Product details
Overview
TPS563210ADDFR from Texas Instruments is a 3-A synchronous step-down DC/DC converter in an 8-pin SOT-23 (DDF) package, featuring integrated 68-mΩ high-side and 39-mΩ low-side MOSFETs, D-CAP2™ control for fast transient response, 650-kHz fixed switching frequency, and 0.76–7-V adjustable output voltage. It delivers stable power to core logic rails in compact consumer electronics.
For engineers reviewing the TPS563210ADDFR datasheet, TPS563210ADDFR pinout, TPS563210ADDFR application, or TPS563210ADDFR equivalent, key selection criteria include its 4.5–17-V input range, Advanced Eco-mode™ for light-load efficiency, 1% VFB accuracy, power-good (PG) output, and pre-biased startup capability.
Technical Context
The TPS563210ADDFR implements adaptive on-time D-CAP2™ control with internal compensation-enabling stable operation with ceramic or polymer output capacitors without external loop components. Its valley-current over-current protection uses temperature-compensated low-side FET RDS(on) sensing and supports hiccup-mode UVP recovery.
Advanced Eco-mode™ dynamically transitions between continuous and discontinuous conduction modes to maintain >85% efficiency at 10-mA load. The device integrates soft-start via external capacitor on SS pin, power-good monitoring with ±10% window, and non-latching OVP/UVP/TSD protections-all operating across –40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 3 A continuous; supports peak loads up to 5.3 A before hiccup current limiting engages |
| 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; set by external resistor divider with 1% feedback reference accuracy at 25°C |
| Switching frequency | 650 kHz nominal; pseudo-fixed frequency maintained via adaptive on-time control |
| Efficiency | Up to 95% at 1.05 V/2 A (VIN = 12 V); >85% at 10 mA due to Advanced Eco-mode™ |
| Shutdown current | <10 µA; enables ultra-low-power system standby states |
| Thermal protection | Non-latch thermal shutdown at 155°C with 35°C hysteresis; junction-to-board RθJB = 14.6°C/W |
Pinout & Package
TPS563210ADDFR is housed in an 8-pin SOT-23 package (DDF), measuring 1.6 mm × 2.9 mm, optimized for high-density PCB layouts and thermal performance via exposed pad (GND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Power and signal ground | Common return for controller, low-side FET source, and feedback network; must be single-point connected to VFB for noise immunity |
| SW | Switch node | Connection point between high- and low-side FETs; requires tight layout to minimize EMI and ringing |
| 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% of target; sinks ≥1 mA |
| SS | Soft-start timing control | Charged by 6-µA internal current; external capacitor sets ramp time (TSS ≈ 0.765 V × CSS/6 µA) |
| VFB | Feedback input | Monitors output via resistor divider; 0.765-V reference with ±15 mV tolerance over full temperature range |
| EN | Enable input | Active-high logic control (VENH = 1.6 V min); internal 450-kΩ pull-down enables default disable |
| VBST | Bootstrap supply | Provides gate drive for high-side FET; requires 0.1-µF ceramic capacitor to SW for charge replenishment |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control mode | Enables stable regulation with zero-ESR ceramic capacitors and eliminates need for external compensation network |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562210ADDFR | 2-A rated version with higher RDS(on) (133 mΩ/80 mΩ); identical pinout, control architecture, and feature set | Suitable for ≤2-A loads; lower thermal stress at same output voltage but cannot sustain 3-A continuous | Select when output current requirement is ≤2 A and cost optimization is prioritized over headroom |
| MP2332HGTL-Z | 3-A monolithic buck with 500-kHz switching, 4.5–28-V input, but lacks PG output and pre-bias startup | Requires external power-good circuitry and careful sequencing design for multi-rail systems | Choose when wider input range (up to 28 V) is needed and PG functionality is implemented elsewhere |
Compared with TPS562210ADDFR, the TPS563210ADDFR delivers 50% higher continuous current in the same footprint, while MP2332HGTL-Z trades PG and pre-bias features for extended input voltage range-making TPS563210ADDFR optimal for space-constrained, multi-rail consumer applications demanding robust power sequencing.

FAQ
What is the maximum continuous output current supported by the TPS563210ADDFR?
The TPS563210ADDFR supports 3 A continuous output current under recommended operating conditions (TA = –40°C to +85°C, proper PCB thermal design). Its current limit threshold is 3.5–4.2 A (typical), with hiccup-mode protection engaging above 5.3 A to prevent thermal runaway. Derating applies above 60°C ambient.
Does the TPS563210ADDFR support startup into a pre-biased output voltage?
Yes, the TPS563210ADDFR supports pre-biased startup: when enabled, it monitors VFB and delays switching until the internal reference exceeds the existing output voltage, preventing reverse current flow and ensuring monotonic ramp-up. This behavior is confirmed in Section 7.3.2 of the SLVSDP9 datasheet.
What is the purpose of the VBST pin on the TPS563210ADDFR, and what capacitor value is required?
The VBST pin supplies gate drive voltage for the high-side MOSFET. A 0.1-µF ceramic capacitor must be placed between VBST and SW pins to provide charge for the bootstrap circuit during each switching cycle. TI specifies X7R or better dielectric with 10-V rating; placement must be adjacent to the IC with minimal trace length.
How does the D-CAP2™ control architecture in the TPS563210ADDFR improve transient response compared to standard voltage-mode control?
D-CAP2™ uses adaptive on-time control with internal ramp injection to emulate output ripple, eliminating dependence on capacitor ESR for loop stability. This enables direct response to load steps within 5 µs-significantly faster than voltage-mode controllers requiring external compensation-and supports ultra-low-ESR ceramic capacitors without phase-margin trade-offs.
Can the TPS563210ADDFR be used with only ceramic output capacitors, and what is the minimum recommended value?
Yes, the TPS563210ADDFR is specifically designed for ceramic output capacitors. TI recommends 20–68 µF total capacitance (e.g., two parallel 22-µF X5R devices) with ≤5-mΩ ESR. Lower values risk instability; the D-CAP2™ architecture ensures stability down to 10 µF with careful layout, but 20 µF is the validated minimum for full load and temperature range.
