Product details
Overview
TPS62824ADMQR from Texas Instruments is a synchronous step-down DC/DC converter with forced-PWM operation, delivering 1A output current at up to 97% efficiency. It features 1% output voltage accuracy (–40°C to 125°C), 2.2MHz fixed switching frequency, 4μA quiescent current in shutdown, and integrated power MOSFETs (26mΩ high-side, 25mΩ low-side). It serves as a compact, high-density point-of-load regulator in battery-powered industrial and embedded systems.
For engineers reviewing the TPS62824ADMQR datasheet, TPS62824ADMQR pinout, TPS62824ADMQR application, or TPS62824ADMQR equivalent, key selection criteria include forced-PWM mode for low-output-ripple operation, 1.5mm × 1.5mm VSON-HR package constraints, 0.6V–4V adjustable output capability, and compatibility with 470nH inductors and minimal external components (single 4.7µF input cap, dual 10µF or single 22µF output caps).
Technical Context
The TPS62824ADMQR implements DCS-Control topology with adaptive constant-on-time modulation, enabling fast transient response and stable 2.2MHz switching across 2.4V–5.5V input range. Its forced-PWM architecture maintains continuous conduction mode (CCM) under all load conditions, eliminating PSM-induced frequency variation and ensuring predictable EMI behavior.
It integrates active output discharge, power-good open-drain signaling with 100µs deglitch delay, thermal shutdown (150°C trip, 20°C hysteresis), and hiccup-mode short-circuit protection. The device supports 100% duty cycle operation for ultra-low dropout and starts into pre-biased outputs via internal soft-start (1.25ms to 95% VOUT).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4V to 5.5V - supports single-cell Li-ion, USB, and industrial 3.3V/5V rails without external LDO pre-regulation. |
| Output Current | 1A continuous - sufficient for powering FPGA I/O banks, microcontroller cores, or sensor signal chains. |
| Output Voltage Accuracy | ±1% over –40°C to 125°C - enables precise regulation of sensitive analog or RF circuitry without post-regulation trimming. |
| Quiescent Current | 4μA in shutdown - minimizes standby power loss in always-on subsystems like real-time clocks or wake-on-event logic. |
| Switching Frequency | 2.2MHz nominal - allows use of sub-1μH inductors and reduces output capacitor count while maintaining EMI compliance. |
| Package | 6-pin 1.5mm × 1.5mm VSON-HR (DMQ) - delivers 0.56 mm² footprint and 0.5mm height for ultra-thin portable designs. |
| Efficiency | Up to 97% at mid-load - reduces thermal stress in sealed enclosures and extends battery runtime in portable electronics. |
Pinout & Package
TPS62824ADMQR uses a 6-pin VSON-HR (DMQ) package with wettable flanks, 0.4mm pitch, and exposed thermal pad. The package measures 1.5mm × 1.5mm × 0.5mm (L × W × H) and is optimized for automated optical inspection (AOI) and thermal performance on 2-layer PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0V min); must be pulled high to operate; floating prohibited. |
| PG | Power-good open-drain output | Signals valid regulation (94–98% VFB rising, 90–94% falling); requires external pullup ≤5.5V; 100µs blanking on rise. |
| FB | Feedback input | Sets output voltage via resistor divider (VFB = 600mV ±1%); leakage <0.05μA enables high-R dividers. |
| GND | Power and signal ground | Common reference for control circuitry and power stage; must connect directly to thermal pad. |
| SW | Switch node | Connects to inductor; carries high di/dt PWM waveform; requires tight layout to minimize EMI and ringing. |
| VIN | Input power supply | Accepts 2.4–5.5V; requires local 4.7μF ceramic decoupling placed within 2mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Forced-PWM operation | Maintains fixed 2.2MHz frequency and CCM across full 0–1A load range, eliminating audible noise and simplifying EMI filtering. |
| Active output discharge | Internally sinks up to 400mA through SW pin during shutdown, preventing residual voltage hold-up on downstream circuits. |
| DCS-Control topology | Delivers <10μs load transient response with <1% undershoot/overshoot, critical for processor core rail stability. |
| 100% duty cycle mode | Enables dropout as low as IOUT × RDS(on)_HS + IL × DCR_L, supporting applications where VIN ≈ VOUT (e.g., 3.3V → 3.0V). |
| Hiccup short-circuit protection | Limiting fault power to ~100mW average during sustained overload, preventing thermal runaway without latch-off. |

FAQ
What is the switching frequency of the TPS62824ADMQR and how stable is it?
The TPS62824ADMQR operates at a nominal 2.2MHz switching frequency in forced-PWM mode. Its DCS-Control topology maintains this frequency with minimal variation across input voltage (2.4V–5.5V) and load (0–1A), ensuring predictable EMI filter design and consistent transient response. Unlike PSM variants, it does not throttle frequency at light loads.
Does the TPS62824ADMQR support adjustable output voltage, and what is the feedback reference voltage?
Yes, the TPS62824ADMQR supports adjustable output voltage from 0.6V to 4.0V using an external resistor divider on the FB pin. Its internal feedback reference voltage is precisely 600mV ±1% over –40°C to 125°C, enabling high-accuracy regulation without calibration. Fixed-output versions (e.g., TPS6282533DMQR) omit the divider.
How does the TPS62824ADMQR handle short-circuit conditions?
The TPS62824ADMQR employs hiccup-mode short-circuit protection: upon detecting overcurrent for 32 consecutive switching cycles (~13μs), it disables the high-side FET for ~100μs, allowing inductor current to decay, then restarts with soft-start. This limits average fault power and prevents thermal damage without latching off permanently.
Can the TPS62824ADMQR start into a pre-biased output, and what is its soft-start time?
Yes, the TPS62824ADMQR supports start-up into a pre-biased output, avoiding reverse current flow during hot-plug or multi-rail sequencing. Its internal soft-start ramps the output to 95% of target in 1.25ms after EN goes high, limiting inrush current and preventing brownout of upstream supplies.
What thermal protection features does the TPS62824ADMQR include?
The TPS62824ADMQR incorporates thermal shutdown with a 150°C trip point and 20°C hysteresis. When junction temperature exceeds 150°C, the device halts switching and enters thermal shutdown; normal operation resumes only after TJ falls below 130°C. This protects against sustained overload or poor PCB thermal design.
