Product details
Overview
TPS62067DSGR from Texas Instruments is a synchronous step-down DC/DC converter delivering up to 2 A output current with 3-MHz fixed-frequency PWM or auto PFM/PWM mode operation, ±1.5% output voltage accuracy in PWM mode, open-drain power good (PG) output, and 18 µA quiescent current - designed for point-of-load regulation in space-constrained portable electronics.
For engineers reviewing the TPS62067DSGR datasheet, TPS62067DSGR pinout, TPS62067DSGR application, or TPS62067DSGR equivalent, key selection considerations include its 2-mm × 2-mm WSON-8 package, integrated PG signal for rail sequencing, voltage positioning for load-step response, and compatibility with 1-µH inductors and 10-µF ceramic output capacitors.
Technical Context
The TPS62067DSGR employs a voltage-mode control architecture with input voltage feed-forward, enabling fast line/load transient response and stable operation with small external components. Its dual-mode operation - automatic PFM/PWM transition at light loads and forced PWM via MODE pin (not applicable here, as TPS62067 defaults to auto mode) - maintains >95% efficiency across 0–2 A load range while minimizing output ripple.
It integrates high-side and low-side MOSFETs with typical RDS(on) of 120 mΩ / 90 mΩ (at VIN = 3.6 V), supports 100% duty cycle for ultra-low dropout, and includes internal discharge resistor (75–1450 Ω) activated during shutdown to fully discharge VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.9 V to 6 V - compatible with 3.3-V and 5-V system rails; enables single-supply POL from common intermediate buses. |
| Switching Frequency | 2.6–3.4 MHz (typ. 3 MHz) - allows use of sub-1-µH inductors and compact 0603-size ceramics; reduces EMI filter size. |
| Max Output Current | 2 A - sufficient for powering core logic, DSPs, or memory subsystems in portable devices without external current boosting. |
| Output Voltage Accuracy | ±1.5% in PWM mode - ensures tight regulation for sensitive digital loads; feedback reference is 600 mV. |
| Quiescent Current | 18 µA (typ.) in PFM mode - extends battery life in always-on or low-power standby states. |
| Power Good Output | Open-drain PG with 5-µs delay, 93–98% rising threshold - provides reliable rail-valid signaling for microcontroller reset or supply sequencing. |
| Junction Temp Range | –40°C to 125°C - qualified for industrial and extended-temperature portable applications; thermal shutdown at 150°C. |
Pinout & Package
TPS62067DSGR is housed in an 8-pin, 2.0 mm × 2.0 mm × 0.75 mm WSON package (DSG suffix) with exposed PowerPAD™ for enhanced thermal dissipation. The package is RoHS-compliant and requires soldering the PowerPAD to PCB ground plane for optimal thermal performance (RθJB = 35.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN | Power input (high-current path) | Connects to input capacitor and supplies power stage; separate from AVIN to reduce noise coupling. |
| PGND | Power ground | Return path for high-current switch node; must be routed separately from AGND to minimize switching noise. |
| EN | Enable control input | Active-high logic; pulling low disables device and activates internal SW-to-PGND discharge path. |
| FB | Feedback input | Monitors output voltage via external resistor divider; sets regulated VOUT = 0.6 V × (1 + R1/R2). |
| PG | Power good open-drain output | Asserts high when VFB ≥ 95% of target; requires external pullup; used for system sequencing or fault indication. |
| SW | Switch node | Connects to inductor; carries high di/dt switching current; requires tight layout and minimal trace length. |
| AGND | Analog ground | Reference for control circuitry; must be connected to PVIN ground near AVIN to avoid ground bounce. |
| AVIN | Analog power supply | Bias supply for internal regulators and error amplifier; must be decoupled locally and tied to PVIN. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage positioning in PFM mode | Regulates VOUT 1% above nominal to reduce undershoot during sudden load increases - critical for DSP/core voltage stability. |
| Integrated output capacitor discharge | Internal resistor (75–1450 Ω) discharges VOUT when EN = low - eliminates floating voltage and ensures monotonic startup. |
| 100% duty cycle operation | Enables dropout <100 mV at full load near VIN = VOUT - maximizes usable battery voltage range in 1.8-V or 2.5-V systems. |
| Clock dithering | ±6 ns frequency modulation spreads EMI energy - simplifies compliance with CISPR-22 Class B conducted emissions limits. |
| Undervoltage lockout (UVLO) | Hysteresis between 1.78 V (falling) and 1.95 V (rising) prevents brownout oscillation during battery depletion. |

FAQ
What is the function of the PG pin on the TPS62067DSGR?
The PG (power good) pin on the TPS62067DSGR is an open-drain output that signals valid regulation status. It asserts high when the feedback voltage reaches ≥95% of the target output voltage, with a 5-µs internal delay, and pulls low when VFB falls below ~90%. An external pullup resistor is required, and the pin supports rail sequencing and microcontroller reset functions in the TPS62067DSGR design.
Does the TPS62067DSGR support adjustable output voltage?
Yes, the TPS62067DSGR supports adjustable output voltage via an external resistor divider connected to the FB pin. With a 600-mV internal reference, VOUT = 0.6 V × (1 + R1/R2). The device operates across 0.8 V to VIN, enabling configurations such as 1.2 V, 1.8 V, or 2.5 V outputs - all validated in the TPS62067DSGR datasheet's typical application schematics.
How does the TPS62067DSGR handle shutdown and output discharge?
When the EN pin is pulled low, the TPS62067DSGR enters shutdown mode, reducing current draw to <1 µA. Simultaneously, an internal switch connects the SW pin to PGND through a 75–1450 Ω resistor, actively discharging the output capacitor. This ensures the TPS62067DSGR starts from 0 V on next enable - preventing residual charge issues and enabling reliable monotonic power-up sequences.
What inductor and capacitor values are recommended for the TPS62067DSGR?
The TPS62067DSGR is optimized for a 1-µH inductor (e.g., NRG4026T 1R2) and 10-µF ceramic output capacitor (0603 size). Input capacitance of 10 µF is also recommended. These values enable full 2-A capability, maintain stability across temperature, and achieve >95% efficiency - as confirmed in the TPS62067DSGR datasheet's efficiency curves and layout guidelines.
Is the TPS62067DSGR pin-compatible with other devices in the TPS6206x family?
Yes, the TPS62067DSGR shares identical 8-pin WSON (DSG) packaging and pinout with TPS62065DSGR, including PVIN, PGND, EN, FB, PG, SW, AGND, and AVIN assignments. This allows direct substitution in layouts where PG functionality is added or leveraged - though firmware or external circuitry may require adjustment to utilize the PG signal in the TPS62067DSGR implementation.
