Product details
Overview
TPS560200DBVT from Texas Instruments is a 4.5-V to 17-V input, 500-mA synchronous step-down DC/DC converter with integrated high- and low-side MOSFETs (0.95 Ω / 0.33 Ω), D-CAP2™ control architecture, 600-kHz switching frequency, and 0.8-V ±1.3% reference voltage. It delivers regulated output voltages from 0.8 V to 6.5 V in a compact 5-pin SOT-23 package and is used in power rails for set-top boxes, modems, and DSL equipment.
For engineers reviewing the TPS560200DBVT datasheet, TPS560200DBVT pinout, TPS560200DBVT application, or TPS560200DBVT equivalent, key selection considerations include light-load efficiency via Advanced Eco-Mode™, no-external-compensation D-CAP2™ operation, safe start-up into prebiased outputs, thermal shutdown at 170°C, and compatibility with ceramic and polymer output capacitors.
Technical Context
The TPS560200DBVT implements adaptive on-time D-CAP2™ control, combining constant on-time operation with internal compensation to achieve fast transient response without external components. Its proprietary circuit supports both ultra-low-ESR ceramic and low-ESR polymer capacitors (e.g., POSCAP/SP-CAP) by emulating ripple for stable regulation.
It operates in continuous conduction mode (CCM) up to ~500 mA and transitions seamlessly to pulse-skipping Eco-Mode™ below the CCM boundary, maintaining high efficiency down to microamp-level loads. The device features a fixed 2-ms internal soft-start, UVLO with 200-mV hysteresis, and valley-current-based overcurrent protection with nonlatching hiccup recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 17 V - Supports wide industrial and broadband power bus inputs; UVLO threshold at 4.35 V (rising) ensures reliable startup. |
| Output Current | 500 mA continuous - Sustains full rated load without derating at TJ ≤ 125°C with proper PCB thermal design (RθJA = 166.8°C/W). |
| Switching Frequency | 600 kHz (pseudo-fixed) - Enables compact magnetics and filtering; frequency varies <±5% across VIN and IOUT per adaptive on-time control. |
| Voltage Reference | 0.8 V ±1.3% over –40°C to 125°C - Sets output accuracy baseline; enables precise 0.8–6.5 V programming via external resistor divider. |
| High-Side RDS(on) | 0.95 Ω (typ) at VIN = 12 V - Limits conduction loss at mid-load; contributes to >90% peak efficiency at 12-V input / 1.05-V output. |
| Low-Side RDS(on) | 0.33 Ω (typ) at VIN = 12 V - Reduces synchronous rectification loss; critical for Eco-Mode™ efficiency at light loads. |
| Soft-Start Time | 2 ms (internal, fixed) - Controls inrush current during startup; supports safe ramp-up into prebiased outputs without sinking current. |
| Thermal Shutdown | 170°C (trip), 160°C (hysteresis) - Protects against sustained overload or poor heatsinking; nonlatching recovery after cooldown. |
Pinout & Package
TPS560200DBVT is housed in a 5-pin SOT-23 package (2.90 mm × 1.60 mm body size) with exposed thermal pad connected to GND for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-high logic control; floats to enable; threshold 1.29 V (rising); draws <100 µA - allows simple ON/OFF sequencing with MCU GPIO or resistor pull-up. |
| GND (Pin 2) | Power and signal ground | Common return for control circuitry and low-side MOSFET; must be tied directly to PCB ground plane under IC for thermal and noise integrity. |
| PH (Pin 3) | Switch node | Drives external inductor; connects internally to drain of high-side and source of low-side MOSFETs - requires tight layout to minimize EMI and ringing. |
| VIN (Pin 4) | Power input | Supplies internal control circuitry and high-side gate driver; requires local 10-µF ceramic bypass capacitor placed adjacent to pin. |
| VSENSE (Pin 5) | Feedback input | Monitors output voltage via resistor divider; 0.8-V reference sets regulation point; input bias current <100 nA minimizes divider error. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ Control Mode | Eliminates need for external compensation components while delivering <10-µs transient response to 50% load steps - reduces BOM count and layout complexity. |
