Product details
Overview
TPS562207SDRLR from Texas Instruments is a 2-A synchronous buck converter in SOT563 (DRL) package, operating in Forced Continuous Conduction Mode (FCCM) with D-CAP2™ control. It delivers regulated output from 4.3 V to 17 V input, supports 0.804 V–7 V output range, features 580-kHz fixed switching frequency, and integrates 140-mΩ high-side and 84-mΩ low-side MOSFETs for compact DC/DC conversion in space-constrained consumer power rails.
For engineers reviewing the TPS562207SDRLR datasheet, TPS562207SDRLR pinout, TPS562207SDRLR application, or TPS562207SDRLR equivalent, key selection criteria include FCCM operation for low output ripple, D-CAP2™ fast transient response without external compensation, 1.5% feedback accuracy at 25°C, pre-bias start-up support, and thermal/UVLO/hiccup protections for reliable embedded power delivery.
Technical Context
The TPS562207SDRLR implements adaptive on-time D-CAP2™ control, combining internal ramp injection with pseudo-fixed-frequency PWM to stabilize output with ceramic or polymer capacitors-no external compensation required. Its FCCM mode maintains constant 580-kHz switching across load and line variations, minimizing output voltage ripple and simplifying EMI filtering.
Protection architecture includes cycle-by-cycle valley-current overcurrent detection, non-latching thermal shutdown (160°C trip), non-latching undervoltage lockout (4.3 V enable threshold), and hiccup-mode recovery after overcurrent events. Soft-start is fixed at 1.2 ms, and the device supports pre-biased output startup by initiating switching only when internal reference exceeds FB voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.3 V to 17 V - Enables direct integration into 5 V, 9 V, 12 V, and 15 V intermediate bus systems without pre-regulation. |
| Output Voltage Range | 0.804 V to 7 V - Programmable via resistor divider; covers core logic (0.8–1.2 V), I/O (1.8–3.3 V), and auxiliary rails (5 V). |
| Switching Frequency | 580 kHz - Fixed FCCM operation ensures predictable EMI profile and consistent output ripple amplitude. |
| Max Output Current | 2 A - Delivers sufficient current for SoC cores, FPGAs, and DSPs in compact consumer electronics. |
| Feedback Accuracy | ±1.5% at 25°C - Ensures tight regulation tolerance for sensitive analog and mixed-signal circuits. |
| Shutdown Current | <3 µA - Enables ultra-low-power standby in always-on subsystems such as remote controls or smart speaker wake-on-voice circuitry. |
| Thermal Protection | Non-latch 160°C shutdown with 25°C hysteresis - Prevents permanent damage during sustained overload while allowing automatic recovery. |
Pinout & Package
SOT563 (DRL) package: 6-pin, 1.6 mm × 1.6 mm body size, surface-mount, thermally enhanced layout with exposed pad (not electrically connected per datasheet). Designed for high-density PCBs requiring minimal footprint and efficient heat dissipation via GND-connected copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input supply rail | Accepts 4.3–17 V DC; requires local 10-µF ceramic + 0.1-µF HF decoupling; wide trace recommended for low impedance and thermal relief. |
| SW (Pin 2) | Switch node | Connects between integrated high-side and low-side NFETs; critical high-dV/dt node-must be short, wide, and isolated from sensitive traces. |
| GND (Pin 3) | Power and signal ground | Common return for low-side FET source and controller ground; Kelvin connection to FB resistor divider required for accuracy. |
| BST (Pin 4) | Bootstrap supply | Drives high-side gate; requires 0.1-µF ceramic capacitor to SW-placement must minimize loop inductance to prevent shoot-through. |
| EN (Pin 5) | Enable control | Active-high logic input (1.35–1.6 V threshold); internal 225–900 kΩ pull-down enables default disable; supports sequencing and power gating. |
| FB (Pin 6) | Feedback input | Monitors output via resistor divider; ±0.1 µA input bias enables use of high-value resistors to reduce quiescent current without sacrificing noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control mode | Enables stable operation with ultra-low-ESR ceramic or polymer output capacitors-eliminates need for external compensation network. |
