Product details
Overview
TPS62162DSGT from Texas Instruments is a fixed-output 5.0 V, 1-A synchronous step-down DC/DC converter with DCS-Control™ topology, operating from 3 V to 17 V input and delivering up to 1 A continuous output current in a 2.00 mm × 2.00 mm WSON-8 (DSG) package. It integrates power good (PG), undervoltage lockout (UVLO), thermal shutdown, and seamless PWM-to-power-save mode transition - used in POL supplies for mobile PCs, digital cameras, and embedded systems.
For engineers reviewing the TPS62162DSGT datasheet, TPS62162DSGT pinout, TPS62162DSGT application, or TPS62162DSGT equivalent, key selection criteria include its 5.0 V fixed output, 2.25 MHz nominal switching frequency, 17 µA quiescent current in power save mode, 100% duty cycle capability, and open-drain PG signal for rail sequencing.
Technical Context
The TPS62162DSGT implements DCS-Control™ - a hybrid regulation architecture combining voltage-mode feedback with direct AC output voltage sensing via fast comparator control of switch timing. This enables stable operation with low-ESR ceramic capacitors and fast transient response without external compensation.
It operates in PWM mode at ~2.25 MHz under medium/heavy loads and transitions seamlessly into power save mode at light loads, reducing switching frequency linearly while maintaining regulation. Internal 0.8 V reference, integrated high- and low-side MOSFETs (RDS(on) = 300 mΩ / 120 mΩ at VIN ≥6 V), and 100% duty cycle support enable efficient conversion down to VIN ≈ VOUT + 15%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±3% accuracy over line/load/temperature - eliminates need for external feedback resistors and simplifies layout. |
| Input Voltage Range | 3 V to 17 V - supports single/dual Li-ion batteries and standard 12-V intermediate rails without external pre-regulation. |
| Max Output Current | 1 A continuous - sufficient for core logic, FPGA I/O, or sensor subsystems in space-constrained portable designs. |
| Switching Frequency | Typ. 2.25 MHz - enables use of 2.2 µH inductors and compact 22 µF output capacitance for high power density. |
| Quiescent Current | 17 µA in power save mode - extends battery runtime in always-on or low-duty-cycle applications like IoT sensors. |
| Power Good Output | Open-drain PG with 92–98% rising threshold - provides reliable system-level power sequencing and fault indication. |
| Thermal Shutdown | 160°C trip with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
| Package | WSON-8 (DSG), 2.00 mm × 2.00 mm with exposed thermal pad - delivers 61.8°C/W θJA for high-efficiency thermal management in dense layouts. |
Pinout & Package
TPS62162DSGT is housed in an 8-pin WSON (DSG) package measuring 2.00 mm × 2.00 mm with an exposed thermal pad soldered to AGND for optimal thermal performance and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pin 1) | Power ground return | Low-impedance path for high-frequency switch node current; must be connected directly to input capacitor ground plane. |
| VIN (Pin 2) | Main input supply | Accepts 3–17 V; requires local 10 µF ceramic decoupling close to pin for EMI suppression and transient response. |
| EN (Pin 3) | Enable control input | Active-high logic; internal 400 kΩ pull-down ensures safe default-off state; enables precise power rail sequencing. |
| AGND (Pin 4) | Analog ground reference | Separate ground for FB/VOS/PG circuitry; must be tied to PGND only at single point near input capacitor to avoid noise coupling. |
| FB (Pin 5) | Feedback input | Internally connected to AGND for fixed 5.0 V version; unused but must be shorted to AGND per datasheet for thermal stability. |
| VOS (Pin 6) | Output voltage sense | Direct connection to output capacitor; provides accurate regulation by sensing true output voltage at load point. |
| SW (Pin 7) | Switch node | Drives external 2.2 µH inductor; high dv/dt node requiring minimized trace area and guard ring to reduce EMI. |