| Advanced Eco-Mode™ | Enables >85% efficiency at 1-mA load by entering pulse-skipping operation - extends battery life in always-on standby circuits. |
| Prebiased Soft-Start | Prevents reverse current flow during startup when VOUT is already present - avoids system brownout or damage to downstream regulators. |
| Integrated Power MOSFETs | 0.95-Ω HS + 0.33-Ω LS FETs co-packaged in SOT-23 - eliminates discrete FET selection, gate drive design, and layout mismatch risks. |
| Ceramic/Polymer Capacitor Support | Proprietary ripple emulation circuit stabilizes regulation with zero-ESR ceramics or low-ESR polymer caps - enables smaller, lower-cost output filters. |
| Safety Protections | Includes thermal shutdown (170°C), cycle-by-cycle overcurrent protection, and input UVLO - ensures robust operation in unregulated or noisy supply environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562201DDCR | 2-A rating, same 4.5–17-V input, identical D-CAP2™ control and SOT-563 package; higher RDS(on) (0.115 Ω HS / 0.07 Ω LS). | Targets higher-current rails (e.g., DDR memory termination); not drop-in due to different pinout and thermal pad configuration. | Select when >500-mA output is required and board space permits SOT-563; verify layout compatibility and thermal margin. |
| MP2307DN-LF-Z | 2-A, 4.5–23-V input, external compensation required, SOIC-8 package; lacks Eco-Mode™, soft-start, and prebias support. | Suitable for cost-sensitive industrial supplies where light-load efficiency and safe startup are secondary. | Choose only if BOM cost is primary constraint and design can accommodate external compensation and larger footprint. |
Compared with TPS560200DBVT, TPS562201DDCR offers higher current capacity but requires PCB redesign, while MP2307DN-LF-Z trades integration and advanced features for lower unit cost - making TPS560200DBVT optimal for space-constrained, efficiency-critical 500-mA applications.

FAQ
What is the maximum recommended input voltage for the TPS560200DBVT?
The absolute maximum input voltage for the TPS560200DBVT is 20 V, but the recommended operating range is strictly 4.5 V to 17 V per datasheet Section 6.3. Exceeding 17 V may trigger internal UVLO hysteresis or reduce reliability; operation at 20 V is limited to transient stress conditions only and not intended for continuous use. Always maintain input filtering to suppress spikes beyond 17 V.
Does the TPS560200DBVT require external compensation components?
No, the TPS560200DBVT does not require external compensation components. Its D-CAP2™ control architecture integrates internal compensation, enabling stable operation with ceramic or polymer output capacitors without adding RC networks or type-II/III compensators - confirmed in datasheet Sections 7.3.1 and 8.2.2.1.
Can the TPS560200DBVT safely start up when the output is already biased?
Yes, the TPS560200DBVT supports safe startup into prebiased outputs via its proprietary prebiased soft-start circuit. When EN goes high and VSENSE > internal soft-start voltage, the low-side FET is activated gradually with increasing on-time to avoid sinking current from the precharged rail - detailed in Section 7.3.4 and validated in Figure 15 of the datasheet.
What output capacitor types are compatible with the TPS560200DBVT?
The TPS560200DBVT is explicitly designed to work with ultra-low-ESR ceramic capacitors (e.g., X5R/X7R MLCCs) and low-ESR polymer capacitors (e.g., POSCAP, SP-CAP), as stated in Sections 3 and 7.1. Its internal ripple emulation circuit ensures stability with near-zero ESR, eliminating the need for intentional ESR in the output filter.
How does the Advanced Eco-Mode™ improve efficiency at light loads?
Advanced Eco-Mode™ improves light-load efficiency by disabling pulse-width modulation and entering pulse-skipping mode when inductor valley current reaches zero. This reduces switching losses and gate drive power, enabling >85% efficiency at 1-mA output - verified in Figure 9 (Light-Load Efficiency) and described in Section 7.3.3 of the TPS560200DBVT datasheet.