| Forced Continuous Conduction Mode (FCCM) | Maintains fixed 580-kHz switching under all load conditions, delivering consistent output ripple and predictable EMI behavior for noise-sensitive applications. |
| Pre-bias start-up support | Allows safe startup into an already charged output rail-critical for hot-swap, power sequencing, and multi-rail systems where VOUT may be powered before VIN. |
| Cycle-by-cycle overcurrent protection | Valley-current sensing on low-side FET provides fast, accurate current limiting without external sense resistors-reduces BOM count and board area. |
| Fixed 1.2-ms soft-start | Internally ramps reference voltage linearly to limit inrush current and prevent output overshoot during power-up-no external timing components needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562210DRLR | Higher 3-A rating, same D-CAP2™ control and SOT563 package; 120-mΩ/70-mΩ FETs; 650-kHz switching. | Supports higher current loads but draws ~10% more quiescent current in light-load operation. | Select when output current demand exceeds 2 A or tighter output voltage regulation (±1%) is required. |
| MP2315GJ-Z | Monolithic 2-A buck with 120-mΩ/70-mΩ FETs; 500-kHz fixed frequency; no pre-bias start-up; different pinout (VIN/SW/GND/EN/FS/FB). | Lacks D-CAP2™ adaptive control-requires external compensation for ceramic caps; no hiccup-mode OCP. | Choose for cost-sensitive designs where transient performance is secondary and layout flexibility allows rework for alternate pinout. |
Compared with TPS562207SDRLR, TPS562210DRLR offers higher current headroom and tighter feedback accuracy but increases light-load quiescent consumption, while MP2315GJ-Z trades advanced control features for lower unit cost and simplified BOM-making it suitable only where D-CAP2™ benefits and hiccup protection are not mandatory.

FAQ
What is the maximum input voltage rating for the TPS562207SDRLR?
The TPS562207SDRLR has an absolute maximum input voltage rating of 19 V on the VIN pin, but its recommended operating input voltage range is strictly 4.3 V to 17 V per datasheet Section 7.3. Exceeding 17 V during normal operation risks violating recommended conditions and may impact reliability or lifetime, even if below the absolute maximum stress limit.
Does the TPS562207SDRLR support pre-biased output startup?
Yes, the TPS562207SDRLR supports pre-biased start-up. As described in Section 8.3.2, it initiates switching only after the internal soft-start reference voltage exceeds the FB pin voltage-preventing reverse current flow and ensuring controlled ramp-up even when the output capacitor is initially charged.
What package type and dimensions does the TPS562207SDRLR use?
The TPS562207SDRLR uses the SOT563 (DRL) package: a 6-pin, 1.6 mm × 1.6 mm body-size surface-mount package with 0.5-mm pitch. Per TI's Mechanical, Packaging, and Orderable Information, it is specified for –40°C to 125°C junction temperature and features an exposed thermal pad (non-electrical) for improved heat dissipation.
How does the D-CAP2™ control mode benefit designs using the TPS562207SDRLR?
The D-CAP2™ control mode in the TPS562207SDRLR eliminates the need for external compensation components by integrating adaptive on-time control with internal ramp injection. This enables stable regulation with ultra-low-ESR ceramic or specialty polymer output capacitors-reducing solution size, bill-of-materials count, and design validation effort while delivering fast transient response.
What protection features are integrated into the TPS562207SDRLR?
The TPS562207SDRLR integrates cycle-by-cycle overcurrent limit, hiccup-mode overcurrent protection, non-latching thermal shutdown (160°C trip), non-latching output undervoltage protection (UVP), and input undervoltage lockout (UVLO) with 4.3 V turn-on threshold. All protections auto-recover without external intervention unless fault condition persists.
