Product details
Overview
TPS562202DRLR from Texas Instruments is a 2-A synchronous buck DC-DC converter in SOT563 (DRL) package, featuring integrated 140-mΩ high-side and 84-mΩ low-side MOSFETs, D-CAP2™ control mode for fast transient response, and ECO mode for high light-load efficiency. It operates from 4.3 V to 17 V input and delivers adjustable output from 0.804 V to 7 V - used in TV power rails, smart speaker core supplies, and wired networking PHY voltage domains.
For engineers reviewing the TPS562202DRLR datasheet, TPS562202DRLR pinout, TPS562202DRLR application, or TPS562202DRLR equivalent, key selection criteria include its 580-kHz fixed switching frequency, 1.2-ms internal soft start, cycle-by-cycle overcurrent protection with hiccup-mode recovery, non-latching UVP/TSD, and support for pre-bias start-up in compact 1.6 mm × 1.6 mm SOT563 layout.
Technical Context
The TPS562202DRLR implements adaptive on-time D-CAP2™ control, combining internal compensation with pseudo-fixed-frequency operation across 4.3–17 V input range - enabling stable regulation with ceramic or polymer output capacitors without external loop compensation. Its valley-current sensing enables precise cycle-by-cycle current limiting at 2.24–4 A.
ECO mode dynamically reduces switching frequency under light load by entering discontinuous conduction mode while maintaining high efficiency; thermal shutdown triggers at 160°C with 25°C hysteresis, and UVLO activates at 4.3 V with 0.4 V hysteresis. The device supports 1.2-ms fixed soft start and pre-biased output startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SOT563 (DRL) package: 6-pin, 1.6 mm × 1.6 mm body, 0.5-mm pitch, exposed thermal pad (connected to GND). Designed for high-density PCB layouts with minimal footprint and thermal resistance (RθJA = 141°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input power supply | Primary DC input connection; requires local 10-µF ceramic + 0.1-µF high-frequency decoupling. |
| SW | Switch node | Connection between high- and low-side MOSFETs; drives external inductor and BST capacitor. |
| GND | Power and signal ground | Common return for low-side FET source and controller circuitry; Kelvin feedback must tie to this pin. |
| BST | Bootstrap supply | Supplies gate drive for high-side FET; requires 0.1-µF ceramic capacitor to SW pin. |
| EN | Enable control | Active-high logic input (1.35–1.6 V threshold); internal 225–900 kΩ pull-down enables default disable. |
| FB | Feedback input | Resistor-divider input for output voltage regulation; ±0.1 µA bias current enables high-resistor-divider use. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP2™ control mode | Enables stable operation with zero-ESR ceramic capacitors and eliminates need for external compensation network. |
| ECO mode | Reduces switching frequency proportionally to load current below ~300 mA, sustaining >85% efficiency at 10 mA output. |
| Pre-bias start-up support | Allows safe ramp-up when output capacitor is pre-charged, preventing reverse current flow into the converter. |
| Hiccup-mode OCP | Enters 2.2-ms fault-on / 18-ms restart cycle upon sustained overcurrent, protecting MOSFETs and PCB traces. |
| Non-latching UVP/TSD | Shuts down temporarily on undervoltage or overtemperature, then resumes operation once condition clears - no manual reset 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 |
|---|---|---|---|
| TPS562207DRLR | Uses FCCM (forced continuous conduction mode) instead of ECO mode; higher light-load quiescent current (~15 µA vs <3 µA). | Better for noise-sensitive applications requiring constant-frequency operation; less efficient below 100 mA. | Select when EMI filtering demands fixed frequency or when output ripple must remain predictable across full load range. |
| MP2315GJ-Z | Monolithic 2-A buck with 4.5–28 V input, 500-kHz switching, but lacks pre-bias start-up and has ±3% FB accuracy vs ±2%. | Broader input range suits 24-V industrial systems; lower accuracy may require tighter resistor tolerance for precision outputs. | Choose for higher input voltage margin or where MPQ-grade qualification is required; verify soft-start timing and hiccup behavior in final design. |
Compared with TPS562202DRLR, TPS562207DRLR trades light-load efficiency for EMI predictability, while MP2315GJ-Z extends input range at the cost of regulation accuracy and startup robustness - making TPS562202DRLR optimal for space-constrained, efficiency-critical consumer electronics with 12-V input rails.

FAQ
What is the maximum output current capability of the TPS562202DRLR?
The TPS562202DRLR is rated for 2 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper layout, adequate copper area). Peak current capability reaches 3.1 A before cycle-by-cycle overcurrent protection engages, as confirmed in electrical characteristics tables. Derating applies above 85°C ambient or with insufficient thermal relief.
Does the TPS562202DRLR support pre-biased output startup?
Yes, the TPS562202DRLR supports pre-biased soft start: when the FB voltage exceeds the internal reference at power-up, the device delays switching until the internal soft-start ramp surpasses the present FB level, preventing reverse current flow and ensuring monotonic output rise. This behavior is explicitly verified in Section 8.3.3 of the datasheet.
What is the purpose of the BST pin on the TPS562202DRLR?
On the TPS562202DRLR, the BST (bootstrap) pin supplies gate drive voltage to the high-side MOSFET. A 0.1-µF ceramic capacitor must be placed between BST and SW pins to generate the required floating voltage above VIN. This configuration enables efficient high-side FET turn-on without an external charge pump or isolated supply.
How does ECO mode improve efficiency in the TPS562202DRLR?
ECO mode in the TPS562202DRLR improves light-load efficiency by transitioning from continuous conduction mode (CCM) to discontinuous conduction mode (DCM) as output current drops below ~300 mA. Switching frequency scales inversely with load, reducing switching losses while maintaining regulation - achieving >85% efficiency at 10 mA versus ~65% in forced CCM.
What protection features are integrated into the TPS562202DRLR?
The TPS562202DRLR integrates cycle-by-cycle overcurrent limit, hiccup-mode overcurrent protection, non-latching undervoltage protection (UVP), non-latching thermal shutdown (TSD), and undervoltage lockout (UVLO). All protections are fully specified in Section 7.5 and validated across –40°C to 125°C junction temperature range.
