Product details
Overview
TPS562210ADDFT 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 power for digital TV and STB applications with <10 µA shutdown current and 1% feedback voltage accuracy.
For engineers reviewing the TPS562210ADDFT datasheet, TPS562210ADDFT pinout, TPS562210ADDFT application, or TPS562210ADDFT equivalent, key selection criteria include input voltage range (4.5–17 V), Eco-mode™ light-load efficiency, power-good signaling, soft-start adjustability, and thermal shutdown at 155°C - all validated for industrial ambient operation (–40°C to 85°C).
Technical Context
The TPS562210ADDFT implements adaptive on-time D-CAP2™ control, eliminating external compensation while supporting ceramic and polymer output capacitors. Its internal one-shot timer sets on-time proportional to VIN and inversely proportional to VOUT, enabling pseudo-fixed-frequency operation across input and load 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, and Advanced Eco-mode™ that transitions into discontinuous conduction mode below ~300 mA to sustain >85% efficiency at light loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A continuous - supports full-rated load without derating at TA = 85°C with proper PCB layout |
| Input Voltage Range | 4.5 V to 17 V - compatible with 5 V, 12 V, and 15 V intermediate bus rails |
| Output Voltage Range | 0.76 V to 7 V - set by external resistor divider; 1.05 V typical for core logic supplies |
| Switching Frequency | 650 kHz - enables compact magnetics and predictable EMI profile |
| Feedback Accuracy | ±1% at 25°C - ensures tight regulation for sensitive SoC and FPGA core voltages |
| Shutdown Current | <10 µA - minimizes system standby power in always-on consumer devices |
| Thermal Shutdown | 155°C with 35°C hysteresis - protects against sustained overload or poor heatsinking |
Pinout & Package
TPS562210ADDFT is housed in an 8-pin SOT-23 package (DDF), measuring 1.60 mm × 2.90 mm, optimized for high-density PCB layouts and thermal performance with RθJA = 106.1°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Power and signal ground reference | Common return path for controller, low-side FET source, and feedback network - must be star-connected to minimize noise coupling |
| SW | Switch node | Connection point between high- and low-side FETs; carries high di/dt switching waveform - requires tight loop area with input/output caps |
| VIN | Main input supply | Drain of high-side FET; accepts 4.5–17 V; requires local 10-µF ceramic decoupling |
| PG | Power good open-drain output | Asserts high after 1.7× soft-start time when VOUT is within ±10%; sinks up to 1 mA for pull-up to 3.3/5 V |
| SS | Soft-start timing control | Capacitor-to-ground sets ramp time; ISS = 6 µA charges CSS to control dVOUT/dt and limit inrush current |
| VFB | Feedback input | Monitors output via resistor divider; 0.765 V threshold; ±0.1 µA input bias enables high-value resistors for low quiescent loss |
| EN | Enable input | Active-high logic control; 1.6 V threshold; internal 450 kΩ pull-down allows direct MCU GPIO drive without external resistor |
| VBST | Bootstrap supply | Supplies gate drive for high-side FET; requires 0.1 µF ceramic capacitor between VBST and SW for charge replenishment |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ Control | Enables stable operation with zero-ESR ceramic capacitors and eliminates 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 - critical for standby power compliance in CE devices |
| Pre-biased Start-up | Allows safe startup into pre-charged output rail without reverse current - essential for hot-swap and multi-rail sequencing systems |
| Power Good Output | Open-drain PG signal provides system-level power sequencing and fault detection - simplifies host processor reset management |
| Integrated FETs | 133-mΩ/80-mΩ RDS(on) pair enables 2-A output in ultra-small SOT-23 - avoids discrete driver + MOSFET layout complexity and losses |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS563210ADDFT | 3-A rated, lower RDS(on) (68 mΩ/39 mΩ), same pinout and control features | Supports higher current loads (e.g., dual-core SoCs); requires larger inductor and output cap | Select when future-proofing for >2 A peak loads or tighter thermal margin is required |
| MP2315DJ-LF-Z | 2-A, 4.5–28 V input, 500 kHz, no PG output, different pinout (8-pin SOIC) | Lacks power-good signaling and pre-biased start-up; requires external compensation | Choose only if PG and Eco-mode are not needed and PCB layout allows SOIC footprint |
Compared with TPS562210ADDFT, TPS563210ADDFT offers higher current capability in identical packaging but increases solution size and cost, while MP2315DJ-LF-Z trades critical features (PG, D-CAP2™, pre-bias) for wider input range and lower unit price - making TPS562210ADDFT optimal for cost-sensitive, feature-complete 2-A consumer power rails.

FAQ
What is the maximum input voltage rating for the TPS562210ADDFT?
The TPS562210ADDFT has an absolute maximum input voltage (VIN) rating of 19 V, but its recommended operating range is strictly 4.5 V to 17 V per the datasheet. Exceeding 17 V during normal operation risks violating thermal and reliability specifications, even if below the 19-V stress limit. The device includes UVLO with 3.75 V nominal turn-on threshold and 0.32 V hysteresis to ensure robust startup behavior within its specified range.
Does the TPS562210ADDFT support pre-biased output startup?
Yes, the TPS562210ADDFT supports pre-biased output startup. When the output capacitor is already charged at enable, the device monitors VFB and delays switching until the internal reference exceeds the present feedback voltage - preventing reverse current flow and ensuring monotonic rise. This behavior is confirmed in Section 7.3.2 of the SLVSDP9 datasheet and is enabled by default with no configuration required.
What is the purpose of the VBST pin on the TPS562210ADDFT?
VBST on the TPS562210ADDFT supplies the gate drive voltage for the integrated high-side N-channel MOSFET. It must be connected via a 0.1 µF ceramic capacitor between VBST and the SW pin to form a bootstrap circuit that replenishes charge during each switching cycle. Without this capacitor, the high-side FET cannot turn on fully, causing failure to regulate or excessive heating. The datasheet specifies VBST voltage must remain between –0.1 V and 6 V relative to SW.
How does the power-good (PG) signal behave during startup and fault conditions for the TPS562210ADDFT?
The TPS562210ADDFT PG pin is an open-drain output that asserts high after 1.7× the soft-start time when VFB reaches ≥90% of the target voltage. It goes low if VFB falls below 85% of target - indicating undervoltage or overload. During hiccup-mode UVP events, PG remains low until regulation is restored. PG does not assert during shutdown or EN deactivation, providing unambiguous system power status for sequencers and supervisors.
Can the TPS562210ADDFT operate with ceramic output capacitors only?
Yes, the TPS562210ADDFT is specifically designed to operate stably with low-ESR ceramic output capacitors - a core benefit of its D-CAP2™ control architecture. The datasheet recommends 20–68 µF total ceramic capacitance (e.g., two 22 µF X5R 0805s) and confirms stability without any external compensation components. Polymer or hybrid capacitors may also be used, but ceramics are preferred for lowest cost, size, and ESL.
