Product details
Overview
TPS62827DMQT from Texas Instruments is a synchronous step-down DC/DC converter optimized for 4A load applications with 2.5V–5.5V input and adjustable 0.6V–4.0V output, featuring 1% feedback voltage accuracy (–40°C to 125°C), DCS-Control topology, and 2.2MHz fixed-frequency PWM operation. It delivers up to 97% efficiency, integrates 26mΩ/25mΩ power MOSFETs, and supports active output discharge and power-good signaling in a compact 1.5mm × 1.5mm VSON-HR package - ideal for space-constrained industrial PC and SSD power rails.
For engineers reviewing the TPS62827DMQT datasheet, TPS62827DMQT pinout, TPS62827DMQT application, or TPS62827DMQT equivalent, key selection criteria include verified 4A continuous output capability, confirmed 1% output voltage accuracy over full temperature range, validated 4μA quiescent current in PSM mode, and documented compatibility with standard 0.47μH inductors and 3×10μF output capacitance per TI's typical application schematic.
Technical Context
The TPS62827DMQT implements adaptive constant-on-time DCS-Control with seamless transition between PWM and power-save mode (PSM), maintaining regulation stability during load transients while minimizing light-load quiescent current. Its control loop uses an internal 600mV reference and supports 100% duty-cycle operation for ultra-low dropout.
Functional safety features include hiccup-mode short-circuit protection triggered after 32 switching cycles, thermal shutdown at 150°C with 20°C hysteresis, and undervoltage lockout at 2.2V (160mV hysteresis). The device integrates active output discharge via SW pin sink (75–400mA) and open-drain power-good signaling with 100μs rising-edge deglitch delay.
Key Specifications

| Protection features | Hiccup short-circuit, thermal shutdown (150°C), UVLO (2.2V), and active output discharge - reduces need for external fault management circuitry. |
Pinout & Package
TPS62827DMQT is housed in a thermally enhanced 6-pin VSON-HR (DMQ) package measuring 1.5mm × 1.5mm with wettable flanks and an exposed thermal pad. The package supports high-density layout and efficient PCB heat dissipation via bottom-side copper connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0V min); pulling low disables converter and activates output discharge. |
| PG | Power-good open-drain output | Sinks up to 1mA; requires external pullup ≤5.5V; provides 100μs deglitched status for rail sequencing. |
| FB | Feedback input | Connects to resistor divider for adjustable output; 600mV internal reference enables 0.6V–4.0V programming. |
| GND | Ground reference | Primary return path for control circuitry and power stage; must be low-impedance connection to thermal pad. |
| SW | Switch node | Drives external inductor; carries high di/dt current; requires tight layout to minimize EMI and voltage spikes. |
| VIN | Input power supply | Accepts 2.5V–5.5V; requires local 4.7μF ceramic capacitor placed adjacent to pin for high-frequency decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Combines fast transient response (<10μs recovery from 1A step load) with stable 2.2MHz switching across input/output conditions. |
| 1% output voltage accuracy | Maintains ±6mV error at 0.6V and ±40mV at 4.0V over full temperature range - eliminates need for post-regulation trimming in precision systems. |
| 4μA quiescent current | Enables >1-year battery life in coin-cell-powered sensors operating at 10μA average system load. |
| Active output discharge | Discharges output to <100mV within 1ms after disable - prevents back-powering of upstream circuitry and meets IEC 62368-1 safe discharge requirements. |
| 100% duty-cycle operation | Supports VIN-to-VOUT differentials as low as 120mV at 4A (based on 26mΩ HS-FET RDS(on)) - critical for low-dropout LDO replacement in brownout scenarios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62826DMQT | 3A output rating, identical 2.5V–5.5V input and 1% accuracy, same package and pinout. | Lower current capability limits use in 4A+ loads; suitable where derating or thermal headroom is acceptable. | Select when system peak load is ≤3A and cost optimization is prioritized over margin. |
| TPS62827ADMQT | Forced-PWM only (no PSM), 8mA quiescent current, identical 4A rating and package. | Eliminates frequency variation at light load but increases no-load power consumption by 2000×. | Choose for noise-sensitive analog circuits requiring fixed 2.2MHz switching and minimal output ripple. |
Compared with TPS62827DMQT, TPS62826DMQT offers lower current capacity but identical efficiency and accuracy for margin-constrained 3A designs, while TPS62827ADMQT trades ultra-low quiescent current for deterministic PWM operation - making the base TPS62827DMQT optimal for battery-powered 4A applications requiring both efficiency and transient performance.

FAQ
What is the maximum continuous output current supported by the TPS62827DMQT?
The TPS62827DMQT is rated for 4A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). This is validated across the full 2.5V–5.5V input range and 0.6V–4.0V output range, with thermal shutdown engaging only if junction temperature exceeds 150°C. Derating may be required in high-ambient or poorly ventilated layouts.
Does the TPS62827DMQT support adjustable output voltage, and how is it configured?
Yes, the TPS62827DMQT supports adjustable output voltage from 0.6V to 4.0V using an external resistor divider connected to the FB pin. With a precise 600mV internal reference, the output is set by R1 = R2 × (VOUT / 0.6V − 1), where R2 ≤ 100kΩ. For example, 1.8V output uses R2 = 100kΩ and R1 = 200kΩ. Fixed-output variants exist but TPS62827DMQT is adjustable-only.
What protection features are integrated into the TPS62827DMQT?
The TPS62827DMQT integrates hiccup-mode short-circuit protection (32-cycle detection, 100μs off-time), thermal shutdown at 150°C (20°C hysteresis), undervoltage lockout at 2.2V (160mV hysteresis), and active output discharge (75–400mA sink via SW pin). These eliminate the need for external fault-handling components in most end equipment.
Can the TPS62827DMQT operate with a 2.5V input and deliver 2.4V output?
Yes, the TPS62827DMQT supports 100% duty-cycle operation, enabling dropout voltages as low as ~120mV at 4A (based on 26mΩ high-side FET RDS(on)). At 2.5V input and 2.4V output, the device maintains regulation with minimal conduction loss, making it suitable for brownout recovery and low-VIN hold-up scenarios without external LDO supplementation.
Is WEBENCH® Power Designer support available for the TPS62827DMQT?
Yes, TI's WEBENCH® Power Designer fully supports the TPS62827DMQT. Users can enter target VIN, VOUT, and IOUT to generate complete schematics, perform efficiency and thermal simulations, optimize for footprint or cost, and export to CAD tools - all with real-time component pricing and availability from authorized distributors.
