Product details
Overview
TPS562242DRLR from Texas Instruments is a 2-A synchronous buck DC/DC converter in SOT-563 package, operating from 3 V to 17 V input and delivering 0.8 V to 10 V output with ±1% reference accuracy at 25°C, 1.4-MHz switching frequency, and integrated 55.0-mΩ high-side / 24.3-mΩ low-side MOSFETs - used in Wi-Fi access points and STB power rails.
For engineers reviewing the TPS562242DRLR datasheet, TPS562242DRLR pinout, TPS562242DRLR application, or TPS562242DRLR equivalent, key selection criteria include D-CAP3™ control mode for no-external-compensation design, Eco-mode efficiency at light load, 1.6-ms fixed soft-start, non-latch UVLO/OVP/OTP protection, and 94% maximum duty cycle operation.
Technical Context
The TPS562242DRLR implements D-CAP3™ adaptive on-time control with internal ripple generation, enabling stable regulation with ultra-low-ESR ceramic capacitors and eliminating external compensation networks. Its control loop supports seamless CCM-to-DCM transition and maintains pseudo-fixed frequency across input voltage variations.
It integrates full-cycle protection: cycle-by-cycle overcurrent detection via valley-current sensing on the low-side FET, hiccup-mode undervoltage protection with 220-μs deglitch and 14-ms restart delay, and non-latch thermal shutdown at 155°C with 20°C hysteresis - all implemented without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports wide-input industrial and broadband power rails without pre-regulation. |
| Output Current | 2 A continuous - sufficient for SoC core or I/O rail in STB, WLAN, and appliance applications. |
| Switching Frequency | 1.4 MHz typical - enables compact magnetics and reduces EMI filter size in space-constrained layouts. |
| Reference Voltage | 0.8 V ±1% at 25°C - ensures precise output regulation for low-voltage digital loads (e.g., 1.05 V, 3.3 V). |
| Quiescent Current | 100 μA in Eco-mode - extends battery life or reduces standby loss in always-on consumer devices. |
| Max Duty Cycle | 94% - allows high step-down ratios (e.g., 12 V → 1.05 V) while maintaining regulation under low-VIN conditions. |
| MOSFET RDS(on) | 55.0 mΩ HS / 24.3 mΩ LS at 25°C - minimizes conduction loss and improves full-load efficiency up to 94%. |
| Soft-Start Time | 1.6 ms fixed - prevents inrush current and ensures controlled power-up of downstream logic and memory. |
Pinout & Package
TPS562242DRLR is housed in a 1.6 mm × 1.6 mm, 6-pin SOT-563 (DRL) package optimized for high power density and thermal performance on 2-layer PCBs (RθJA_effective = 74°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power input | Connects to bulk input capacitor; supplies gate drive and controller bias; rated to 18 V absolute max. |
| SW (Pin 2) | Power switch node | Drives external inductor; carries high di/dt; requires tight layout to minimize EMI and voltage spikes. |
| GND (Pin 3) | Power and signal ground | Common return for controller, FETs, and feedback; must be low-impedance connection to thermal pad. |
| BST (Pin 4) | Bootstrap supply | Connects 100-nF ceramic cap to SW; enables high-side FET gate drive; can be left floating if not needed. |
| EN (Pin 5) | Enable control | Logic-level input (1.17 V typ enable threshold); open-drain compatible; supports sequencing and power-down. |
| FB (Pin 6) | Feedback input | Senses output voltage via resistor divider; references internal 0.8-V bandgap; determines final regulated output. |
Key Features
| Feature | Design Value |
|---|---|
| D-CAP3™ Control Mode | Enables stable operation with ceramic output capacitors and zero external compensation components - reducing BOM count and layout complexity. |
| Eco-mode Operation | Maintains >80% efficiency at 1 mA load by entering discontinuous conduction mode - critical for low-power standby states in connected devices. |
| Prebiased Output Startup | Supports safe start-up when output capacitor is precharged - avoids reverse current flow and protects downstream circuitry. |
| Non-Latch Protection Suite | Includes OVP (115% trip), UVP (60% trip), OTP (155°C), and cycle-by-cycle OCP - recovers automatically after fault removal without system reset. |
| Large-Duty-Cycle Support | Extends on-time smoothly down to ~700 kHz to sustain regulation at VIN/VOUT < 1.6 - essential for high-ratio conversion in compact designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS562202DRLR | Same SOT-563 package and pinout; lower 1.2-A output current; identical D-CAP3™ control and Eco-mode. | Not suitable for 2-A continuous loads; limited to lighter-duty applications like IoT sensors or auxiliary rails. | Select only when output current requirement is ≤1.2 A and cost optimization is prioritized over headroom. |
| MP2315GJ-Z | Monolithic 2-A buck in SOT-563; 2.5–18-V input; 0.8-V reference; but uses current-mode control and requires external compensation. | Lacks D-CAP3™ simplicity; needs additional resistors/capacitors for loop stability; higher design effort for same performance. | Consider only if multi-source availability or specific qualification requirements favor Monolithic Power Systems. |
Compared with TPS562242DRLR, TPS562202DRLR offers identical footprint and features at reduced current capability, while MP2315GJ-Z trades design simplicity for alternate vendor sourcing - making TPS562242DRLR optimal for new designs demanding 2-A output, minimal BOM, and proven D-CAP3™ transient response.

FAQ
What is the recommended input capacitor configuration for TPS562242DRLR?
TI recommends a minimum 10-μF ceramic input capacitor placed close to the VIN and GND pins of the TPS562242DRLR, plus an additional 0.1-μF high-frequency ceramic capacitor from VIN to GND. The voltage rating must exceed the maximum input voltage (17 V), and low-ESR X5R/X7R dielectrics are preferred to handle peak switching currents and reduce input ripple. This configuration ensures stable operation and meets EMI requirements per CISPR-22 Class B.
Does TPS562242DRLR support output voltage sequencing with other rails?
Yes, TPS562242DRLR supports controlled sequencing via its EN pin: applying a delayed or ramped enable signal coordinates power-up order with other regulators. The EN threshold is 1.17 V (typ), with 170-mV hysteresis, allowing compatibility with standard GPIOs or dedicated sequencer ICs. This capability is verified in TPS562242DRLR reference designs for STB and modem applications where core voltage must ramp before I/O rails.
Can TPS562242DRLR operate with a 3.3-V input supply?
Yes, TPS562242DRLR operates down to 3 V input, with validated performance at 3 V in efficiency curves (Figure 6-7) and electrical characteristics. At 3 V, the high-side RDS(on) increases to 67.5 mΩ and low-side to 30.2 mΩ, slightly reducing full-load efficiency - but regulation remains stable across the full temperature range (–40°C to 125°C) and output range (0.8 V to 10 V).
What thermal derating applies to TPS562242DRLR in a 2-layer PCB design?
On a standard 2-layer evaluation board (2-oz copper), TPS562242DRLR has RθJA_effective = 74°C/W. At 2 A load and 12 V input, typical power dissipation is ~0.35 W, resulting in ~26°C junction rise above ambient. Derating begins above 100°C junction temperature; full 2-A output is guaranteed up to 85°C ambient with adequate airflow or thermal relief - confirmed in TI's TPS562242EVM test data.
Is WEBENCH® Power Designer support available for TPS562242DRLR?
Yes, TPS562242DRLR is fully supported in TI's WEBENCH® Power Designer tool. Users can enter input/output specifications (e.g., 12 V → 3.3 V @ 2 A), optimize for efficiency or footprint, simulate transient response and thermal performance, and export validated schematics and BOMs - all using the exact TPS562242DRLR model with real component libraries and pricing.