| PG (Pin 8) | Power good indicator | Open-drain output requiring external pull-up (to ≤7 V); signals valid 5.0 V output with 92–98% threshold window. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Combines fast AC output sensing with DC feedback for stable regulation using small ceramic capacitors and no external compensation. |
| Seamless power save mode | Automatic transition from 2.25 MHz PWM to variable-frequency PSM below ~100 mA load - maintains >85% efficiency down to 10 µA output current. |
| 100% duty cycle operation | Enables regulation when VIN drops to ~15% above VOUT (e.g., 5.75 V → 5.0 V), extending battery life in Li-ion discharge profiles. |
| Integrated protection | Includes UVLO (2.7 V ±180 mV), thermal shutdown (160°C), short-circuit limiting (1.45–2.45 A), and soft-start (25 mV/µs ramp). |
| Pin-to-pin compatibility | Shares footprint and functionality with TPS62170 (3–17 V, 1 A) and TPS62125 (3–17 V, 0.5 A), enabling scalable BOM reuse across product families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62161DSGT | Fixed 3.3 V output; identical pinout, package, and specs except VOUT and FB connection requirement. | Used where 3.3 V logic rail is required instead of 5.0 V; same thermal and layout constraints apply. | Select TPS62161DSGT only when system requires 3.3 V - no rework needed beyond changing output capacitor value. |
| TPS62170DSGR | Adjustable output (0.9–6 V), same 3–17 V input, 1 A rating, and DCS-Control™, but in 3 mm × 3 mm VSSOP-8 (DGK) package. | Suitable for designs needing flexible VOUT tuning or higher thermal margin (θJA = 184.3°C/W vs. 61.8°C/W), but occupies 2.25× more PCB area. | Choose TPS62170DSGR if adjustable output or legacy VSSOP footprint is mandatory; not drop-in due to larger package and different thermal pad. |
Compared with TPS62162DSGT, TPS62161DSGT offers identical performance at 3.3 V with no layout change, while TPS62170DSGR trades compact size for adjustability and lower thermal density - making TPS62162DSGT optimal for space-constrained 5.0 V POL applications.

FAQ
What is the output voltage tolerance of the TPS62162DSGT over temperature and load?
The TPS62162DSGT delivers a fixed 5.0 V output with initial accuracy of ±3% under PWM mode operation (VIN ≥ VOUT + 1 V), and ±3.5% to +4% in power save mode with 22 µF output capacitance. Line and load regulation contribute ≤0.05%/A and ≤0.02%/V respectively, ensuring stable 5.0 V delivery across –40°C to +125°C junction temperature and full 0–1 A load range.
Does the TPS62162DSGT require external feedback resistors?
No, the TPS62162DSGT is a fixed-output variant with internal resistor divider set to 5.0 V. Pin 5 (FB) must be connected directly to AGND per datasheet guidance to ensure thermal stability and optimal regulation accuracy - no external resistors are needed or permitted.
How does the power good (PG) signal behave during startup and fault conditions?
The TPS62162DSGT's PG pin is an open-drain output that remains high-impedance until VOUT reaches 92% of nominal (4.6 V), then pulls low only if VOUT falls below 87% (4.35 V). During EN assertion, UVLO, thermal shutdown, or VIN removal, PG goes high-impedance - enabling unambiguous system-level sequencing and fault isolation without external logic.
Can the TPS62162DSGT operate with input voltage below 3 V?
No - the TPS62162DSGT has a guaranteed minimum operating input voltage of 3 V per Recommended Operating Conditions. Its undervoltage lockout activates at 2.6–2.82 V (typ. 2.7 V), disabling switching and forcing PG high-impedance. Operation below 3 V is not characterized and may result in unstable regulation or undefined behavior.
What is the recommended inductor and output capacitor for the TPS62162DSGT?
Texas Instruments specifies a 2.2 µH shielded power inductor (e.g., TDK SPM5030 or Coilcraft XAL5030) and 22 µF low-ESR ceramic output capacitor (X5R/X7R, 10 V rating) for optimal efficiency, transient response, and EMI performance. Input requires ≥10 µF ceramic (X5R/X7R, 25 V) placed within 3 mm of VIN and PGND pins.
