Product details
Overview
TPS62825DMQR from Texas Instruments is a synchronous step-down DC/DC converter optimized for 2A output current, operating from 2.4V to 5.5V input and delivering adjustable 0.6V–4.0V output with ±1% accuracy over –40°C to 125°C. It integrates 26mΩ high-side and 25mΩ low-side MOSFETs, uses DCS-Control topology for fast transient response, and targets space-constrained portable electronics requiring ultra-low quiescent current (4μA) and high efficiency (up to 97%).
For engineers reviewing the TPS62825DMQR datasheet, TPS62825DMQR pinout, TPS62825DMQR application, or TPS62825DMQR equivalent, this page delivers verified specifications, validated pin functions, confirmed thermal and electrical behavior at 2A load, and real-world implementation guidance for battery-powered point-of-load systems.
Technical Context
The TPS62825DMQR implements adaptive constant-on-time DCS-Control with seamless PWM-to-PSM mode transition-maintaining regulation while optimizing light-load efficiency. Its internal reference enables 0.6V minimum output with 1% feedback accuracy across full temperature range, and 100% duty-cycle operation supports ultra-low dropout in near-input-voltage conditions.
Thermal protection includes 150°C junction shutdown with 20°C hysteresis; fault handling uses hiccup-mode short-circuit protection triggered after 32 switching cycles. The device features active output discharge via SW pin during disable, power-good open-drain signaling with 100μs rise-edge blanking, and undervoltage lockout at 2.2V (160mV hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 2 A continuous-supports compact 2A PoL designs without external current-sense or thermal derating. |
| Input voltage range | 2.4 V to 5.5 V-compatible with single-cell Li-ion, USB PD, and industrial 3.3V/5V rails. |
| Output voltage range | 0.6 V to 4.0 V adjustable-enables direct core supply for modern SoCs, FPGAs, and DSPs. |
| Feedback accuracy | ±1 % over –40°C to 125°C-ensures stable regulation under thermal stress without calibration. |
| Quiescent current | 4 μA in PSM mode-extends battery runtime in always-on sensor nodes and IoT endpoints. |
| Switching frequency | 2.2 MHz nominal-permits use of sub-1μH inductors and reduces EMI filter size. |
| Package | 6-pin 1.5 mm × 1.5 mm VSON-HR (DMQ)-enables <1.0 mm² footprint with exposed thermal pad. |
| Efficiency peak | Up to 97 % at mid-load-minimizes heat generation in sealed enclosures and stacked PCBs. |
Pinout & Package
TPS62825DMQR uses a 6-pin VSON-HR (DMQ) package with 1.5 mm × 1.5 mm body and wettable flank leads for automated optical inspection. Thermal pad on underside requires solder connection to PCB ground plane for optimal thermal performance (RθJA = 129.5°C/W, RθJB = 33.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0 V min); 0.05 μA shutdown current prevents battery drain. |
| PG | Power-good open-drain output | Sinks up to 1 mA; signals valid regulation (94–98% VFB) with 100 μs deglitch; requires external pull-up ≤5.5 V. |
| FB | Feedback input | Monitors output via resistor divider; 600 mV nominal reference enables precise 0.6 V–4.0 V adjustment. |
| GND | Ground reference | Primary return path for control circuitry and power stage; must be connected to thermal pad for thermal integrity. |
| SW | Switch node | Connects to inductor; carries high di/dt switching current; requires tight layout to minimize EMI and ringing. |
| VIN | Input power supply | Accepts 2.4–5.5 V; requires local 4.7 μF ceramic capacitor placed within 3 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Delivers <10 μs load transient response with minimal output capacitance-reducing BOM count and board area. |
| 100% duty-cycle operation | Enables dropout as low as IOUT × RDS(on) + IOUT × RL, critical for battery-powered systems nearing end-of-discharge. |
| Active output discharge | Drains output to safe level within milliseconds after disable-prevents back-powering of downstream circuitry. |
| Hiccup short-circuit protection | Limiting power delivery to ~1/10th normal during overload avoids thermal runaway and enables self-recovery. |
| Forced-PWM option (A-version) | Eliminates PSM-induced frequency variation-essential for noise-sensitive analog circuits and EMC compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62825ADMQ | Forced-PWM only (no PSM), 8 μA IQ, identical 2A rating and package. | Better suited for noise-sensitive analog/RF loads where switching frequency stability is mandatory. | Select when ripple <10 mV and fixed fSW outweigh ultra-low IQ requirements. |
| MP2152GQZ-P | 2A, 2.5–5.5V input, 3.0 MHz fSW, 15 μA IQ, no PG or active discharge. | Lacks power-good signaling and output discharge-requires external sequencing and hold-up circuitry. | Choose for cost-sensitive, non-safety-critical applications where PG and discharge are not required. |
Compared with TPS62825DMQR, TPS62825ADMQ trades 4 μA quiescent current for guaranteed CCM operation, while MP2152GQZ-P reduces solution cost but omits key system-level features like PG and active discharge-requiring additional discrete components for robust power management.

FAQ
What is the maximum continuous output current of the TPS62825DMQR?
The TPS62825DMQR is rated for 2 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). This rating is validated across the full input range (2.4 V–5.5 V) and output range (0.6 V–4.0 V), with derating required only above 125°C junction temperature or with inadequate copper area.
Does the TPS62825DMQR support adjustable output voltage?
Yes, the TPS62825DMQR supports fully adjustable output voltage from 0.6 V to 4.0 V using an external resistor divider connected to the FB pin. The internal 600 mV reference enables precise setting via Equation R1 = R2 × (VOUT/0.6 V − 1), with R2 recommended at 100 kΩ for optimal noise immunity and light-load efficiency.
How does the power-good (PG) pin function on the TPS62825DMQR?
The PG pin on the TPS62825DMQR is an open-drain output that goes high-impedance when VFB reaches 94–98% of its target value, indicating valid regulation. It sinks up to 1 mA and requires an external pull-up resistor (≤5.5 V). PG asserts low during enable/disable transitions, UVLO, thermal shutdown, or output undervoltage-enabling reliable rail sequencing in multi-converter systems.
What thermal protection mechanisms does the TPS62825DMQR include?
The TPS62825DMQR incorporates thermal shutdown at 150°C junction temperature with 20°C hysteresis, plus hiccup-mode short-circuit protection that disables the high-side FET for 100 μs after 32 consecutive current-limit events. These features prevent permanent damage during sustained overload or poor heatsinking, allowing automatic recovery once temperature or fault condition subsides.
Can the TPS62825DMQR operate with 100% duty cycle?
Yes, the TPS62825DMQR supports true 100% duty-cycle operation: when VOUT approaches VIN, the high-side FET remains continuously on while the low-side FET turns off. Dropout is determined solely by IOUT × RDS(on) + IOUT × RL, enabling efficient operation near battery end-of-life or in low-VIN scenarios without output collapse.
