.
Does the TPS562210ADDFR support pre-biased output startup?
Yes, the TPS562210ADDFR supports pre-biased soft start: when enabled, it monitors VFB and delays switching until the internal reference exceeds the existing output voltage, preventing reverse current flow into a charged rail. This behavior is confirmed in Section 7.3.2 of the SLVSDP9 datasheet and applies directly to TPS562210ADDFR.
What is the purpose of the VBST pin on the TPS562210ADDFR?
The VBST pin on the TPS562210ADDFR supplies the bootstrap voltage for the high-side MOSFET gate driver. A 0.1 µF ceramic capacitor must be placed between VBST and SW to generate the floating voltage needed to fully enhance the high-side NFET. Incorrect or missing VBST capacitor causes failure to regulate or erratic switching.
How does the TPS562210ADDFR achieve high light-load efficiency?
The TPS562210ADDFR uses Advanced Eco-mode™, which transitions into discontinuous conduction mode at light loads by turning off the low-side FET when inductor current reaches zero. This reduces switching losses and maintains >85% efficiency down to 10 mA, as verified in Figure 19 of the SLVSDP9 datasheet for TPS562210ADDFR.
Can the TPS562210ADDFR be used with only ceramic output capacitors?
Yes, the TPS562210ADDFR is specifically designed for ceramic output capacitors using D-CAP2™ control, which eliminates the need for ESR-based compensation. The datasheet recommends 20–68 µF total ceramic capacitance (e.g., two 22 µF X5R devices) and confirms stability without additional RC networks - validated in Section 8.2.1.2.2 and Table 2.
